But like all the others said. If you want to load that room and Max out it's results we are down to help!!!! Usually a pound per 1000w light is numbers easily achievable after a couple grows. Good growers are hitting 1.5 and sometimes 2lbs per 1000w light. I work at my local grow shop and we push everyone to at least get a pound per light.... So let's say each dinafem yielded 3oz on the dot. You need 44 plants to get 8 pounds, 2 per light(11 plants to each 1000w) and it's going to be crazy hectic..... And also what kind of hoods are you running? May I ask what your ultimate goal is for this grow? Sorry to come with so many questions and things to input.... But you are really shooting to have a really nice sized grow and I'd like to see it go through with out a hitch for you and I just want to make sure nothing over looked.... Do you have the pots have you put them in to see how it looks?
