Its meant to be 2000 per sq ft, but get as many as you possibly can. Go for the highest wattage.
LIP Reviewed by LIP on . Best ratio of Lumens/sq. ft.? I was wondering what the best ratio of Lumens/sq. ft. for veg. & flower? I heard about 3,000 lumens per sq. ft. but I was wondering if i should keep it there all the way through, or if the plant would like an increase or decrease at some point in growth. this is for the strain "white buffallo" (white widdow x white rhino) I'm not sure if it's more predominatly indica or sativa.
