I only have enough money for either mylar or black white panda film. The mylar is 97 percent reflective or so and the panda film is 90 or so percent. 7 percent isn't that big of a deal. But is there any advantages or disadvantages to either?
This is dependant on how good your fan system is bro REMEMDER mylar is better but will also raise your temperture whare black and white will not raise the temperture. Radient heat cannot be removed and mylar increses the radient heat. I personally use super Mylar and standard Mylar its all dependant on how eficient your fans are bro. All the best there EDITED I use black and white with mylar mix and match bro till ya get it right
i went with the black and white panda plastic cuz I built my rooms out of it. Mylar would have been near impossible to do that with since it rips and tears. It took me two layers to accomplish a fully lightproof wall and I haven't had to do anything since I essembled the rooms a few years back. Both will work very well, it doesn't much matter as far as which is better.
