In order to grow, a cannabis plant needs light, air and water. So however small the cabinet, a lamp must be present for light and heat. A lamp timer is also essential to activate the flowering phase, by switching from 18 to 12 hours of light per day (does not apply to autoflowers). The light source can’t be too large or have too much wattage. A high wattage creates too much heat in a small grow room. Be sure to hang a thermostat in the grow room. Fluorescent, CFL (energy saving lamps), HPI and HPS lamps with a very low wattage and LED bulbs are particularly popular with micro growers.
Much can be written about LED lighting. For this article, it suffices to know that LED is ideal for all light colours. It takes up little space and is not very hot, so plants can be placed close to it. However, good LED grow lights are expensive and therefore not as cost-effective for micro growing.
approx. 0.5 litre: plant height of up to 13 centimetres
HPI- and HPS lamps have been favoured by indoor growers for years. That’s because they have a high light output. You can use these conventional grow lights in micro growing spaces as well, but it is not ideal. The lower wattages are harder to find and they tend to become very hot. As a result, the plants can’t be placed too close to the lamps. This requires space, which is precisely what you don’t have with micro growing.
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.
Fluorescent tubes are inexpensive, have a good light output and their shape allows them to spread the light well. Also, fluorescent lighting is available in different light colours. A growing plant requires more blue light while a flowering plant requires more red light. Neutral light and warm white are common colours with fluorescent lamps and meet this need.

The only way to be 100% sure about the origin and quality of cannabis is to grow it yourself. But not everyone has enough space or budget to set up a good grow room. And if growing outside is not an option due to an unfavourable climate, because your neighbours won’t tolerate it or because the law doesn’t allow it, you are totally dependent on others. Fortunately, the cannabis plant provides you with more options than you think. What about micro growing?
With topping, you cut or trim the highest shoot off the main stem. This stimulates the plant to create two new shoots. Instead of a single shoot growing vertically, there are now two growing horizontally. Extra buds also grow on the second shoot, which means more yield.
Achieving the biggest possible harvest in the smallest possible grow room; that's essentially what micro growing is about. Read all about micro growing.
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.
• 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.
Flushing Your Cannabis Plants
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.
Airflow is important to all cannabis cultivators, but especially so for micro-growers. One of the best ways to achieve healthy air circulation in very small grow-ops is to use computer fans. These are small and silent, and easy to set up.
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.
In addition to the above, there are numerous other requirements growers must consider like nutrient feeding and pest/disease control. Hopefully, this article gave you a solid foundation on the logistics and tips surrounding a successful micro cannabis grow. Now, it’s up to you to conduct further research and get growing!
A Guide On Properly Drying And Curing Your Cannabis Flower
Because micro-grow operations are usually conducted in very small spaces – think closets and tiny spare rooms – it is very important to cultivate with the goal of keeping things as simple and compact as possible. This, of course, is easier said than done. With this guide, however, we hope to provide general tips on maximising the variables that go into micro-growing.
Micro-growing is a way for cultivators to crop high-quality bud in tight spaces. But how is it done?
