An old joke in physics is that of the “spherical cow”, poking fun at some of the assumptions physicists make when tackling a new problem. Making the problem simple like this can help make its fundamentals easier to understand, but when applying these assumptions to real-world problems these assumptions are quickly challenged. Which is what happened when [Seth] from Berm Peak attempted to tow a huge trailer with a bicycle — while in theory the bike just needs a big enough gear ratio he quickly found other problems with this setup that had to be solved.
[Seth] decided on a tandem bike for this build. Not only does the second rider add power, but the longer wheelbase makes it less likely that the tongue weight of the trailer will lift the front wheel off the ground. It was modified with a Class 3 trailer hitch, as well as a battery to activate the electric trailer brakes in case of an emergency. But after hooking the trailer up the first time the problems started cropping up. At such a high gear ratio the bike is very slow and hard to keep on a straight line. Some large, custom training wheels were added between the riders to keep it stable, but even then the huge weight still caused problems with the chain and even damaged the bike’s freehub at one point.
Eventually, though, [Berm Peak] was able to flat tow a Ford F-150 Lightning pulling a trailer a few yards up a hill, at least demonstrating this proof of concept. It might be the absolute most a bicycle can tow without help from an electric motor, although real-world applications for something like this are likely a bit limited. He’s been doing some other bicycle-based projects with more utility lately, including a few where he brings abandoned rental e-bikes back to life by removing proprietary components.
In cannabis cultivation, achieving truly exceptional harvests doesn’t depend only on large buds or high THC percentages. True quality comes from understanding how the plant responds to its environment and applying techniques that enhance its natural physiology. Among these practices, one stands out for its simplicity and effectiveness: controlled water stress. Far from being a trend, it is a science-backed strategy that allows growers to increase resin production, intensify aromas and enhance the metabolite profile without adding extra products or complicating the grow. In this article, we explore what it is, how it works and how to apply it correctly to take your flowers to the next level.

