hello . well 2 out of 4 of my walls are made from carboard. I used it becuase it holds my fans perfectly and is adaptable. But im getting crazy heating issue.
For 1) i live down south but im still wondering is 2 walls of carboard really gonna do anything? Its the left wall with all the fans and the very top

welll yes its open. i wanted to close it (closet) but its just to hot. I could use a fan straight on but i think it will knock my babies over. Im waiting for maybe another week or two.

Cardboard seems like a good insulator, but its not really, it conducts heat pretty well over time. Bigger worry I think is the same as someone mentioned - fecking fire hazard. Hot lights + cardboard = not worth the fecking risk tbh mate. I found some stuff in B&Q the other day that was cheap as fook, it was that thermal insulating panels designed for use between walls. £5 for a big sheet of it. When I get settled and create a proper style growroom, I plan on lining my walls with that, with silver tape over the joins. Obviously thats no use if growing in a tent etc. But I'm monged at the moment, must be sativa dom as I can't seem to stfu, lol
