Nice thanks for the information!They sale the same stuff at Home Depot a little cheaper to wraparound air ducts. Two pieces of mylar With bubblewrap in the inside. I like it. I know license HVAC technicians use it and test it with there little infrared gun . I think you will pay a lot more if you buy the grow store stuff versus just a regular HVAC stuff your choice in your dollar.
Nah, I just thought it was cool lolIt doesn't get that hot n ur room does it?
