I think i'm going to always be close or more than a gram per watt these 1st couple runs wich i think is good. I know a lot of people like the big plant theory but i have always produced in 6 inch pots and i think i can average 2 grams a watt once i get this dialed in. I also grow lots of differnt strains usually so the more plants the merrier for me. Minimal veg time and lots of buds have always been my style. I do believe in big plants just not in my house. I took more of a mathmatical approach to my grow i know what can be produced in a 6" pot under floros and with quadrupale the lumens i should be able to produce double this if not more for me that works out to me over a gram a watt. with big plants u can't guess you weight as easy i know that plant i posted to be 10 or more grams wich is acceptable for the first run cuz if the room was filled with all 36 a 10 gram avrg would be 360g close to a gram a watt. Thanx though for the info and comments tomato tomaato
