The TMG-GH2020 Leno Cover Tunnel Greenhouse Grow Tent is a sleek, professional growing structure perfect for any type of grower. A waterproof, UV coated, ripstop tarp 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.

Steel tubes are added on the front and end walls to keep the cover tied down so you can ensure it stays secured. Your plants will have plenty of room to grow and flourish under the approximately 400 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. An almost 4' wide walk-through door allows you to easily transport materials, tools and new additions to and from the greenhouse.

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.

Good enough
Size: 15x6.8, Color: Black
As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.

Great, but bring your own inserts.
Size: 24x7.9, Color: Black
These work great, easy to install. Happy with them. Only problem was the instructions say don’t use the include inserts on wallboard, which meant I had to go out and purchase my own. That’s OK, because I like to use inserts I trust.

Love the shelves, great quality and design. They are very sturdy and perfect for my need. I ordered wine glass holders from Amazon and attached them to the shelves. Impressed and amazed at the look.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.
