The DeWitt Gro-Tunnel is designed to protect your plants from almost every environmental danger while providing a safe, bright, humid environment for the plant to grow in. The tunnel is solar heated during the day which warms the two water tubes. As night falls the water bags release their heat into the Gro-Tunnel keeping plants from freezing.

gro-tunnel1The entire kit is designed to extend your growing season and provide all low-tunnel growing benefits in a single package. The top white fabric is made from the DeWitt Fleece Growing Cover that allows air, light, and moisture through while keeping the frost from ever touching your plants. The base fabric is DeWitt Weed Barrier which prevents weeds and other plants from growing in your crops area. All of these fabrics are water permeable and allow air flow around the plant and its roots.

Suggested Planting Method:


  1. Prepare the soil. Lay the 36" x 120" weed barrier fabric on your row. Install plants or seeds down the center of the weed barrier. Lay solar water tubes on both sides leaving at least 8" of fabric on the outer sides.
  2. Install the tunnel by pushing the wire supports through the fabric being extra careful not to puncture the solar tube.
  3. Fill the solar water tubes with water. Twist the end like a bread wrapper. Install zip tie and tighten, then fold the twisted section and install an additional zip tie around the twisted tubes for extra security against leakage. Close the end of the tunnel and watch your plants grow.
