Would plexiglass be heat resistant enough to handle being under a light and insulate the bottom section of my tent from heat if i have good ventilation for the light ? Beause i would like to use the last couple of inches of space i have that is robbed from heat.

If you mean put the plexi right up to the bulb, bad idea. How many W's is your bulb. If you had the exact right version of "plexi-glass", and in the adaquate thickness, you might get it to work. The wrong plastic is gonna cloud up quick and possibly melt. There are allot of types of "plexiglass". Get some tempered glass or skip the idea. If you have the plexiglass, you could give it a try and keep a close eye on it for the first couple hours, but I'd use glass.

I mean within about 4-5 inches of the light. Plus i just thought that some of the cool tube esk products would use a plexiglass material to insulate the heat but let the light penetrate.

Glass only! You can have a glassier cut window glass to the correct size. At best, plastic will warp, break down, and haze over. At worst, it melts into goo and possibly catch fire.

you are better off buying some glass. The plastic will discolor from the heat after some time unless you are using cfl bulbs. If plexi glass could be used then you would see it used by hood manufacturers.

I will look into glass it sounds like a good idea. I wasnt set on this or anything just was asking around. My setup is good enough for me right now just seeing if i could get any tweaks out of it. I am running a 150w hps in a smaller grow tent temps dont get to bad until your just under that 3-4 inch range. Im running a exhaust fan coming out of the top and it seems to be efficient at creating a vacuum for fresh air to get through at the bottom.

And Real Styles as my post above said i was under the impression that some lights may have use it.

You asked a good legit question. The only dumb question is one not asked. If not for my experience with HID heat, I would of had the same idea as plexi is cheap and easy to work with. I tried it on a commercial clothes dryer where the glass window was broken out. Worked good for about a month and then cracked all to hell from the stress of heating and cooling. I myself am a DIY'er.
