Executive Summary: The Paradigm Shift TL;DR — The 30-Second Brief For nearly two decades, “Autoflower” was a dirty word in serious cultivation circles. If you were growing Cannabis ruderalis hybrids in 2010, you were likely hiding a stunted, leafy “Lowryder” in a PC tower case, hoping for a quarter-ounce of 12% THC flower. It was […]

With so many different strains of cannabis out there, growers are becoming more and more concerned with maintaining desirable genetics. Since no two plants will ever develop identically, cloning has long been the industry standard for preserving cannabis genes. Recent advancements, though, have given growers a new tool: Tissue culture.

More and more cannabis users are choosing to grow their own flowers because resorting to the black market is usually neither the most convenient nor the cheapest option. For this reason, every day more recreational and therapeutic consumers are taking the step into cannabis home growing so they can be self-sufficient and not have to rely on third parties.

However, starting indoors can be tricky if you don’t know where to begin, so in this post, we’re going to focus on the most common mistakes made by new growers when they first get into the exciting world of cannabis cultivation. Let’s go!

Bad calculation of the area and dates of cultivation

The purpose of home growing is to be self-sufficient in the cannabis we consume, and to do this, we must calculate how much cannabis we will need to grow to meet our needs. We need to make an estimate of our annual cannabis consumption and divide it by the number of harvests that we intend to carry out over the course of the year.

When we begin to cultivate, and especially if we do not have air conditioning and a bit of previous experience, it’s best to start in September and finish in April, taking advantage of the low temperatures in autumn and winter. From spring, temperatures begin to be high (very high in some areas) and would require air conditioning to allow us to maintain adequate temperatures in the grow. Between autumn and winter, we could carry out 2 harvests without a problem.

Thus, depending on personal consumption, we will calculate the necessary growing space and opt for a tent with a size that is adequate for our needs, always rounding down our yield calculations, estimating a maximum of 300-350g per m2 of dried flower per crop, that is, every 3 months.

[productes tipus=”fitxa” cat=”476″ nfitxes=”3″]

Inadequate lighting and air renewal

Our grow tent must have an adequate lighting system if we want to optimise cultivation and produce good buds. It is not advisable to use energy-saving light bulbs for flowering, but rather to invest in professional lighting, whether a sodium, LEC, or LED system; the results will always be better than CFL or energy-saving bulbs. While it is possible to flower cannabis plants with this type of lighting, the results will never be comparable to discharge lights (HPS, HM, LEC/CMH) or modern LED panels.

The air renewal system is often an afterthought, despite being just as important as lighting, possibly even more so. In a home-cultivation tent, an air extractor fan connected to an active carbon filter to prevent odours from escaping is more than enough (uninterrupted 24-hour operation is recommended), so we eliminate any smells while we renew the air inside the tent. In small spaces, we do not usually need to pull air into the growing space with another fan, because by leaving one of the vents in the tent slightly open, we can generate a passive airflow. Remember that a small fan installed inside the tent is always a good idea to remove the air around the plants.

Bad choice of seeds

Once we have the tent, the lighting, and the air renewal system (extractor and filter), then it’s time to start thinking about seeds, an issue that has a huge influence on the success of our first crop. A typical rookie mistake is to buy the most expensive seeds available, those that are currently in fashion or those with too long a flowering time. Clearly, if the objective is to finish the grow without major complications, then choosing a fast-flowering variety that does not demand high cultivation skills is the best option.

Once we’ve gained a little more experience and have a full stash, then we can choose varieties with greater difficulty of cultivation. A good option is to start with feminised seeds to ensure all the plants are females and not to grow males, only to discard them, leaving empty spaces in the tent, as happens when growing regular seeds.

Indica-dominant hybrids and Early or Fast Version genetics are the best places to start, with plenty of varieties to choose from.

[productes tipus=”fitxa” tag=”90″ nfitxes=”3″]

Not using a quality substrate

It is vitally important to choose a professional substrate and not opt ??for those that we can find in dollar stores or similar shops at much cheaper prices. This is because low-end growing soils don’t usually have the most appropriate substrate texture, pH, or nutrients, and in most cases, they come without being sterilised. They may give good results when growing geraniums on the balcony, but when growing cannabis, it is always better to use a specific substrate from an established brand if we want to avoid problems. For our first crop, a very good option is the so-called ?All Mix type? substrates, as they come pre-fertilised with enough food for the first weeks of growth, meaning that we don’t have to worry about using additional fertilisers until flowering.

Excess growth

The next common mistake is to prolong plant growth too long before switching the photoperiod to flowering. We must bear in mind that, once the plants enter flowering, they will begin to stretch and, depending on the genetics, they may even grow to triple the size they were before changing the photoperiod. It is a very common mistake to watch the plants grow bigger and bigger and not pass them to flowering!

We must also bear in mind that the branches and flowers in the lower parts of the plant will not develop as well as the higher ones, so we shouldn’t waste time waiting for them to grow, which is a useless waste of light without adding to the final yield. In many cases, it is best to prune these lower parts away and let the plant’s energy focus on the tips.

