With 2 I'm pulling 415 watts at the wall. I might be wrong but two may do it.Getting me one or two to play with. After i alter them how many would adequately cover a 4x4x80 tent?I'm thinking 2 or would i need 4 for maximum yield..
On another thread I think we had a rough estimate of 770 ppfd for a 2'x3' closet with just the one light, from what I've read cannabis can grow optimally between 500 and 900 ppfd. So twos probably in that range for a 4x4.
Someone correct me if I'm wrong though!
