Yes, there are several differences between Mylar and the ordinary white or milky drop sheeting. First, real Mylar is much more expensive than the ordinary [usually Polyethylene} plastic drop sheeting. Second, Mylar is EXTREMELY tough and resistant to pulling apart and tearing, which for your use is really not necessary. For use as a grow room enclosure I don't feel the added cost of Mylar is justified.