Excess irrigation

Another of the most common mistakes among most people who are new to indoor growing is overwatering. In principle, we imagine that by watering more and often, our plants will grow bigger and better, but nothing is further from the truth! When we grow with soil it is necessary to let the substrate dry before watering again, unlike tomato plants that like to have a certain degree of moisture in their roots, the opposite happens to cannabis, the substrate needs to be almost dry (but never completely dry or the plant will, of course, dehydrate in a few hours) before watering the plants again.

Interruption of the photoperiod (light pollution)

When we grow photoperiod seeds, which, unlike automatic seeds, grow or bloom depending on the hours of darkness received, we must respect the night period of the plants, so that no light should enter the tent during the dark period under any circumstances. Sometimes growers have used the sleep period of their plants to open the tent and check the plants or carry out irrigation, pruning, tying… but after more than a month in the flowering photoperiod they do not observe any changes in the plants; light pollution is another avoidable mistake by using green light in the crop or simply working on it when the lamps are on.

Also, make sure that none of the devices inside the growing space emit any type of light during the night period of the plants, as well as checking that no outside light can enter through any slit or opening (yes, zipping ourselves inside the closet with the light off is the best way to check!).

Curing before preventing

According to the saying, prevention is better than cure, but, unfortunately, in most cases, this practice is not used in cultivation until some experience has been gained thanks to past mistakes. If we do not have the correct cultivation parameters under control – such as temperature and humidity – or we do not take the pertinent hygiene measures in the grow, pests and pathogens may appear in our grow, from fungi to aphids right up to the dreaded red spider mites. It’s usually enough to apply a different preventive product once a week to keep most pests at bay, especially during growth and pre-flowering (first 2 weeks of flowering); normally, when this is not done and a plague develops, we often don’t realise until the plants are flowering, a period in which the use of insecticides or fungicides is not recommended.

[productes tipus=”fitxa” ids=”12726,11449,8049″]

Premature harvest

After weeks of work and with the flowering phase well advanced, we can already see that our precious flowers are a good size with a dense layer of resin. A very common mistake due to eagerness or because our stash is low (it’s happened to all of us!) is to harvest too early; We should wait to harvest and let the flowers explode, cutting them at the optimum point of maturation so that they fatten as much as possible and their cannabinoid and terpene content is at its maximum peak.

Harvesting ahead of time reduces crop production, the flowers won’t look the way they should, and the terpenes won’t be at their best. Remember that 10-15 days before the estimated cut-off date, we must carry out a root wash so that our plants do not continue to absorb nutrients and so we will be able to enjoy the taste of flowers 100% free of nutrients and in all their splendor.

Flushing cannabis plants

Bad drying

It is logical that before starting the cultivation, we think about where to dry our harvest, although in many cases this question is not usually asked in our first crop until the day of the chop or even hours before the harvest. Making sure we have a suitable place to dry cannabis and doing it in the right way is how a grow should be finished because drying incorrectly is a really great way to ruin months of work.

One of the best options to dry the cannabis crop is to use the same tent we grew in, taking advantage of the extraction and the carbon filter, so that we renew the air and avoid the problem of the smell of the plants while drying slowly (about 2-3 weeks) and in complete darkness. Don’t be tempted by the idea of ??drying inside a closed tent without ventilation, in glass jars, or in a Tupperware or box, because without adequate ventilation, we will ruin our harvest!

We hope that all those who are thinking of starting to grow indoors will find this helpful. They are very basic concepts, but most beginners fall into at least one of these easily avoidable errors. Who can say this never happened to them?

Happy growing!

Summer is already here and we’re sure that many of you already have a beautiful outdoor garden with plants in full growth. Perhaps you started growing from seeds, or maybe you keep mother plants and moved some clones outside in the last few weeks. However you start, outdoor cannabis cultivation in summer is usually relatively simple, as the weather is good and the plants develop splendidly as long as they have the correct nutrients and irrigation they need.

However, and those of you who keep mother plants indoors while you move clones outside you will know this well, growing indoors in summer can be a real nightmare! This is mainly due to the elevated temperatures that indoor grow rooms and tents can reach, which can not only get so high as to be incompatible with proper plant growth but can also increase pest pressure and other problems. Today we’d like to tell you a few tricks that will allow your indoor mother plants to spend the summer in comfort and be ready to provide all the clones you need once the indoor growing season begins.

Avoid heat stress in cannabis plants

We’ll start from a situation where we need to keep a few mother plants growing indoors during the summer and, of course, without using an air conditioning unit, which would make it really easy for us to maintain them correctly at constant temperatures of 24ºC! So, we find ourselves in the same situation as many growers, using a small basic room or grow tent without air conditioning, where we must keep our mother plants in the best possible conditions to be able to start the first indoor crop of the season once the cooler weather of late summer allows us to.

We’ll go over the various cultivation parameters to see what we can do to improve the state of the plants in each case and allow them to spend the summer in much less stressful conditions than if we carried on cultivating in exactly the same way that we would, for example, in winter. It’s worth remembering that we probably won’t achieve the same growth rate as in spring or autumn, but we will have healthy plants at the end of summer. After all, it’s much better to be able to get 10 good clones from a healthy plant than 15 from one in poor condition!

[productes tipus=”fitxa” cat=”476″ nfitxes=”3″]

Light and heat in indoor cultivation

As we know, aside from the ambient temperature, the main source of heat that indoor plants receive comes from the lighting system. If we grow with LED panels this probably won’t be an issue, but in the case of using discharge lamps such as metal halide (HM), sodium vapor (HPS) or ceramic halide (CMH), the heat emitted by these can become a real headache. If we have an electronic ballast that allows us to regulate the power of the lamp, it’s a good idea to set it to 50-60% of its capacity.

