i brought some c3 sheet and put it on my front facing wall of my grow room, so if the police use hand held thermal imaging they wont see the heat on my front wall, im venting out into my loft/attic and worried about the heat build up as you get the occasional hellicopter go by. I can put the c3 sheeting in the loft but wont be able to put it everywhere as the space up there is too tight. Any suggestions would be great
Anytime you have a room within a room your pretty safe. The heat is spread over a wider area and is allowed to disipate.
i dont have a room in a room, i have spare room as a grow room venting out into the attic/loft, thanks 4 your reply though.
it says its only 90 thermal resistant but usless you have like 6 x 600watt hps i dont think you should have a problem, could do the celing just to be safe
thank 4 replys.
