how many plants can i grow with a 600 watts HPS? The space will be 3' wide 6' long and 6' high. Also what a good guess on how much a single plant can yeild? Sorry i am just really really new to the whole growing thing
Read up! Average is 6 plants. Yield depends on soooo many variables. However since this is your first, if your successful chances are 6 would be plenty.
