well the best i can get from cfl`s, have to admit tho i am impressed so far, have little over 500 true watts on them so should be ok, and as long as its strong with some flavor i`ll be happy...
i went for a one shot grow to supply me for a while i didn`t think about a second lot as space is an issue, its a veg and flower room, could work out tho have two popped there a couple days old, going to use them as mothers for summer crop and next indoor aswell, i think the summer crop will go later, so theres the indoor lot as backup..
