Depending on the diameter of your pots, several can fit into one square metre. But the size of your containers doesn’t just impact how many plants can fit per square metre, but also how big the plants will get overall. Said differently: The larger your pots, the bigger your plants will get.
Before you get started with your indoor grow operation, you need to have a plan. Among the things you need to think about is how many cannabis plants you can feasibly fit in your grow space.
• 4–16 plants per square metre
• Outcomes: Fast yield, keeps plants short, easy to perform, comparatively smaller yields per plant
You can choose how many plants/pots you use for a ScrOG. You could fill your space with only one monstrous plant in a large 20l pot, but you could also grow several smaller plants, such as four medium-sized plants each in a 10l pot.
When using CFLs, divide by 150. For example, using a 400W CFL: 400W ÷ 150 = 2.6 or 3 plants
In a SOG, plants only get 1–2 weeks of vegetative growth before they are forced to switch to flowering. No pruning or training is needed. As the plants don’t have time to branch out, the result is many short plants with short main colas.
• 5 litres: Plant height up to 60cm
• 11 litres and more: Average plant height (check strain description)
As an example, if you just want to grow a single untrained photoperiod indica plant, a 1 × 1m tent should be sufficient. As you add more plants, you’ll need to scale up accordingly. But again, don’t just account for the eventual size of the plants themselves, but also lighting, ventilation, and other equipment.
Topping and fimming are high-stress training methods. By cutting off or pinching the main growing tip, you break the apical dominance of a plant so it develops multiple main colas instead of just one. This naturally results in bushier growth and causes plants to stop growing in their characteristic Christmas tree shape.
