Why would you only want to get ten grams off each plant? They're in the vegetative stage of life. If you want ten grams off each plant, seriously, then turn them now
lol to answer my question yes u are using cfls if so how many u got? if u want at least a half oz id get 6 and a couple ysplitters and try to surround the plant with the light. the closer the better.. its all about placement with cfls
