Product Description

The TMG-GH1220 Tunnel Greenhouse Grow Tent is a sleek, professional growing structure for hobbyists and commercial growers alike. An EVA plastic film cover protects your sprouts, seedlings and flowers from the elements while still allowing direct sunlight to diffuse through for warmth and optimal growing conditions. This greenhouse is built with a rust resistant and corrosion free galvanized steel frame, creating a strong, stable and long-lasting solution for healthy plant growth.

Included wiggle wires make securing the plastic film overtop of the frame and into the aluminum lock channels simple and easy to do. Your plants will have plenty of room to grow and flourish under the approximately 240 sq-ft of covered space. Solar energy will seep through from all angles and be stored in the soil and inside the structure for a beautiful, budding ecosystem.

TMG Industrial carries a wide variety of cold frame tunnel greenhouse grow tents designed for needs from a backyard hobby gardener to a sizeable commercial produce grower. With over 30 different sizes and styles available, TMG Industrial has become one of the leading cold frame greenhouse distributors within Canada and the USA.
