Hey guys im just wondering if any one knows where i can find mylar to put in my grow box to keep heat down and light in.
Just about any store with a camping section. Look for emergency blankets.(they're silver and folded real small.)
Mylar does not absorb or retain heat. It reflects the hell out of light, though. And skip the space blankets, if you hold them up to the light you can see through them, light passing through is obviously light not reflected. You want horticulture-grade mylar, comes on rolls either online or at a hydro shop.
