Mylar expense depends on how big of a roll you get, like a 4 ft wide by 50ft at 2 mil which I recommend because it is thicker and more sturdy runs like 35-40$ at least around here. However for an outdoor shed I say you should try some panda film that way u can keep heat signature in and moisture out as well as getting reflectiveness however it is a bit more expensive. But depends on your grow room measurements.
Hope this helps.
