As a recommendation though, use panda film! The stuff is extremely durable, highly reflective, waterproof, etc. etc. It is black one side, white on the other (hence the clever name), and is great for keeping light in where you want it and light out where you don't.
Apreciated!
4osiris Reviewed by 4osiris on . Mylar Or Flat White Paint? I'm a novice at the moment and will be attempting my first grow(hydroponically). My question is, using the DWC method, which of the two(mylar/flat white paint)is the best way to go in regards to maximum yields? Many thanks. Rating: 5
