In micro growing spaces, you should ideally opt for an Indica-dominant strain, such as our Northern Lights or Hindu Kush. Indicas remain smaller compared to Sativas. The length of an Indica also increases by 50 to 100% during the flowering phase, while Sativas undergo a 200 to 300% increase in height. So if the flowering of an Indica is activated once it has reached the middle of the growing space, it is likely that it will finish just below the ceiling.
approx. 12 litres or more: average plant height
FIM stands for “Fuck, I missed.” The story goes that someone didn’t properly perform the topping technique and cut off the shoot too high up. When this technique is performed correctly, new branches grow in addition to the two new shoots, which generate more yield.
The advantage of indoor cannabis cultivation is the ability to monitor the growing process. In a grow room, almost all circumstances can be optimised. This allows the cannabis plant to grow and flower in a perfect environment. Obviously, out in the open a plant can become quite large, because a pot hinders root formation. But at the same time you have no control over the climate outside, while you do inside. Inside, you have complete control over the light, temperature, air circulation and humidity, and of course water and nutrition. These ideal conditions are essential for a healthy plant and also for a decent yield.
Three techniques that affect the size of the plant are topping, FIM and super cropping. With these techniques, you can influence the height of the plant to create more of a bush-like shape.
Energy-saving lamps are almost the same as fluorescent lamps. There are a few major differences. The VSAs are built in and the glass of the lamp is folded. The range of light colours is also limited.
approx. 0.5 litre: plant height of up to 13 centimetres
But there are more tricks available to affect the size of the plant. Most plants and trees have just as much volume under the ground as above the ground. This also applies to the cannabis plant: the amount of soil which the plants have at their disposal has a large influence on their size. The available space for soil is limited with micro growing, but below is a list of averages to give an impression:
approx. 5 litres: plant height of up to 60 centimetres
Achieving the biggest possible harvest in the smallest possible grow room; that's essentially what micro growing is about. Read all about micro growing.
Training techniques are used by cultivators to limit the height and/or increase the yield potential of their plants. A method that is used a lot in cannabis grows is topping. Topping involves cutting off the main stem so two new main colas will form instead of one. This allows not only for bushier plants capable of producing denser, higher-quality colas, but also limits the height significantly. Topping can be done as soon as the plant has 4-6 nodes or three pairs of fully formed leaves. Topping can be done during the vegetative stage of growth, but should not be conducted during flowering.
Another technique that can help control height is ScrOG or screen of green. This method involves tying down and weaving new growth beneath a screen that keeps plants at a certain height. This will force the plant to grow more horizontally, giving the buds more light exposure and thus, potentially boosting yield.
How To Dry And Cure Your Cannabis
• LED: LED lighting is becoming better and more popular every year, and is a very suitable solution to our heating problem. It has a wide light spectrum, able to generate all the colours HPS and CFL can, but it generates very little heat in the process. LED lighting does come with an issue, however; it can be quite expensive outright. This might not be the solution if you are looking to build your cannabis growing space on a tight budget.
Place an exhaust fan near the top of your grow space, and leave an opening in the lower end. The hot air generated by the lights will rise and be ejected by the exhaust fan. This allows new, fresh, cool, and CO₂-rich air to flow in. For extra cooling, install an intake fan at the bottom of your space to make the process more streamlined. For stealth grows, it’s usually important to install a carbon filter, which neutralises the odours formed during the bloom phase.
Micro-growing is the optimal solution for growers with limited space and resources to facilitate a successful cannabis grow. By optimising several necessary variables, you can crop impressive buds in spaces as small as a cabinet.
Lighting is a crucial element in any cannabis grow, and there is a lot of debate surrounding which lights are most ideal for each kind of operation. The most potent lighting system is the obvious choice, but it isn’t ideal in all cases. For a micro-grow, excess heat and light too close to the canopy can seriously damage your plants. It just so happens that the most powerful lighting systems also usually produce a lot of heat.
While some of this heat can be mitigated with proper cooling and venting practices, this also has its limitations. As a result, micro-growers are largely limited in what they can use. Here’s a breakdown of the most popular lighting systems.
Your choice of soil is also quite important. It should be rich and drain well. Anything with a muddy or clay texture is a no-go. One consideration, especially for smaller operations, is the actual amount of soil used. Large containers will obviously take up too much space and may make it harder to light your plants. At the same time, tiny containers will stunt growth and make your plants rootbound. When looking to achieve “normal height” plants, you’ll want a 12l container. If you want to contain growth, 5l will limit height to around 60cm while 2-3l will allow the plant to only reach 24cm. It’s all about your exact limitations, strain, etc. Square containers take up less space than round pots. Low and broad containers are often a good fit for most indoor micro-grow environments.
As cannabis is moving more and more into the mainstream domain, more and more novice cultivators are looking into cropping their own cannabis plants. Few individuals have the large space requirements and breadth of knowledge to set up a full-sized grow. “Micro” means small, and micro-growing involves cultivating few cannabis plants in environments with major spatial and resource limitations. The process of micro-growing is perfect for new growers looking to experiment with home cultivation, without wasting money and time on a crop that may never come to fruition. In short, micro-growing is the predominant way growers find out if the process is right for them.
Micro-growing is a way for cultivators to crop high-quality bud in tight spaces. But how is it done?
