I'm going to do a 2 plant hydroponic setup in a large spare closet but I do not know how strong of a light would be best. I've considered a 180, 240 and 300 watt. Is one of those good or would stronger be better? I'm going to have the lights on a 18-6 cycle for the vegetation period and a 12-12 cycle during budding. I want to produce the most and best quality weed that I can, I just don't know if I get too strong of a light that it'll be bad for the plant or just a waste of electricity. Also, what would be best if I included a 3rd or even 4th plant? It's a rather large closet so I may end wanting to make the most of it.
