Mirrors have many hot spots it's best to avoid those. Remember when you were a kid and played with the magnifying glass in the cracker jacks box and you burned leaves and ants?

Same thing will happen to your plants if you use Foil or mirror.
Zandor Reviewed by Zandor on . Mirrors on the walls? Good idea or bad idea? Hello everyone... :o SETUP (planned setup, that is): Closet cabinet with a hydro NFT system. 36"x20" Can I hang mirrors on the walls of the cabinet? Is there a reason not to do so? Are there any improvements over Mylar? Over aluminum foil? Over white paint? Thanks for your help ! :) -turtle420 :cool: Rating: 5
