Hybrid greenhouse series merge practical design with an aesthetic, functional and sturdy structure. Plants benefit from the balanced exposure to sunlight provided by two types of virtually unbreakable Polycarbonate panels, twin-wall at the roof and clear at the walls. Hybrid greenhouses are easy to install and include a galvanized steel base, a hinged door as well as other features that enhance their usability. The greenhouses are capable of withstanding extreme weather conditions for many years of gardening use.
