A more aggressive method, high-stress training increases cola sites through topping or super cropping to promote an even canopy and increased cola sites.
With a limited space, you can also train your cannabis plants to increase yields. Some effective methods include:
A grow space can be as small as a 2’ x 2’ x 4’ grow tent or as big as a warehouse, but they all have a number of things in common.
Train Your Plants
LEDs are changing the game for small-space growing by providing quality full-spectrum light with minimal heat. This allows plants to grow closer to the light source without damage from heat, while also reducing the need for climate-control equipment to bring down the temperature in your grow. It should be noted that LEDs can still burn your plants, but there is less of a risk than with older lights.
Be sure to include enough soil in your pots to prevent roots from getting bound. Frequently check to see if roots are exposed. If you see them coming out of the drainage holes at the bottom of the pot, it’s time to transplant it to a bigger pot.
Don’t Burn the Plants
Sativas, indicas, and hybrids all grow differently. Sativas are known for their lanky growth and more open bud structure, while indicas tend to grow short and stocky and have denser buds. Hybrids can have traits from both.
Keep in mind that this is a generalization of strains—some indicas grow tall, and some sativas grow short. Be sure to check out Leafly’s strain explorer for growing tips on specific strains.
If you’re only looking to grow a shorter plant that maxes out at two feet, you’ll need about a gallon sized pot. If you’re growing anything larger than that, you’ll need to start with a two to five gallon pot. As a pro-tip, while circular pots are more widely used and widely available (especially if you’re looking at a paint bucket set up), square pots will help you conserve space.
Once your weed plants are distanced, then it’s time to look at the other important factors mentioned above in your grow room space. Buy grow containers that will fit your room, adjust your plants so that they’re getting enough light on all sides, and be sure that there is enough room for a gentle but steady airflow throughout each plant from top to bottom. Once you meet all these requirements to keep every cannabis plant in your grow happy and healthy, that is your ideal distance to space your plants.
Grow Containers and Pots
The light should be able to shine through from the top to the bottom of each cannabis plant’s perimeter, as well as on all sides. If a majority of the plant is being shaded, it will harm the plant’s development. This will lead to less potent trichomes and less buds being grown overall, and can stunt your plant’s growth or leave it vulnerable to disease. If you find some of your plants are stuck in the shade, it’s time to separate your plants even further from each other.
Your lighting set up in your grow room space will also have a big impact on how far apart your weed plants are, since your goal is to get as much of that artificial sun on every part of your plants as possible. The first thing to watch out for with your grow room lighting is what type of reflectors or hoods are on the appliance. If the hood is at too narrow of an angle, the bulbs are too deep set in the frame, or the reflective material is cheap, you’re losing a lot of available light while simultaneously wasting a lot of energy.
How much space should be between cannabis plants?
If you’ve correctly distanced your weed plants, there should be enough direct light shining through the canopy to illuminate most of the plant’s leaves.
