General description Designed to fit most four tier mini greenhouses, this reinforced cover is a perfect replacement for a damaged cover and an ideal upgrade for a standard PVC cover. The reinforced polyethylene cover consists of an internal grid sandwiched between two layers of durable polyethylene, making it far more hardwearing than PVC. This 3-ply construction helps to stabilize the frame and provides better insulation for plants and flowers. A roll-up double zipped door with ties allows for easy access when watering your plants and flowers.
