Light spectrum – Grow lights with more blue in the spectrum tend to keep plants short, while grow lights with more red can encourage stretching. LEDs or bulbs labeled with a spectrum of 4000k, 5000k, and 6500k are great choices with plenty of blue to keep plants short.

LED grow lights come in a variety of shapes and sizes, so they can fit almost any setup. LEDs tend to be low on heat and electricity usage, which makes them great for small stealthy gardens. LED yields are excellent, too. On average, LEDs produce about twice the amount of dried flower as fluorescent lights like CFLs and T5s for the same electricity. The newer models of LEDs can yield even more. How to grow with LEDs in a mini tent.

Quick Summary (how to keep plants small without sacrificing yields)

Do you want to grow tiny cannabis plants? Would you like to build a “microgrowery” for your marijuana garden? This tiny plant tutorial will teach you how to grow cannabis plants that stay small yet still produce an abundance of weed! I’ve grown a lot of cannabis plants of all sizes, and I’ll share the most helpful tips and tricks to make cannabis plants grow in the exact shape and size you want.

Grow tents are easy to set up (usually requiring one or two people to install) and just as easy to take down, making them the stealthiest choice for someone who may have a landlord or a meter reader to fool every once in a while. All of them come with holes for outtake fans and secure poles from which to hang your grow lights. Some even have separate chambers for vegetative growth and cloning, making them perfect for people living in one-bedroom apartments or studios with limited space to grow.

When pruning, start early and do it often. Cut or pinch branches just above the node, where two new shoots will emerge. If you stay on top of this process, you’ll have plants that look like bonsai bushes, with plenty of bud sites but not a lot of stretching or big gaps between the nodes. This is the most efficient way to get bigger yields out of small spaces, but your plants’ vegetating time will increase, so factor that into your schedule.

Growing pot in small spaces doesn’t have to be an exercise in futility. Danny Danko breaks down the ins and outs for cultivating cannabis in closets, growboxes and tents.

Growing in closets is convenient and stealthy as long as you’re able to move the air in and out without arousing suspicion. This might require venting spent air through a hole in the wall inside the closet rather than running curious-looking tubing in and out.


A trellis system constructed from chicken wire at the canopy level (a.k.a. the ScrOG or screen of green” system) will further spread out bud sites and increase your yields considerably. Simply train growing shoots to grow horizontally along the bottom of the screen to fill out empty spots.

A small oscillating fan is another requirement for your micro-grow. Place it at the canopy level in order to keep air moving and avoid stagnation. A good rule of thumb is that if your leaves are always slightly moving, you have good airflow in your garden. If not, add more fans until you see a gentle breeze stirring the leaves.

A 3′ x 3′ closet is perfect for a 400-watt light, but look for one with some sort of air-cooling technology that removes heat directly from the sealed, glassed-in hood. Lights with open hoods produce too much heat in small spaces, and you’ll quickly find that your temps at canopy level are too high to sustain explosive plant growth.

No Limits

Another great investment for people looking to produce their own pot are growboxes. These come in a variety of sizes and prices based on how much functionality they provide. Some are simply metal cabinets with doors and a fan attached, while other, more expensive units use touchscreen technology and computer chips that run virtually every aspect of the grow, from CO2 injection and lighting timers to hydroponic feeding regimens and intake/outtake fans. The better ones can also roll on casters, making them easier to move around an apartment or garage.

When using HIDs, a minimum of 50 watts (or 6,000 lumens) per square foot is necessary to maximize marijuana bud production without creating too much heat. A 250-watt HPS light and reflector are perfect for a 2′ x 2′ space. Avoid the overkill of using a 1,000-watt light in a small space and you won’t have to deal with the headache of trying to remove all that built-up hot air. For micro-systems such as a small cabinet, there are even smaller-wattage HPS lights that work perfectly to produce buds without creating too much heat.
