i havent ever taken a full dry weight from this room, some strains yield 3-5 oz, others yield 2-4, and we run 2 strains that only give 2-3 per plant. and we can fit from 25-45 plants in the room at a time, we use fox farms happy frog soil, fox farms full line of nutes, including the solubles and the L. basilicus stuff. we also use RO water, superthrive, molasses and bat guano. everything is in 3 gal pots and thesse strains got a 7 week veg under the big lights with a 6 week pre veg in 24 oz solo cups under a 4 tube 2ft t5. its actually 1 1000w, 1 600w, and 1 400w.
