Naturally, the smaller the pot, the more frequently you need to water your plant. That’s why your best bet is to use some basic automatic drip system.

Week 13. Mature colas and a macro shot of trichomes.

After long spring days outdoors, the light schedule in the tent was 22/2 for the whole of the vegetative phase, then, in week 9, the grower started to reduce light hours a couple of hours at a time. And starting from week 10, it was 12/12 till the end of the flowering stage which lasted 8 weeks.

Week 2. The seedling tied down with a garden wire.

Strong Genetics and Subpar Conditions

The Ambient Q30 grow tent and the Zkittlez seedling in week 1.

The grower martiniii had to keep his Zkittlez Auto small for this micro grow, so he fimmed and then topped his autoflower and performed a lot of LST and defoliation. The guy was learning on the go, and there was some loss of bud due to mold, but overall the plant performed quite well.

This grow started outdoors, and in week 4 the plant was rather lanky and had long internodes. (Low outdoor temperatures often have this effect.) The little plant was transferred indoors in week 5 and began to receive training right away. The goal was to keep the canopy flat and all the colas at the same distance from the light (a 100W LED). Besides LST, the gardener performed only very light defoliation, plucking some old leaves in the bottom part. Otherwise, he preferred the leaves to senesce and fall off on their own.

He used a very small (4-liter/1.06-gallon) plastic pot filled with soil with some coarse perlite mixed in and had to water every day. It was very inconvenient to do manually, so in flower, he installed an automatic drip system.

It can’t be understated how crucial lighting is to growing robust cannabis plants, and this may be one of the toughest challenges of a micro grow. Excess heat from bulbs that are too close to the canopy can damage your plants, and depending on the space, bulbs can generate a lot of heat.

When you grow in a smaller pot, not only will you have to water more frequently, you will have to figure out the appropriate nutrient dose, because nutrient burn can kill your plants. Most nutrient bottles are geared toward much larger grow rooms, so you’ll have to do a little math to get the dosing right.

Whether you decide to cultivate in a closet, homemade grow box, or a cupboard, cannabis plants still demand certain conditions to grow into healthy adult plants. To have a successful small harvest, you won’t need to buy the newest or fanciest equipment, but you will definitely need some basics.

Final Thoughts

Otherwise, you could utilize the scrog technique, aka the screen of green, which is a trellis net that is placed on top of plants. The scrog helps to open the branches for airflow and controls the height of your plant.

To keep your plant within its grow space, you will have to do some plant training. There are a few techniques, but some are more accessible to novice growers than others. If you are an experienced cultivator, using high-stress training techniques like topping or firming could work well.

If you’d rather keep the dank scent certain to emanate from your grow on the down-low, consider installing a carbon filter, which can neutralize the smells that come along in the bloom phase.

For small space grows, it’s recommended to use LED lights because they have the wide light spectrum required for cannabis, and they generate very little heat. However, LEDs can be a very expensive upfront cost.

Healthy air circulation is a key component of a micro cannabis grow. A couple of solutions to create regular intervals of air exchange is to leave a door open (but watch out for the smell) or holes in the space to encourage regular airflow. Another idea is to use a computer fan near the top of your grow space so it’s not blowing directly on the canopy.
