The Grandio Ascent 8X16 Aluminum Greenhouse is a wonderful addition for gardeners off all experience levels. It features a classic A-frame style and everything you need to get started including the base kit.
The Grandio has been designed for durability as the frame is made of high quality extruded aluminum and a snow load kit is included to further strengthen the roof. The powder-coated green frame fits well in any setting, and the greenhouse comes with an industry-leading 10 year limited warranty on the panels and a limited lifetime warranty on the frame.
The panels are of the highest quality as well, as the Grandio includes 6mm twin-wall polycarbonate wall and roof panels that are both UV-stablilized and impact resistant. These provide significantly more insulation than the typical 4mm or single-wall panels found on other units.
The Grandio is designed to be assembled in only a weekend or less depending on how much help you have with just common household tools. The kit includes items that are optional on other greenhouses like the heavy duty steel base and and rain gutters on both sides, and the greenhouse can be easily expanded in 4 ft. increments to meet all your future growing needs.
