Product Description

The TMG-GH1230 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 360 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.

Loving the rubbery stretchiness of the plastic film. It seems thicker than the regular 6mil UV greenhouse film from the hardware store. We've been blasting it with North Atlantic gales for 3 months and it's still standing. We are about to order a second one after the torture test we just put the first one through. We did find it too short for our application, so added a small knee wall of wood (aka sawed off pallets). We have since order extra tubing to make it 2.5' taller (part number 4) at a very nominal cost. These will be put through the pallet kneewall to add extra support. It howls here! I'll make a youtube video of how we made the economical knee wall and increased the height. We will add a few snow load supports too and I'll put that in the video as well. The end wall wiggle wire channel instructions are not helpful, but its pretty obvious how to attached it. The rest of the instrcutions were very clear.
