The Palram - Canopia Nature Hybrid Series Greenhouse offers the precise balance of two advanced polycarbonates panels and a durable frame and is designed to fit smaller spaces so you can start growing earlier and continue growing later. Additional Features Not all polycarbonates are the same. Our panels are made with only virgin materials that won’t become brittle or turn colors over time. Polycarbonate is one of the strongest polymers, making it virtually unbreakable and it won’t shatter the same as glass. 4mm twin-wall roof blocks up to 99.9% of harmful solar UV radiation. Crystal-clear side panels offer over 90% transmission of light to reduce plant burn. Collect Rainwater Integrated gutters disperse rainwater can be collected for a sustainable irrigation system. For added ventilation, a roof vent (x roof vents) and magnetic door catch keeps oxygen flowing and temperatures lower on warm days. The aluminum frame is durable, maintenance-free, and rust-resistant, keeping your focus on growing and not maintaining. Easy DIY This greenhouse is designed as a do-it-yourself project without the need for special tools. A smart panel slide-and-lock system connects the frame precisely and quickly into place and polycarbonate panels slide easily into profile channels. Your Nature Hybrid greenhouse will be ready to start growing in no time. A 5-year limited warranty and US-based customer support give you peace of mind. Palram offers a complete line of accessories, designed to make your Nature Hybrid greenhouse more productive and durable against the elements while saving space.