Of course, if our budget allows it, we can use LEDs in summer and discharge lamps during the rest of the year. We can opt for professional panels such as the Lumatek Zeus, or if we have a tighter budget, use the Slim LED by Farming Monkey for growth or the TLED bars from Secret Jardin. The latter are particularly useful, as they always spread the light very well and can be used as supplementary lighting on the sides of the grow space, or for seedlings and clones.

In short, the trick is either to replace our discharge lamps with LED panels or to lower their power output using an electronic ballast. In this second case, LEDs can often also be used as supplementary lighting if you don’t want to reduce the rate of growth and ensure that the plants receive more light. Finally, and in relation to lighting, we can lose a couple of hours of daily light without a problem by using a 16/8 photoperiod; the plants will continue in vegetative growth and won’t go into flower, and we’ll have two hours less with the lights on every day. It ought to go without saying, but we should always try to have the lights switched on at night and during the cooler hours of the morning or afternoon, always avoiding the hottest time of day outside (midday). These are only small details, but as you’ll see at the end of the post, everything adds up eventually!

Ventilation in the grow space

Ventilation plays an important role indoors, both evacuating the hot air from the grow to the outside and bringing fresh air inside. In addition, during summer, air-cooled Cooltube reflectors can be used for the lamps, which are connected to the extraction system and help to lower the temperature within the room or tent by a few degrees. The extraction can be left constantly connected and at full power, if a potentiometer or a climate control unit is available, especially during the hottest time inside the grow space.

Regarding the fresh air intake, we must try to take air from the coolest place possible, which might not be from outside the building but from another room. Indeed, and depending on the location of the grow space and how the air intake system is set up, it may be more recommendable to take air from inside a home than from outside. Keep in mind that a flow of hot air entering the grow space is the last thing we want!

When positioning the fans that move air around inside the growing space, it’s important to place them so that the air does not blow directly onto the plants, which would cause excess transpiration. It is far better to focus them on the lamp and towards the air extraction intake, ensuring that the pocket of hot air that forms in the upper part of the room or tent is expelled more efficiently by the extractor.

Vapour Pressure Deficit – humidity and heat in the grow room

As you can see in much more depth in our article on temperature and humidity in cannabis cultivation, vapour pressure deficit or VPD is a key factor for the plants’ development, which also takes on special importance during the hottest months of the year. Broadly speaking, what we need to do is adjust the temperature and humidity to achieve the best possible development, which can be achieved by following the chart in the linked article at the end of this section.

[productes tipus=”ficha” ids=”11754,11957,9164″]

To give you a general idea, what we must do when temperatures skyrocket (as well as trying to lower them in other ways) is to balance humidity levels according to the temperature. In most cases, during the summer, we will have to increase the humidity inside the growing space so that the plants can cope with the high temperatures much better than if they were in a low-humidity environment.

However, since the high temperatures mean that we are unable to stop the extractor to raise the humidity, the best way to achieve this is by means of a humidifier, which we can connect to the same timer as the lamp so that it starts up whenever the lights come on. Depending on the size of the room or grow tent, a humidifier with a larger water tank will be needed (to allow it to run for at least 16-18 hours at a time).

Vapour pressure deficit (VPD) in cannabis cultivation

Irrigating cannabis in high temperatures

Logically, the higher the ambient temperature, the more irrigation our plants will need, since both their water consumption and their evaporation will be greater. It is therefore normal that we must water more frequently to prevent our plants from wilting. To give an example, the same mother plants grown in the same-sized container can require more than twice as much water on a hot summer’s day as they would on a winter one. As we can see, factors such as environmental temperature and humidity have a direct effect on the amount of water our plants consume.

If we have adjusted the VPD correctly, we will probably have fairly high humidity levels, so our plants won’t need as much water as if we weren’t using humidifiers to reach the VPD range we’re aiming for. If we don’t have the correct VPD, our plant will need watering more frequently, as the humidity will be lower and the plants will have less water in the environment.

Another important factor in summer is the water temperature. We must avoid at all costs watering with water that’s too warm! The ideal temperature of the irrigation water is always around 20ºC; with higher temperatures, the water loses oxygen rapidly, which can have a serious impact on the development of plants. At lower temperatures, certain nutrients cannot be assimilated, although we’re fairly sure that this won’t be a problem in summer!

Preventing pests in summer

Summer is usually the worst time of the year for the appearance of insect pest problems. Depending on your area, not all of them may appear, although we recommend that you don’t lower your guard and continue taking preventive measures against pests such as spider mites, thrips, or whiteflies. On the one hand, reducing the heat and increasing the humidity within the grow space will help us greatly, although using preventives such as potassium soap or neem oil on a regular basis is just as important.

Feeding cannabis plants in summer

Once again, we have two possible scenarios: if we’ve regulated the temperature and humidity to achieve an acceptable VPD range, our plants can continue to receive the same amount of nutrients that they would normally receive in, for example,  spring or autumn. We shouldn’t have any problems with salt buildup in the substrate since the irrigations will be relatively infrequent and the plants will have time to absorb most of the nutrients.

