True, but I'm going to have to agree with PharmaCan that heat cannot cease to exist. Aren't those materials designed to just deflect heat? They are used on things that we don't want heat to get into, or someplace we don't want heat to get past. However it will just be dispersed to somewhere else. That would mean that all of the heat would still be in my grow space.

But wait, dad gum it. Now I'm confused. I think something like that may work in my case, at least in my sealed hood. If the glass deflected heat, it would be deflected back into the hood to be carried off through the cooling duct of the hood, assuming my fan is big enough to make any difference. In order for this to work, it assumes my fan could take on even more heat and get it out just as fast. I don't think so. Arrgh, new subject for now please.
Opie Yutts Reviewed by Opie Yutts on . Plexiglass heat shield? I looked but didn't find much info on this. Does anyone have experience with using a plexiglass heat shield between their light and the plants? If so... The section of my closet in question is about 3 feet by 3 by 9 tall. At the top is a large carbon scrubber, and air is pumped in from two places; one at about 2 feet from the floor and one at about 4 feet. This section of the closet is fairly tightly sealed. 1) How much space (gap) should I leave between the edge of the plex and the Rating: 5
