Hey, buddy! 👋
For the ideal development of one feminized plant during the vegetative and flowering stages (without training, without pruning, without frequent defoliation or no defoliation at all), you need 1 square meter of space to achieve the yield statistics from your seed bank with one plant. In 1m^2, the plant will form excellently and won't require extra attention, except for watering and lighting!
You can grow about 3-4 autoflower girls in 1m^2 with a limited vegetative period. I admit, you can grow more, from 10 to 12 in 1m^2, using SoG while applying SCROG, defoliation, a 12/12 light schedule from germination (in the case of feminized), and controlling the lighting in all areas of the considered space.
I grow in a 0.36m^2 tent with a height of 1.8m, one plant in a 20-30 liter pot. The results are in the diaries. 👌
Good luck, buddy!
