Product Description

The TMG-GH3040-V2 Commercial Tunnel Greenhouse is a sleek, professional, year-round growing structure perfect for any type of grower. An EVA clear poly 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.
