This Outsunny replacement greenhouse cover will allow you to keep your plant-growing going, if the old shell should ever come to damage. It\'s made from PE mesh cloth, which helps to protect your crops from light rain, light wind and direct sunlight. The bottom edge extends a full 20cm all ways, which gives room to add weights and keep the cover in place. It features 6 roll up windows to allow air to circulate inside, and it\'s finished with a large zipped door for easy access in and out.
