Enter micro-growing. Micro growing is essentially growing your own weed without the hassle and expense of having a giant crop. Micro-growing is hugely beneficial for home growers and novice plant aficionados. Most plants that are capable of growing in a micro climate, and still producing quality buds, require less water, less space, less light, and are all together just easier to grow. But there are a few things you’ll need to know to get your cannabis from seed to weed.
As above, so below: Plants have a tendency to produce roots in roughly the same proportion that they produce plant- so if you have a large, bushy, green thing poking out of your soil- it’s going to need a bunch of root space. Rule of thumb for plant size to pot volume is:
While this isn’t a hard and fast rule, putting your large plant into a small pot can cause the roots to overgrow their space and become “root bound”, or create too many roots and not leave enough space for soil, nutrients, and water. In a micro-grow setting, the plant will need a higher amount of both fertilizer and food. Knowing what kind of fertilizer, and how much you apply, depends greatly on the specific strain of plant you’re using.
No, this isn’t a line from The Craft, these are legitimately all of the things you’ll have to take into consideration when growing your own bud. Tiny crop or full sized, you’ll have to consider each and every one of these elements and tailor them to your plant. Don’t worry- it’s not witchcraft, just good gardening guidelines.
- Fluorescent tubes/CFL
- Fluorescent tubes and CFL (Compact Fluorescent Lighting) are fantastic and relatively cheap options when using a micro-grow setup. They don’t produce much heat, and they offer an excellent light output. But these lamps aren’t generally broad spectrum, so you’ll need to have a variety to suit your plants growth cycle. Vegetative plants require more blue light, while flowering plants need the red.
- High Pressure Sodium (HPS) and High Wattage Metal Halide (HPI) are great for bigger growing ops, because they’re lightweight, inexpensive, and let off a load of light. However, they also let off a ton of heat, so they’re not ideal for micro-growing operations as they tend to dangerously dry out plants.
- Light Emitting Diode (LED) lamps are superb for micro growing conditions because they are compact, let of virtually no heat, and they offer plants a wide light spectrum- suitable for your plant throughout it’s growth cycle. The main setback for micro growers when considering LED lamps is their price tag. LED grow lamp set ups are incredibly expensive, but some argue very worth the price.
Start your plant off right by planting it in good quality soil with a mix of perlite, vermiculite, compost, and coconut shavings. The perlite and vermiculite will help to keep your soil “friable” or crumbly, and stop it from becoming a brick if it dries out. They both help to absorb water which is great, as cannabis plants need a ton of it. Compost gets the the soil filled with nutrients early. If you don’t have your own compost, commercial options are available. You can also use cow, sheep, or even bat poop for fertilizer. Worm castings, fish meal, wood ash, and even human urine are all ways that more experienced gardeners use to fertilize their plants. These are great if you want to get into the more technical side of growing, but if you don’t want to have to concern yourself with specific nutrients and pH balance of your soil, commercial liquid fertilizers are the way to go. Coconut shavings give the soil good drainage and add to friability. Keeping your roots from becoming waterlogged.
All Method, No Madness
All marijuana plants need a free flowing breeze. This not only helps to create healthy and strong stems (with which to hold all of those luscious, massive buds you will be growing) but also helps to circulate in CO2 rich air. Your plant will need a ton of CO2 (the stuff we breathe out and plants breathe in) to grow healthy, even for a small marijuana plant. Plants use CO2 to go through photosynthesis and create new cells, so they will quickly process CO2 out of stale air. This is why it’s paramount that any crop big or small, has new, CO2 laden air being pumped into their growing space. A fan set up will not only give your plant plenty of CO2 to breathe, but it also helps to remove heated air from lighting sources, which is super important if you don’t want your plant to dry out too quickly. Most mini weed plant growers use a simple two fan system. This system is cheap and easy to come by as the best way to achieve it is by using a computer fan set up. Two fans can be placed in the entrance to your grow hut: one up as high as your grow space will allow, the other down a bit lower near soil height. The lower fan will blow cool, CO2 rich air into the setup, putting (good) stress on the stems, and cooling down your grow space. The second, higher, fan will suck out the CO2 poor air as well as the heat (heat rises). Many growers choose to attach some kind of air filter onto the intake side of the lower fan, which will help prevent pests and spores that could potentially harm your plants health. If you’re worried about the stank from your little bundle of joy, attach a filter onto the intake side of the higher fan as well.
Micro growing is essentially growing your own weed without the hassle and expense of having a giant crop. Here’s everything you need to know to produce your own!
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.
Although cannabis normalisation and legalisation are gaining momentum around the world, finding clean, good quality cannabis is not always easy. This is a pity, because good quality is very important for health purposes, especially for medicinal use.
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.
Micro growing is more or less the same as regular indoor growing. There is only one major limiting factor: the available space. Which is much smaller. Really a lot smaller! Examples include a computer cabinet, an old speaker case or a small home-made grow box. The challenge is to create the optimum conditions in which to grow as many plants as possible in that small space. Or to allow one single plant to grow to its maximum size, within the limits of the micro growing space.

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.
A good alternative is autoflowers. Whatever the conditions, these strains remain smaller. These plants, moreover, are not sensitive to the number of light hours to activate the flowering phase. They can be placed in 18 hours of light per day for the entire cycle.
