Micro grow guide

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.

It might not come as a surprise that not every strain is equally suited to be grown in small spaces. Most sativa or sativa-dominant strains simply grow too tall to be used in a micro-grow setting. They often stretch 2-3x their size during bloom, reaching upwards of 3m in some instances.

Maximising Bud Size – Growing Cannabis Indoors and Out
Depending on the relative humidity of your micro-grow space, your plants may require more watering than they would regularly. Although you should still take care not to overwater, don’t be surprised if your plant’s need for moisture is elevated. Given that most micro-growers crop indica or indica-dominant hybrids, the plants will likely become bushy and compact. Make sure you are able to easily water your plants by pruning or training as necessary. More on that later.

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!

Micro-growing is a way for cultivators to crop high-quality bud in tight spaces. But how is it done?

Micro grow guide

Ideally, you’ll want to water your mini weed plants from the bottom, allowing the soil and root system to take up as much, or as little, water as it needs. This also prevents nasty chemicals or fungus/bacterial spores that your plants don’t want from cascading down into your soil. Top down watering essentially forces your plant to uptake anything that’s in your water- chlorine, rust, fluoride, and other less than plant friendly nutrients- whether it wants them or not. Because you’re using a micro-grow set up, your plant is going to need a rash of water. Keeping your little baby hydrated without drowning it can be a delicate balance, but bottom up watering systems can help to keep your plant properly watered. Hydroponic systems are a great choice for growers who have a bit more space, time, money, and expertise, but can be a bit intimidating for new growers or those with severely limited space.

Earth, Air, Fire, Water

  • 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.
  • HPS/HPI
    • 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.
  • LED
    • 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.

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.
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.
All Method, No Madness
Lighting and heat go hand in hand when it comes to growing a mini marijuana crop. Because of the small space, combined with your plants near constant need of light, heat can build up super quickly if you’re not careful about what type of light you use. While lighting setups range from the super cheap to the hellaciously expensive, there are a few types of bulbs that are absolutely necessary to have. Depending on how much cash you want to put into your setup, you may need to get a few different types of bulbs to shine on your plant at different stages of growing. Any bulb you use needs to produce at least 400W of light energy.
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:

Starting out your crop, you’re going to need to pay special attention to both growing space and soil quality. If you’re looking at creating a good quality plant with a decent output of buds, you’ll have to consider the root space that any given plant will need. Cannabis plant come in roughly two main varieties: Indica and Sativa. Sativa plants are notorious for growing tall, leggy output, while Indica’s tend to produce a smaller, bushier plant. Indica’s work really well for small space growing. They’re also a bit heartier, so they’re a great first choice of crop to get your green thumb confidence up.
