ur grow is more than fine for a cfl grow, thou if u were to use hps u would easily triple ur yeild and more,but i kno that the cost is a problem for a lot of people, they look realy healthy and buds look nice, ul neva get a big yeild with cfl but all the same they look gr8, keep it up, remember to flush them for the last 10days n they should taste gr8 for u.!!
