Hi.. Its not so much the number of plants because this depends on strain,veg time and other variables. With a 400 you can grow nicely in a 3x3 space. I hope this makes sense... I recommend growing fewer plants with longer veg times for higher yields, If youve got the patience... Sometimes I dont.. d:rastasmoke:
dlovejah Reviewed by dlovejah on . Optimal # of plants for a 400w HPS/MH light I just purchased this light on ebay for 200. I was wondering if anyone can tell me how many plants i should try and grow for optimal production with this type of light. I want quality over quanity to maximize my yields. Would 6 plants be to much? Rating: 5
