using blackdog 400 phytomax (unfortunately, i found this forum too late) 8 weeks veg and 9 weeks flower, 7 gallon pots fox farms ocean forest, GH grow, bloom, bud enhancer, all variables seemed good, yield on three largest plants, one Green Love and two Girl Scout Cookies, drum roll please, 2.2 oz GSC, 2 oz GL, and picture in profile GSC 1.2 oz, of nice flowers.
I think that with better lighting those numbers will increase significantly, probably double. Next grow is going to be under COB vero29v7, 400 w framework from Timber Grow Lights.