On the other hand, if we don’t have the VPD dialed in, our plants will require more irrigation, meaning that we should reduce the dose of nutrients provided in each watering. In this case, we’ll feed the plants using approximately 60% of the fertiliser dose used in spring, keeping a close eye on the plants to check for any nutrient deficiencies. If this is the case, we can slightly increase the amount of fertiliser added to the nutrient solution.

Products to reduce heat stress in plants

Finally, we’d like to recommend some of the products currently on the market that can help to protect your plants from high temperatures. As you can see, in many cases these additives are rich in silicon, a crucial element in the development of plant cell structure. These are some of the most commonly used today:

• Vitalink Chill
• Elycitor from Biotechnology
• X-Force from BioGreen
• Pro-Silicate by Grotek
• Silica Blast by Botanicare
• Barrier by Top Crop

We hope that these simple tricks will mean that your indoor plants can spend a comfortable and stress-free summer without suffering too much from the high temperatures. Please don’t hesitate to share any tips of your own, as well as any questions or doubts that may arise… We’ll be happy to answer you, as always!

Happy growing!

With its Controller 69 PRO and the Cloudline PRO T4 extractor, the American climate control brand puts smart technology in your hands that automates the climate in your room or grow closet with both elegance and efficiency.

Because growing indoors doesn’t have to be complicated. All it takes is the right equipment to make it a much simpler and more manageable activity. Today, we’re introducing you to these two magnificent devices, which, as you’ll see, will make your life much easier.

The importance of proper climate management

You may have the best seeds on the market, the most fertile substrate, and LED lighting that would make a TV studio pale…but if you don’t properly control your growing climate, you’re likely to end up with problems that will translate into stress for your plants, and for you too.

Temperature, humidity, and the famous VPD (vapor pressure deficit) are the invisible variables that determine success or failure. Too much humidity during flowering and goodbye buds; poorly managed temperatures and pests can take over your crop. The plant speaks to its environment, and if you don’t provide the atmosphere it needs, it will make it clear with twisted leaves, poor development, and a yield that leaves much to be desired.

This is where systems like AC Infinity make a world of difference. Because it’s not just about extracting air: it’s about creating a stable, dynamic microclimate adapted to each phase of the growing process. An environment where plants grow safely, comfortably, and with everything in their favor to show you their true potential.

Managing the climate well isn’t a luxury; it’s a necessity that, if properly addressed, will pay off at harvest time. And if you do it automatically, precisely, and remotely…that’s what proper farming is all about!

[productes tipus=”fitxa” cerca=”AC Infinity” nfitxes=”3″]

Controller 69 PRO: the brain of your crop

Imagine the situation: your indoor grow is going great, but you spend half your life adjusting fans, controlling the temperature, increasing the humidity…until you realize you need a brain to take care of it for you. Well, this is what the AC Infinity Controller 69 PRO does: a small device that centralizes the climate control of your grow room or cabinet, turning this tedious and delicate task into child’s play.

Thanks to its Wi-Fi connectivity and mobile app, you can control everything from your smartphone: humidity, temperature, fan speed, light intensity…even program routines based on the growing phase. Entering flowering? Change the profile with a click. Detect excessive humidity in the readings? Adjust the fan from your bed or sofa. No cables, no complications. A real luxury!

And we’re not talking about a simple ON/OFF button: we’re talking about VPD-based automations, threshold exceedance alerts, downloadable climate histories, and even control of up to four devices in the UIS ecosystem: from extractors to lights, fans, and humidifiers. And all of this is orchestrated with a backlit touchscreen LCD that’s also very intuitive and easy to use.

Cloudline PRO T4: a smart air extractor

If the controller is the brain, the Cloudline PRO T4 would be the muscle. But beware, it’s not that raw muscle that makes noise and consumes like a stove. Here we’re talking about a silent, efficient, and intelligent extractor, designed to keep up with you cycle after cycle with a consistency that some humans would dream of.

Equipped with a mixed-flow EC motor and PWM control, this air extractor automatically adjusts its speed—and therefore the extracted air flow—based on the climate parameters it receives from the Controller 69 PRO. This means it doesn’t just ventilate: it adapts its speed to your plants’ needs at any given time, maintaining a stable environment without you having to intervene.

And while doing all this, it barely generates 28 dBA of noise, making it the best friend of discreet growers and sensitive neighbors. The best part? Its installation is completely plug & play: no fancy tools or hassle. Plug it in, set it up, and it’s ready to go. As if all this weren’t enough, its robust design and IP44 certification also make it ideal for technical spaces such as AV rooms, racks, servers, or, of course, indoor grows or small greenhouses. In short: a professional extractor that doesn’t flinch even in the most demanding environments.

AC Infinity Complete Kits: Grow with everything from the very first minute

Are you one of those who want to set up a serious grow shop without having to complete a master’s degree in lighting, ventilation, and odor filtration? Then AC Infinity’s complete grow kits are your entry ticket to the world of professional indoor growing…without the hassle or headaches.

Available in two versions —60x60x180 cm and 120x60x180 cm—these systems come ready to assemble, connect, and start growing with surgical precision. They include everything you need: a robust cabinet, Samsung LM301H LED light, ultra-quiet ventilation, an odor filter, a smart controller, and all the accessories to ensure you can forget about improvisations.

