video Instant Greenhouse pallet wrap
This is not the prettiest greenhouse BUT it does work very well. I have tested standard pallet wrap for UV and it has surpassed 2 years without a problem. The wrap clings and if wrapped properly, it will not separate in winds exceeding 35 miles per hour. Maximum temperature difference with a 4x8 ft absorber and a single barrel of water plus 3 additional back mirrors is 30f. The goal for the winter time is to allow natural light to penetrate the south side and redirect sunlight missing the greenhouse from the north side. Mirror arrays can be set for different times of the day with or without tracking.
