Foundation & Anchoring Solutions
Steel Base Kit (Optional Upgrade): Planning to install in a windy or extreme environment? Grandio recommends the proprietary Steel Base Kit for maximum stability. This powder-coated steel system resists rust and corrosion while adding significant strength and rigidity to your greenhouse. As a bonus, it creates an additional 3″ of headroom. Each Steel Base Kit includes your choice of specialized anchors for earth/soil, concrete slab, or wooden decking installations. Frame-to-Base Brackets available for enhanced security.
Flat Mount Anchor Kit (Included): Installing on a concrete slab or wooden deck in a protected, fenced environment? The included Flat Mount Anchor Kit provides reliable anchoring with your choice of fasteners for concrete or wood applications. Note: Ground installations require the Steel Base Kit upgrade for proper anchoring.

Is a building permit required? You may not need a permit for your Grandio, but it is always a good idea check before you get started. We recommend you check local ordinances and requirements before setting up your greenhouse.
Is it strong enough for windy or heavy snow locations? Definitely. Grandio’s are all designed to withstand the most hostile environments with a wind rating of 76 MPH and snow load rating of 25lbs./ft² of snow. We offer additional roof and eave supports to increase the strength and durability of the greenhouse frame for the Element Greenhouses. Just follow the included directions for securing your greenhouse and you’ll enjoy many years of growing with your Grandio.
I live in the hot southwest will Grandio Greenhouses work for me? For people who live in high temperature areas of the country like Arizona, Texas, California, Nevada, or New Mexico we recommend our aluminum shade net. The aluminum shade net reflects the sun on the hottest days to help your greenhouse keep it’s cool.
How do the automatic roof vent openers work? The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling. No electricity needed!
How large is the roof vent opening? The vent opening is 18-3/4″ width by 22-3/4” length.
What is the difference in polycarbonate thicknesses? Polycarbonate is available in several different thicknesses and normally comes in single, double, and triple walled sheets that can vary in thickness from 1mm to 10mm. A good rule to remember is that the thicker the panel the better insulation you’ll have for your greenhouse.
Can these greenhouse be mounted to a concrete pad? The Grandio comes standard with a base that is meant to anchor it in the soil with concrete footers or a duckbill anchor kit. However, it can be mounted to a concrete pad with additional tools and hardware. For more information please refer to our online manual or give us a call 1-866-448-8231 to discuss options.
