    Red yellow and blue tarps as shade cloth?

    Any reason to think that this is a bad idea? This is the south side of the greenhouse. The north side of the roof, which has only half the square footage, has blue tarps, opaque tarps, and no tarps, so there's at least some white light getting in.

    Is reflecting light not a good idea with a mirror either outdoor sun or indoor led. I.e. Reflecting towards bottom. Also, which side of the aluminum foil is best to reflect with? Thanx.
