Rion Eco Grow Greenhouse includes all the great features of our larger models, but in a smaller convenient size. The Eco fits to narrower gardens and smaller growing areas but doesn't compromise space. The Eco Grow Rion Greenhouse is cleverly engineered and easy to assemble; the profiles snap together requiring no tools. Manufactured with 4mm Twin-walled polycarbonate panels, which offer superior strength, safety, light diffusion and more heat insulation than standard greenhouses. Special rubber seals between the panels and frame not only diffuse the light but also insulate the greenhouse perfectly. in addition Rions durable frame is constructed from 100% UV protected thick PVC resin and held together with push-n-fit resin connectors, so construction of the greenhouse is literally a snap and go. The barn style design provides plenty of headroom compared to conventional greenhouses.
