Replacement greenhouse cover is designed to fit greenhouse frames measuring H125cm x W69cm x D49cm which is the most common size of 3-tier mini greenhouse frames. It’s a perfect replacement if your existing frame is badly worn or damaged.  Durable Reinforced Cover  The cover consists of a white internal grid sandwiched between two layers of polyethylene for superior strength. Its far thicker than a standard PVC cover to reinforce the frame and provide greater wind-resistance. Ties allow you to easily secure it to your greenhouse frame.  Promotes Healthy Growth  Because the cover has a white internal grid, rather than a green internal grid like most greenhouses, it allows plants to absorb the levels of blue and red light they require for healthy growth. It also keeps them warm and insulated from the cold at night.  Roll Up Zipper Door  The door has zippers on either side to easily open and close. Ties at the top allows you to secure the door when rolled up to easily water plants and flowers. You can also leave it open to regulate the temperature and encourage pollination.  Before Placing Your Order  Please check the dimensions of your greenhouse before you order a replacement cover to ensure it’s the correct size. We suggest measuring your greenhouse frame and not relying on the dimensions labelled on the packaging when you bought your greenhouse.  Measuring Your Greenhouse Frame  Make sure your greenhouse frame is set up on flat, level ground before you measure it. Ensure that the poles and connectors are securely fitted together. If any are bent or damaged, it could affect the accuracy of your measurements and make the replacement cover harder to fit.  Frame Does Not Come Included  Please not that this is a replacement cover only and the greenhouse frame does not come included. Although we don’t stock replacement greenhouse frames, we do sell a large range of greenhouses which are supplied with both a frame and a cover.
