Our walk-in tunnel greenhouse offers an expanse you can use for all sorts of plants: vegetables, fruits, flowers, herbs, succulents, and tropical saplings. Take control of heat and humidity to extend your growing season. Offering an extra-large amount of space, grow big. Our tunnel greenhouse protects plants from wind, rain, and cold with a 140 GSM PE cover, a material that lets in 85% of nourishing sunlight without the worry of UV scorching. Featuring a tear-resistant reinforcement grid, our greenhouse is outdoor-ready. Please bury the 6 in. extended edges to ensure stability and a proper seal against rainwater. Our tunnel green houses feature a heavy-duty galvanized steel frame capable of withstanding water without wearing out, chipping, or peeling. Our green houses have a frame that stays strong from form and substance with 4-slant supporting rods. Please use the 4-guy ropes, and support stakes to mount it to soft ground. With the 6-roll-up windows on our outside greenhouse, you can vent off moisture slowly, carefully reaching the right levels. With the large, zippered door of our greenhouse, you can clear out the air quickly or enter and exit, sealing the space behind you to keep air trapped inside.
