Will this Catch Fire?

[8182KSKUSH]

Just a quick ?
I know a guy, he has a hydrohut, he uses a can fan to suck it out, and uses the passive intake designed into the hut. Question is that when the fan is "sucking" and the hut is closed, it bows the material in kind of like a convex on all 4 walls. The front wall with the zip up doors is almost touching the hood of a 400 watt mh, and you can feel the warmth on the outside of the fabric. It hasn't caught on fire yet! The fabric stuff it's made out of doesn't seem flamable, but I couldn't help but wonder if it may be. Thanks in advance! By the way there are 2 400 watters in there, and it's dimensions are 4*4*8 if that helps in factoring at all!:jointsmile:

Get some coat hangers and make stents. Like an umberella.That will keep it away from the light. I've heard of this happening to more than 1 hut. You could also make the intake larger. That would take care of some of the negative pressure.If it's a 4 for the intake,then go to a 6.
