【Quality of Vinyl Material】Our greenhouse vinyl house is made of thick polyethylene (PE) with 166% more PV resistance than conventional products on the market, and is UV resistant. It is resistant to deterioration and the film will not tear even in typhoons, making it suitable for the climate of Japan, which is prone to natural disasters, and enabling stable cultivation. The sturdy metal frame does not warp during use, providing high stability and firmly protecting all plants. 【Quality of Pipe Material】We use a highly durable galvanized steel frame, which is more resistant to corrosion and rust than conventional powder-coated frame greenhouses, allowing the house to be kept stable for a long period of time, and there is no need to worry about plants and flowers being damaged by bad weather. 【About Assembly】It can be easily assembled without special tools.
