Im doing a cabinet grow this time around, and that means I need to get a smaller light and worry about ventilation.

My cabinet has a shelf on top that I was thinking of hooking to chains (it has screws underneath but id rather be safe) so its adjustable. What I was thinking about doing, instead of buying or building a nice air cooled reflector for a 250/400w hps, is cutting a hole in the board for the light to shine through, put a peice of lexan glass over the hole (keep heat out) and then just run a lot of ventilation out the top of the cabinet to keep that upper area cool.

I think this could work well with what I have in mind, however, being a peice of cheap cabinet would, I fear it may catch on fire from the lights heat. is there something I could place on the wood to prevent this, or maybe I could just get a peice of lexan cut it the size of the top shelf and just hang that up and set the light on it?

any thoughts appreciated
