The Palram Nature Hybrid Series greenhouse is the ingenious enthusiast greenhouse offering the precise balance of 2 advanced polycarbonates panels along with a strong durable frame, while perfectly designed to fit smaller spaces so you can start growing earlier and continue growing later. Not all polycarbonates are the same. 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 won’t shatter the same as glass. The twin wall roof block up to 99.9% of harmful solar UV radiation and the crystal clear side panels offer over 90% transmission of light to reduce plant burn. A ton of features are included with the Nature Hybrid greenhouse. Integrated rain gutters disperse rain water that 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 lower temperatures on warm days. Spend more time growing than building. 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 piece of mind. Palram’s offers a complete line of accessories, designed to make your Nature Hybrid greenhouse more productive, save space and more durable against the elements.
