If you take (2)150w HPS and (1) 600w HPS in a 6'x6' room, How many plants can you grow to full potential?
Is it just me GC, or does it take super-human willpower to not say something like "a gazillion" to posts like this? To answer your question though, it really depends. You could in theory get a 100 gallon pot and grow the single largest plant known to man, assuming you vegged her for an age and LSTd or SCROGGd the hell out of her. Or you could go with a SOG with 36 clones throw them straight into 12/12 and maybe produce a couple of pounds in a couple of months. Most people here do something in between. Remember you need space to get in and muck with each and ever plant, so do not forget to leave yourself some room to move around as it is foolish to stress the plants by walking through them. GL!
