So, I've reached a point where I need to spread my 2 1k hps lights apart to add square footage to canopy. Originally, my bulbs were 3ish feet apart. Worked for me and the canopy size. Now my bulbs are 5 feet apart. Is that too far apart? I'm going off studs in the ceiling, but I can screw 2x4s into the studs and move lights anywhere I want, that's just something I don't want to do with a full grow going. Really, I'm just looking for thoughts on the 5 foot bulb spread.
