Can you please tell me what you mean by " good results".http://boards.cannabis.com/indoor-gr...ell-clubs.html From the looks of it you feel as if you have achived good enough results to sell your pot to medical clubs. Im really wondering what kind of results you are looking for? Did you just recently expand your Grow OP to 12 plants up from 4,5,6,x,x? If so, considering your success rate with X number you should already be aware that more plants = more light. A grower who has grown pot good enough for medical purposes id assume would already have some clue to lighting? Maybe im wrong.