With the Controller 69 PRO as your command center, you can control temperature, humidity, lighting, and ventilation from your phone, set up customized routines, and receive notifications if anything goes wrong. And all with the peace of mind of knowing your growing environment is optimized down to the last detail.

As for lighting, there are no cheap bulbs or mediocre lamps here: each kit includes an IonBoard panel with Samsung LM301H LEDs, guaranteed to deliver efficiency, a suitable spectrum, and true light penetration. 115W for the small model and 200W EVO for the large one.

Cloudline ventilation, along with activated carbon filters and CloudRay oscillating fans, renew the air, eliminate odors, and simulate a natural environment, all while remaining very quiet. And the CloudLab cabinet wraps it all up with its thick canvas, steel tubes, and Diamond-type reflective Mylar: strength and reflection in a single combo.

Oh, and don’t forget: they also come with geotextile pots, SCROG mesh, scissors, conduit, clamps, and heat tape. Because when AC Infinity says “complete kit,” they mean it.

In short, if you’re looking for a professional, silent, automated system with no room for error, these kits are like stepping into the grand scheme of indoor growing. Whether you’re starting your first plants or taking your grow to the next level, you’ll find everything you need here… and not a single screw is missing.

Grow without stress…or cables

Without a doubt, one of the biggest challenges of indoor growing is constant climate management. You’re constantly checking the fan, whether the humidity rises above 70%, whether the temperature spikes, or even whether the lights have turned on or not… a constant headache for every grower, who always has that anxiety looming over them if they’re not looking at their work—that is, their plants.

This is where AC Infinity makes the difference; once installed, the system operates automatically, connected via Wi-Fi and orchestrated from your mobile app. From germination to flowering, you define the profiles and the controller executes: no distractions, no adjustments, no drama.

Going on a trip? You control everything from your phone. The temperature spikes in the middle of August? You get a notification. Want to compare your last OG Kush grow with this one with Gelato? Export the weather data, and you’re ready to compare. Just don’t think that having the app installed means you’re compromising your security…no data will leave your phone, so do not worry!

Growing without being tied to a closet is now a reality. And we assure you, once you try it, there’s no turning back.

[productes tipus=”fitxa” tag=”86″ nfitxes=”3″]

Technology is within everyone’s reach

It’s not just that it’s modern. It’s that it works, and it works wonderfully. The AC Infinity app is clear, fast, and stable, something that in the world of cannabis gadgets is almost miraculous. No hidden menus, cryptic icons, or unreliable Bluetooth connections.

From the app, you can create schedules, program according to growing phases, view historical weather data with precise graphics, receive real-time alerts, and centrally control all UIS devices. Yes, it’s like one of those modern home automation systems, but for your plants.

And all this with a modern, clean, and intuitive interface that doesn’t exactly look like something straight out of a poorly translated technical manual from the 1990s. And the best part is that this smart connectivity doesn’t require a master’s degree in agricultural engineering: it’s designed for real growers, with real needs and limited time.

If you want to take a step forward as a grower, automate your climate management system, and, in the process, save yourself work and achieve better results, don’t hesitate: AC Infinity can become your best ally. If you’re interested in the technical specifications of these devices, don’t hesitate to check them out on our website; you’ll find them in their product descriptions.

Happy harvest!

We know. There’s nothing like watching your plants grow in the sun, with the breeze caressing their leaves and that wild aroma that makes you feel part of nature. Yes, we admit it, outdoor growing would be like a hippie-country dream come true. But between treacherous storms, nosy neighbors, pests, and harvests that seem straight out of Russian roulette… maybe it’s time for you to discover another growing method that, we assure you, can bring you great joy: indoor growing.

And no, we’re not saying you should give up on your outdoor adventures. On the contrary. Today, we want to suggest something even better: complement them.  Because growing indoors isn’t just an alternative. It’s, with the sun’s permission, the smartest way to ensure your harvests and achieve high-quality buds all year round. We’ll explain it in detail below.

Indoor Growing: Your Own Cannabis World

Growing indoors is like having your personalized microclimate, a bubble where you’re in charge and don’t have to worry about the whims of the weather. Want 18 hours of light a day? You’ve got it. Want 50% humidity and not a single bug around? You got it, too. It’s like going from the Amazon rainforest to a laboratory clean room, but with cannabis plants as the centerpiece.

Setting up an indoor grow room isn’t as complex or expensive as it seemed a few years ago. There are complete grow tents at reasonable prices, efficient LED lighting, and control systems that allow you to have everything ready with just a couple of clicks. In fact, if you take a look at this blog, you’ll find many articles that will help you better understand this method of growing, and above all, how to do it correctly.

The best part? You don’t need acres of land or to attract the attention of neighbors, police, or thieves… With a small space in a corner of your home or garage, you can get a more than decent harvest without anyone noticing and with the advantage of being able to harvest high-quality buds several times a year. But let’s not get ahead of ourselves and move on to the main advantages of indoor growing, especially when it comes to cannabis plants.

