The Palram Nature Hybrid series greenhouse brings hobby gardeners the best of both worlds; the precise balance of two advanced polycarbonates and a durable 6' foot wide frame designed perfectly for smaller spaces and your growing needs. A healthy head-start on your garden begins with light management through Palram's market leading twin-wall polycarbonate. Twin-wall polycarbonate is the leading choice for quality hobby greenhouse coverings because of its durability, light diffusing properties and heat retaining ability. The twin-wall roof on the Hybrid blocks 99.9percent of harmful solar UV radiation and creates a system of diffused light, which helps maximizes plant growth and eliminates the risk of plant burn and shade areas. Crystal clear polycarbonate side panels are equally as durable and provide over a 90percent transmission of light. Palram's version of these virtually unbreakable polymers are made only with virgin materials that won't be brittle or discolor over time. Featuring a rust-resistant, green powder-coated aluminum frame and heavy-duty galvanized steel base, the Hybrid series greenhouse is designed to stand for years to come. Other features include integrated rain gutters to channel water for sustainable irrigation, a magnetic door catch and a single roof vent to help moderate air flow and temperature to maximize growing conditions.
