This INTER HUT portable walk-in greenhouse features a heavy-duty powder-coated steel frame, ensuring structural strength, long-term durability, and excellent weather resistance. The roof is constructed with a 4-millimeter double-layer polyethylene (PE) cover, which forms an efficient thermal insulation layer that maintains stable internal temperatures, blocks harmful ultraviolet radiation, and mitigates the adverse effects of extreme temperature fluctuations on plant growth. The translucent PE panels uniformly diffuse natural light, providing optimal illumination for plants while preventing overheating due to excessive solar exposure. The pop-up greenhouse is equipped with two zippered doors for convenient access and ease of daily operation, along with two ventilation windows that promote air circulation, helping to establish an ideal microclimate for healthy plant development.
