Solar Heating Gro-Tunnel

The DeWitt Solar Heating Gro-Tunnel is constructed of DeWitt Fleece Cover, which absorbs the heat of the sun while allowing air, water and light through to stimulate growth. The Gro-Tunnel has two solar-heated water tubes that run along each side. Each tube holds 10 gallons of water that when heated will release BTUs of heat at night. The floor of the Gro-Tunnel is made from DeWitt Weed-Barrier Fabric, which collects heat, prevents weed growth and conserves soil moisture, in turn promoting healthy plant growth, thus eliminating the need for herbicides. Each kit includes two solar-heated water tubes and eight DeWitt Zip Ties, DeWitt Fleece Cover with built-in hoops and DeWitt Weed-Barrier landscape fabric.
