When growing with a 400w MH/HPS light .. whats the area its recommended for? 4x4 area ? 3x3 area ? and does that mean anything under that 3x3 or 4x4 area that the light covers will grow to the max potential (if given the best conditions) ?
Not a stupid question IMO, I bet you get a million different answers. The math is out there. I think in the scrog thread it lays it out pretty well. I grow with a 400w HPS in a 20"x36" SCROG 16" from my light That footprint is determined by the size of my tent.
