I really appreciate that info. I'll read up on PPFD.You will need a TRUE 30 Watts per square foot to product OK buds. So make sure what ever you choose draws at least 100 watts from the wall. If you see this in an add 600W or 500W or 100W or something in this manner read the fine print. Also some of the scammers will put up PPFD numbers that do not add up. Spider Farmer had their SF-1000 with like 860's of PPFD and now it is at like 480's. Do you homework otherwise you are just going to have to buy a new light.
