I know, this is a really dumb question - but I just can't figure it out XD I have a 400 watt super-sodium lamp and I'm growing in a 4.5x4x2' closet with the door open for ventilation. My friend says the bulb needs to be a foot away from all surrounding surfaces, or it'll burn them - so I can't attach it directly to the ceiling or the walls. I don't have a reflector, I was planning on just using some foil. How should I attach the bulb from the wall or ceiling?? How do most people do it?
I know it sounds stupid but I'd be grateful for any advice
