Product Description

The TMG-GHD3040 Light Deprivation Two Layer Greenhouse Grow Tent is a sleek, professional, year-round growing structure perfect for any type of grower. Two layers of cover protect your sprouts, seedlings and flowers from the elements and harness the seasons completely while still allowing direct sunlight to diffuse through for warmth and optimal growing conditions. This greenhouse is built to create 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 1200 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.
