Transparent polycarbonate panels allow maximum light transmission while retaining heat for early seed sprouting or for protecting plants late in the season. Adjustable roof openings provide proper ventilation and easy access to your plants. They can be opened just a few inches to create a flat top surface or opened completely to allow full access to the inside. The lightweight aluminum frame and rust-resistant hardware help prevent corrosion from affecting all of the components of your cold frame greenhouse, making it last for seasons to come.