Although its name may sound harsh, its mechanism is based on a simple principle: when the plant senses that water is scarce, it activates defence mechanisms that increase the production of trichomes and secondary metabolites. This reaction is not exclusive to cannabis. Many aromatic and medicinal crops, such as lavender, rosemary, thyme, sage or even grapevine, respond in a similar way. In all of them, a moderate water deficit enhances aroma, essential oil concentration and, in the case of grapes, sugar levels (alcohol).
[productes tipus=”fitxa” cat=”143″ nfitxes=”3″]
Controlled water stress is a method applied during the final stage of flowering and consists essentially of temporarily reducing irrigation frequency. The goal is to trigger a mild physiological discomfort that activates metabolic pathways associated with defence. When roots detect reduced water availability, the plant produces abscisic acid (ABA), a hormone that instructs stomata to partially close to prevent moisture loss. This small shift alters the plant’s internal dynamics: photosynthesis decreases slightly, primary processes slow down and activity in secondary pathways increases, including the synthesis of terpenes, flavonoids and cannabinoids.
The result is often visible: greater resin density, more defined aromas and more uniform ripening. But to reach that point, the process must be applied in a controlled way, without pushing the plant into extreme drought.
We now know that this mechanism is supported by scientific research. A study by Caplan et al. (University of Guelph, 2019) applied a water deficit during late flowering and recorded a 12–13% increase in THCA and CBDA, together with a 67% increase in total cannabinoids per cultivated area. These results were especially notable because there was no loss of biomass.
Recent reviews, such as the one published in Horticulturae by Sharma et al. (2025), compile multiple trials showing a clear pattern: mild, late water deficit stimulates secondary metabolite production as long as it is kept within safe limits. However, when stress is excessive or applied too early, the effects can be negative: reduced trichomes, oxidative stress, loss of vigour or greater susceptibility to pathogens. In other words, water stress works — but it requires precision and constant observation.
Water stress should only be applied when the flowers are already formed and beginning their ripening phase. For most photoperiod strains, this occurs between the 6th and 8th week of flowering. Applying it earlier may stress the root system, reduce final bud size and make plants more vulnerable to pests like mites, which quickly take advantage of weakened tissues.
You shouldn’t stop watering abruptly. The correct approach is to slowly space out irrigation: if you water every two days, switch to every three or four; if you water twice a week, reduce to once or one and a half, depending on pot size. What matters is allowing the substrate to dry more than usual, while never letting it dry out completely.
The plant will give clear signs: slightly drooping leaves during the warmest part of the day indicate the right stress level. In contrast, general wilting, soft stems or burnt tips mean the stress is too strong. After watering, the plant should recover within a few hours — this rebound signals proper management.
Controlled water stress works best when applied in gentle cycles: a period of mild dryness followed by recovery. Typically, this pattern is repeated two or three times during the last weeks of flowering. In fully controlled indoor environments (stable climate, good airflow), some advanced growers leave 10–12 days without watering right before root flushing.
When done correctly, this method produces denser flowers, with less internal moisture and higher trichome concentration.
When the process is executed correctly, the changes are noticeable. The increase in trichome production is often the most obvious effect. This increase is not only visual but chemical: greater concentration of essential oils and cannabinoids. The aromatic profile also changes. Volatile terpenes such as myrcene, limonene, pinene or linalool express themselves more intensely. This results in a more pronounced fragrance at harvest and a stronger flavour after curing.
Another clear benefit is the reduced risk of Botrytis. Flowers with lower internal moisture are less likely to develop mould, especially in dense-bud varieties or humid climates.
It’s important to highlight that water stress does not always increase the final yield. That is not its purpose. What it consistently improves is overall quality: more density, more resin, stronger aroma and a much more professional finish.
Although the technique is simple, it is not risk-free. The most common mistake is taking drought too far. When the substrate dries out completely, roots can be damaged, leaves may show necrosis and the plant may enter a stress cycle that provides no benefit.
Dried cannabis plant
Another mistake is applying it at the wrong moment: during growth, preflowering or when flowers are still small. In these phases, the plant prioritizes basic structures: roots, stems, leaves and calyx formation. Interrupting that process can reduce final yield.
High temperatures can also amplify the damage caused by water deficit. With less water, the plant has a reduced ability to regulate its internal temperature. In warm environments, maintaining correct VPD and strong ventilation is essential.
An interesting ally in these situations is silicon. This element strengthens cell walls, improves tolerance to abiotic stress and reduces vulnerability to pests. At Alchimia, we recommend products such as Biotabs Silicium Flash or Atami B’Cuzz Silic Boost to support this type of technique.
Controlled water stress is part of precision cultivation, where the goal is not to harvest more but to harvest better. It resembles what happens in viticulture: before harvest, winegrowers prefer dry weather, since excess water dilutes grape aromas and reduces sugar concentration (alcohol). In the same way, a cannabis plant with limited water availability concentrates more resin and terpenes.
Moreover, when combined with complementary techniques such as night-time temperature drop, use of natural biostimulants, VPD control or strategic pruning, water stress acts as a final enhancer that allows the plant to express its full genetic potential. Among the most widely used natural biostimulants are Aptus All-in-One Pellet and C02 Effect Led Nano, valued for supporting metabolic processes without saturating the substrate.

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!
Avoiding mistakes will help us get off to a good start
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″]
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.
Lighting and air renewal are key to getting good results
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″]
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.
A professional substrate guarantees a good start for the plants
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.
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.
Correct watering is essential to a bountiful harvest
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!).
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″]
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.
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.
Maintaining mother plants over summer can be complicated due to the heat
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!

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.
In summer, LED panels are an excellent alternative to discharge lamps
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 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!
Correctly adjusted temperature and humidity levels will encourage the plants’ development
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.
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).
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!
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.
Pests such as spider mites and white flies appear 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.
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:
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!

If you’ve ever dreamed of an indoor grow that manages itself—no cables, no nasty surprises, and no spending half your life adjusting fans—the solution has a name: AC Infinity. 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.
AC Infinity devices are as efficient as they are elegant in design
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″]
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.
You can connect up to 4 devices to the controller, such as lights, air extractor, fan, and humidifier
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.
With AC Infinity, controlling the crop climate is very simple
