Hello, I plan to grow 10 plants in 10m2 to 21m2, 2.8m height but havent`t decided on the seeds yet. There is going to be a good amount of light, 2 HPS lamps of 600W are enough I think. What indoor plants with high amount of THC have the biggest yields and are not hard to grow, I am a beginner yet. Are there some nutrients that I need to use in the vegetative stage? Thanks a lot, I would really appreciate your help!
