Keep your plants warm and protected throughout the harsh winter months with this Fleece Greenhouse Cover from Christow. The cover is designed to keep plants warm to a minimum temperature of -8˚C and comes in two sizes to fit Christow 3 tier and 4 tier greenhouses. Extra-Thick Fleece  The cover has a thickness of 65gsm for ultimate warmth and insulation. Despite its thickness, the cover is breathable to give plants the ventilation they require for strong, healthy growth. Double Zip Door  The cover has a roll up door with zips on either side of it. Simply unzip each side of the door, gently roll it up, and secure it into place using the integrated ties to easily tend to your plants. Easy to Attach The cover is fitted with durable internal ties to securely attach to the frame of your greenhouse. This will help to keep it in place during windy weather and protect it from blowing away. For All-Year Use Spring  During the spring, you can use the fleece cover instead of your existing PVC or PE cover to keep your seedlings warm and give them a head start for the summer months ahead.  Summer  When the weather hots up, you can replace the cover with the PVC or PE cover supplied with your greenhouse. Should you wish to, you can reattach the fleece cover during colder spells. Autumn  During the late summer and autumn months, the cover can be used to ripen chillies, tomatoes, and other crops. This will keep them growing for longer to give you an even bigger harvest.  Winter When the weather turns cold and frosty, you can place your existing PVC or PE cover over the top of the fleece cover to protect it from the rain and provide plants with extra insulation. 4 Tier Fleece Cover  Keeps plants warm to a minimum of -8˚C Size: H158cm x W69cm x D49cm (approx.)
