Residential Greenhouses

Halls Magnum Greenhouses are built for a lifetime of enjoyment.  Halls has been manufacturing quality, affordable hobby greenhouse kits for over 30 years. Each aluminum framed kit is easy to assemble. Halls Magnum Greenhouses incorporates all the best features available in a quality greenhouse. Cast joints and additional struts at the eaves and ridge provide extra strength. The higher sidewalls increase headroom and provides space for hanging plants. The 4 roof vents allow for increased ventilation, and the double doors allow for easy access. The Magnums are  available in Highgrove Green powder coat finish or mill aluminum frames.

Features of Halls Magnum Greenhouses

Features include sliding doors, large roof vents, complete weather stripping and optional automatic vent openers. Each greenhouse model has a prefabricated galvanized steel base available as an option. The base provides the firm foundation each kit requires. You may place the base directly on level, firm soil. The anchor stakes included with each base should be inserted in ‘pockets’ of concrete to secure the greenhouse to the ground. All Hall’s greenhouses are guaranteed for 15 years against any defect to the aluminum frame resulting from faulty workmanship. Each double-walled panel is 6mm thick. The polycarbonate panels are  pre-cut to exact size. Panels come with an ultraviolet (UV) resistant coating, and are warranted for 10 years (5 years against hail damage). Shipping to Continental US is included in pricing. If the base is ordered separately there will be an additional freight charge.
