Hello, I am a first time grower, i have been reading some stuff and getting info so i can grow some medical MJ, I already have white whidow seeds, and right now I am about to buy the lights for flo, but I havent because in the book I read it says that lights depends on the sqft you want to light, so im gonna start with 18 plants and they fit under a 6.9sqft that a 600w HPS lamp can light, but I talked with a friend that its in the same buissnes and he told me to buy 2 air cooled 1000w HPS lamps for these 18 plants but I dont know why this should be better? Jorge cervantes says one thing(that only depends on the space) and my friend other thing (that more watts are better) , I just want the best for my plants I dont care if i spend some extra money but I dont want to waste it either, I just want the best bud I can grow so if somebody can help me out by telling me which lamps are the best for this # of plants and why, I dont know if there is a # of lumens per plant or some rule I can get for Calculating the # of watts I need for my room because in the future I wanna go for 50 or more plants... (the growing medium is soliess mix and its a regular grow (not SOG or SCROG)(dont know the name for regular))