10 easy-to-avoid errors in your first indoor grow

Security: No one will know you have cannabis plants

Do you have neighbors with the hearing of a bat and the nose of a bloodhound? Do you live in an area where having a plant in the garden is equivalent to summoning the local police or the typical lowlife who prefers stealing rather than growing his weed? Indoor growing is the solution. Hidden behind four walls, no one sees, no one smells, no one suspects. With a good activated carbon filter and a closed cabinet, you won’t even realize how good it smells inside. Plus, if you’ve ever had to deal with someone “borrowing” your outdoor plants, you’ll know what we’re talking about. Indoors, the only hands that touch your flowers are yours. Period.

As if that weren’t enough, indoor growing allows you to spread your production over several harvests per year, eliminating the classic risk faced by outdoor growers who must provide enough buds for an entire year with a single harvest, and are therefore forced to manage a relatively high production… Why go through the hassle of growing more than a kilo of weed to be self-sufficient when, during the year, you can make several harvests of, for example, 300 grams? You can be sure… anyone who has been to court and knows what the matter is about will always prefer to answer for 300g of weed than for a kilo!

[productes tipus=”fitxa” cat=”444″ nfitxes=”3″]

Independence: neither climate nor seasons stop you

Any outdoor grower knows that they depend heavily on the solar calendar and the weather forecast. Indoors, you depend on your desire to improve the environment for your plants, as you can provide them with the ideal conditions for their development. And when we say ideal, we mean it literally. Temperature and humidity, CO2 levels, ventilation, daily light hours… all of these are parameters over which you can have complete control in your indoor grow, which translates into perfect conditions for growth and flowering, with the excellent results that this brings.

All of this also means you can harvest three, even four crops a year. Regardless of whether it’s snowing, pouring, or there’s a biblical plague of locusts. You control the three fundamental aspects of the crop: photoperiod, temperature, and humidity. There are no pauses, no waiting. No storms, no unsuitable temperatures. Want to plant in January? You can. Want to harvest in April and plant again in May? You can.

And this is where outdoor growers often say timidly: “Hey, this indoor growing stuff doesn’t sound that bad…” Well, let’s keep giving them something to think about!

Growing clones instead of seeds: savings and strategy

This is where the strategic factor comes in. By growing indoors, you can maintain mother plants and create clones, which means a considerable saving on seeds. But you can also use those clones for outdoor cultivation. In other words, you can prepare your arsenal indoors and then go out into the field with a head start. Indeed, many growers keep clones of their best plants in their indoor grow rooms until June (Northern Hemisphere), when they can take them outside without fear of flowering. The result? By the end of summer, they have an outdoor garden with selected, top-quality plants, uniform in size, quality, and harvest time, with all the advantages this entails.

This way, if you like how a particular strain performs, you can reproduce it indefinitely, both indoors and outdoors. No genetic surprises or plants that go their way. Here, everything depends on your planning. Many growers keep their mother plants throughout the year to supply their indoor crop with cuttings, and take them out to the outdoor garden when daylight hours allow. Thus, they begin their outdoor crop with plants of a considerable size, while during the summer, they maintain clones of these plants indoors that will, in turn, become new mother plants. The circle closes, and the bud jars are filled to the brim with excellent genetics. What more could you ask for?

Growing cannabis cuttings

Pests and diseases: goodbye botrytis, goodbye dramas

If you have to dance to the Gods every October to prevent botrytis from wiping out your buds… You need to grow indoors. Outdoors, pests and fungi are part of the landscape. Indoors, if you maintain clean and stable conditions, most won’t even make a splash in your grow. Whether we’re talking about small insects like whiteflies or thrips, fungi like botrytis or downy mildew, or animals like wild boars, moles, or cats (why do cats love vegging cannabis plants so much??), you can forget about the vast majority of them if you grow indoors.

Thrips? Spider mites? Sure, they can appear. But here you have complete control over eradicating them before they can do their thing, plus you can prevent them much more easily than outdoors. And best of all, you don’t have to rely on harsh chemical treatments or praying to the patron saint of plants. If you do things right, these pests won’t be a big problem, and they certainly won’t threaten your annual bud production and compromise your smoking reserves for the next 12 months.

By maintaining hygiene in your indoor grow and using a few preventative measures to help you control pests, you can forget that feeling that plagues many outdoor growers every night: Will my plants be okay tomorrow morning? Yes, they’ll be fine, just relax and keep calm.

[productes tipus=”fitxa” cat=”476″ nfitxes=”3″]

Appearance of buds: density and resin

Yes, we know, beauty isn’t everything. But let’s face it: When you see a rock-solid bud, perfectly trimmed and covered in glistening trichomes, a smile comes to your face. The controlled conditions indoors favor that catalog-ready look we love so much. And, as a bonus, they tend to have more potency and, in many cases, better flavor. It’s not just a pretty face.

Indoors, you won’t experience cloudy days, harsh rain, or having your flowers covered with dust, mud, or pet hair. They’ll have had perfect conditions for their development every day of the grow, and this is evident in both their appearance (bag appeal) and their potency.

Ideal for breeding: make your hybrids

If you’re a breeder at heart or curious about playing with phenotypes and homemade crosses, the indoor environment is the perfect laboratory for you. In this environment, you can fully control pollination, isolate male and female specimens, and preserve genetics uninterruptedly. Plus, an indoor grow allows you to perform countless tests without compromising your bud supply, which, for outdoor growers, must last a year. Can you imagine having to smoke half-pollinated weed or a cross you didn’t like in terms of flavor or effect for 12 months? More than a pleasure, it feels like a punishment!

