I have a 4' 6' by 3' foot closet cleaned out and I need to make something to hold 2 4' fixtures and 2 2' long homemade 6 bulb cfl reflector. I need some ideas on something that is sturdy enough for that kind of weight. I will be growing 3 masterkush plants also in this area. Is this enough room for 3 of that strain to grow properly?
You can buy racheting light hangers on ebay for less than 5$ per light. Unless you build something from random stuff you have laying around, you aren't going to do any better than that.
I would build a wood frame around the inside of the closet. That would provide lots of support for lighting, fans, and anything else you need in there.
