1. Product Description: This passive solar greenhouse features a solid brick rear wall with excellent thermal storage and heat insulation performance, which can fully absorb solar heat during daytime and release warmth at night to maintain stable internal temperature in cold seasons. The front arch frame is constructed with hot-dip galvanized steel profiles, covered with high-transmittance anti-aging plastic film to maximize sunlight intake for crop photosynthesis. External sunshade racks are pre-installed on the top to adjust light intensity and cool down the greenhouse in hot summer.
