Royal Victorian Hybrid Greenhouse Kit 12 x 20 ft. with 4mm Tempered Glass Panels and 10mm Polycarbonate Roof

The Large Royal Victorian HYBRID Greenhouse is a premium English-style greenhouse. Designed with 4mm tempered glass walls and a 10mm UV/Heat Block Twin-Wall Polycarbonate roof, this hybrid structure offers superior insulation, helping to maintain warmth in cooler months while reducing heat buildup during hotter seasons. The "milky white" twin-wall polycarbonate panels provide 58% light transmission, effectively diffusing sunlight to protect plants from harsh exposure. To ensure long-term durability, these panels are taped off at the bottom and include extra covers at the top to prevent moisture infiltration.

With dimensions of 12'7" wide x 19'11" long x 9'2" high, and 6'7" side walls, this greenhouse offers generous growing space for plants of all sizes. Ventilation is a key feature of the design, including six roof windows - four with automatic openers and two with spindle controls - as well as a louvre window equipped with a clear Lexan cover for winter use. The double sliding doors provide easy access, while the integrated misting system helps maintain the ideal humidity levels for plant growth.

Built for durability, the 17-gauge aluminum frame ensures resilience against wind and moderate snowfall, though snow should be regularly brushed off in areas with heavy accumulation. Additional practical features include a large bottom frame/base, large gutters with downspouts for efficient water drainage, and the flexibility to install doors and windows in various positions to accommodate individual preferences.

This greenhouse is the perfect choice for gardeners who require enhanced insulation, superior light diffusion, and long-lasting durability, all while maintaining the timeless elegance of a classic greenhouse design.