Material for extractions: when you want to play in the top division

Resin extraction has gone from being a hobby or a way to take advantage of sugar leaves to almost an art form. And if you’re looking to extract top-quality BHO, Rosin, or hash, the indoor material makes all the difference. More resinous buds, fewer impurities, and much higher yields.

With outdoor material, you can easily extract your plants, although the plants often produce slightly less resin and, of course, are much more likely to get dirty and produce lower-quality concentrates (with more impurities) if you’re not careful and don’t wash the plant material before extracting. But if you want to compete in the resin concentrate championship, it will be much easier to do so with indoor flowers.

You see? Growing indoors isn’t about giving up the charm of outdoor cultivation. It’s about giving continuity, depth, and greater control to your passion. It’s like taking another step in your evolution as a grower, a step that also opens up dozens of possible paths.

Do you dare to turn on the lights?

The post Why grow cannabis indoors? The biggest advantages of this method appeared first on Alchimia blog.

We often get asked where to buy cannabis seeds and whether it’s safe to buy seeds online. In this guide we’ll review and recommend the seed banks we use and trust as well as teach you everything you need to know about safely and discretely buying weed seeds online.

There are several advantages to buying seeds from a quality online seed bank.

• Seeds banks offer a huge range of strains to choose from, including feminized seeds, autoflowering strains, medical strains and high THC & CBD strains.
• They ship to almost anywhere in the world.
• They offer a range of stealthy payment and shipping options to protect your privacy and allow you to stay as anonymous as possible.

We’ve personally used all of the seed banks on this list with the exception of AMS. The feedback we’ve received on their reliability and customer service means we’re confident to include them on our list.

Protecting your safety, privacy & anonymity

Is it safe to buy cannabis seeds online in the USA?

As everyone knows, the laws regarding cannabis in the United States are a complete mess. It’s illegal to possess, sell, cultivate and transport weed at the federal level, but many states have their own laws that make cannabis legal. The result of this confusion means that when you’re figuring out where to buy cannabis seeds, you won’t find reliable or reputable cannabis seed banks located within the United States. Sending seeds within the U.S. (even where weed has been legalized) is covered by federal law and the seed banks would be prosecuted.

All the seed banks we recommend are based in Europe. In the U.K. and Europe it is illegal to grow cannabis but it is legal to buy, sell and possess ungerminated cannabis seeds. We’ve never known anyone to have problems shipping seeds to the United States from Europe except for the occasional missing package.

In the extremely unlikely event that your seeds are intercepted at some point in their journey, the very worst that’s likely to happen is that your seeds are confiscated and destroyed. We can confidently say that the feds will not break down your door and you won’t end up in the big house if you order seeds online from a trusted European seed bank.

Having said that, there’s no reason not to be as discrete as possible when ordering seeds and seed banks that offer stealth packaging and anonymous payment options (e.g. bitcoin) should be at the  top of your list when considering where to buy cannabis seeds online.

We also recommend paying extra for guaranteed shipping because this means if your seeds go missing for any reason the seed bank will replace them free of charge.

If I live in a location where marijuana is illegal, is it still safe to buy seeds?

The seed banks we recommend will ship to any country in the world, but they make it very clear that you are responsible for knowing the local laws in your area. The authorities in many countries where marijuana is illegal will happily turn a blind eye and aren’t the slightest bit interested in chasing people who order a few seeds online. Other governments take cannabis possession extremely seriously and if you live in such a country you should not order seeds online for your own safety.

What’s the best way to pay for seeds to remain anonymous?

When you’re weighing up where to buy cannabis seeds, if the seed bank offers bitcoin this is a good sign that they are discrete and care about their customers privacy. Bitcoin is completely anonymous and the transaction cannot be traced back to you. Having said that, we’ve seen evidence of many people from the US, Canada, Australia, Europe and elsewhere who happily purchase seeds using their credit card and have never had an issue.

I’m still too nervous to buy weed seeds online – where else can I get them?

The main advantage of buying seeds online is that you know exactly what you’re getting. You can buy strains based on your specific requirements –  THC & CBD content, height, flowering time, medical applications and many other factors. If you don’t feel comfortable buying online for whatever reason then the best bet is to try and get seeds from someone you know. Failing that, there’s no harm in trying to grow the seeds you found in the bottom of a bag of weed!

Germination & strain selection

Will all my seeds germinate and what happens if they don’t?

Regardless of where you buy cannabis seeds, unfortunately there is no way any seed bank can guarantee that all the seeds they send you will successfully germinate. In Europe, the possession, sale and shipping of cannabis seeds is legal but germinating and cultivating them is not. For this reason, most seeds banks cover themselves by using the disclaimer that seeds are sold as ‘souvenirs’ and they won’t make any guarantees or refunds if the seeds you receive don’t germinate. However, high quality seed banks rely on satisfied customers to stay in business so you can be sure that they’ve done everything to ensure all the seeds they sell are viable. The exception is AMS that do offer a refund service and will replace any seeds that don’t successfully germinate.

In addition to having viable seeds, specific conditions are need to maximize the chance of your seeds successfully germinating. You can read our article about how to germinate weed seeds if you’d like to learn more.

If I buy feminized seeds are they guaranteed to be female?

