GrowSpan Gothic Premium & GrowSpan Round Premium Greenhouse Systems

Why struggle with do-it-yourself greenhouse plans when Growers Supply makes it easy with various complete greenhouse kits. All our GrowSpan Premium Greenhouse Kits come with easy to follow greenhouse plans to make assembly easy. GrowSpan Premium Greenhouse Kits are suitable for the backyard hobbyist or the professional grower. The twin-wall polycarbonate covering provides strength, durability and elegance. Clear sheets are flame retardant, will not discolor and have up to 78 percent light transmission. GrowSpan Premium Systems for 12', 14', 16' and 18' wide greenhouses include a greenhouse heater in your choice of propane or natural gas, heater control blower, exhaust fan with shutter, intake shutters, circulation fan and a waterproof thermostat. The frame and end frame are manufactured from USA-made, triple-galvanized structural steel tubing. Ends and top covering are constructed from our 8mm twin-wall polycarbonate sheets which are lightweight and virtually unbreakable. Panels include UV inhibitors to prevent degradation and built-in condensate control eliminates water droplet formation for a healthier plant environment. The greenhouse comes equipped with a heavy-duty aluminum entry door which has stainless steel hinges and a latch. An optional second door kit is sold separately. Heavy duty ground posts are included with the GrowSpan Premium Greenhouse Systems. We recommend using a baseboard; our recycled plastic lumber comes with a 50 year warranty and is ideal. Choose from Premium Gothic or Premium round greenhouse kits. We also offer financing and leasing options for our larger greenhouses and accessories.
