Solar Heating Gro-Tunnel by DeWitt
Create a warm, humid environment for your Spring, Fall and Winter gardens. 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-heating water tubes that run along each side. Each tube holds 10 gallons of water, when heated will release heat at night.