Feminized seeds are more expensive because they have been specifically bred and treated to mature into female plants. If you look after your plants and give them the correct growing conditions, feminized seeds are 99% guaranteed to stay female. However, if your growing conditions are poor there is still a chance that feminized seeds can flip and turn into hermaphrodite or male plants.

Most seed banks also offer ‘regular’ seeds that are cheaper and come with no guarantees they will be female. In our experience, regular seeds turn out to be female around 75% of the time. If you have poor lighting or inadequate nutrient levels during your grow, you are much more likely to end up with a hermaphrodite or male plant when growing from non-feminized seeds. Weed plants turn into hermaphrodites in a last ditch effort to reproduce when they sense a poor growing environment.

What cannabis strain should I grow as a beginner?

We get asked this a lot and it’s not an easy question to answer.  In addition to how easy the strain is to grow, you also need to consider the type of high the weed will give you when you smoke it! There’s no point in spending time and effort on growing an easy strain if you end up with weed that doesn’t make you feel good.

If you’re growing indoors, the best general advice we can give is to pick an autoflowering strain that will automatically enter the flowering stage of growth at a certain age, rather than rely on you to change the lighting conditions. Other advice to make indoor growing easier is to pick a fast flowering, short strain so you don’t find your plants trying to push through the roof of your grow tent!

If you’re growing outdoors, it can be easier because you’ve got mother nature to back you up and take care of lighting and (hopefully) watering. On the downside, you have a lot less control over the growing conditions and you’re at the mercy of the weather, pests, insects and thieves. Picking a strain that’s known to be hardy and disease resistant will give you the best chance of success.

It’s also worth paying a little extra for feminized seeds because this will give you the best chance of avoiding males or hermaphrodites ruining all your hard work.

Which strain should I choose to help with my particular medical condition?

When you’re deciding where to buy cannabis seeds online, you’ll quickly learn than some seed banks do a much better job than others at helping customers find strains for medical use. For example, Seedsman has an extremely handy filter on their website that allows you to filter strains by specific medial conditions such as anxiety, depression, insomnia or muscle spasms.

If you have any doubts about whether weed can help your health issue and what strain to grow, make sure seek medical advice from a qualified medical marijuana doctor.

Legal Disclaimer

We just want to make sure it’s clear that we’re not lawyers and all the advice we’ve given here on where to buy cannabis seeds assumes that shipping, receiving, possessing or growing cannabis seeds is 100% legal in your location. If it’s not then we can’t advise you to act on this information in any way and you should campaign your representatives to change the laws and make weed legal where you live!

We’ve compiled this list of videos to help beginners master some of the skills required to grow weed. If you’re thinking about attempting your first grow, hopefully they’ll give you a visual sense of some of the steps involved to understand if you might enjoy it. Some of the videos have been around for years and others are more recent, but we learned something useful from all of them and hopefully you will too! 

The list is divided up into sections so you can skip to topics you’re interested in. Do you know any other informative videos that will help beginner growers? Let us know!

Germinating and planting seeds

Germinating and panting your weed seeds is where it all begins! There are several reliable techniques for germinating seeds and everyone has their favorite.

Planting seeds – Jorge Cervantes

Jorge Cervantes features a few times on this list of videos, and for good reason – he’s a master grower and literally wrote the book on cultivating cannabis. In this video he steps through the exact process he uses to plant germinated seeds into pots.

Nutrients & pH

Plant nutrition is a complex topic and every grower seems to have their favorite techniques, recipes and ‘secret’ nutrient formulas that will grow the biggest buds. For beginners, if you buy a quality nutrient kit and follow the feeding schedule you’ll get it right every time.

The Best Cannabis Nutrient Feeding Schedule – It’s Chronic

This guy goes uses the General Hydroponics Flora series nutrients (which we highly recommend) but abandons the feeding schedule in favor of his own recipe.

There are a bunch of other schools that offer similar programs such as THC University, Clover Leaf University and Oaksterdam University which actually has a physical campus.

General Blogs & Online Stores

These sites are all great but if you’re specifically interested in learning how to grow weed they probably add the least value because they’re focused on a wider range of topics or on eCommerce. However, many of them have good sections on growing where you can find useful information.

Cannabis Now

Visit Site

Cannabis Now is both a bi-monthly print publication and a website. They focus a lot on industry news and culture but they also have a cannabis cultivation section that contains some good content on growing cannabis. Because they’re more a traditional blog it’s harder to find posts on specific subjects but the search functionality works pretty well and they use some useful tags like how to grow marijuana.

Dutch Passion Seed Company

Leafly is a big (and ridiculously profitable) site that focuses on strain reviews and dispensaries. They also have a cannabis 101 section on the site that has heaps of articles for beginners on many topics, including growing. Unfortunately there’s no tags or categories specific to growing but once again if you use search you’ll find some articles worth reading.

Royal Queen Seeds

Visit Site

Royal Queen Seeds is a popular European seed bank and the growing cannabis section of their blog has some really well written content. The only issue we had is that the search functionality seems to favor products rather than articles (understandable as they are an online store) so finding specific information is a bit harder.

Seedsman

Seedsman is another online seed bank and the cultivation section of their blog has some good articles on growing cannabis. None of the posts go particularly in-depth but the amount of content means you’ll certainly learn something interesting if you search around.
