FAQ

You have questions, no problem, we have answers.

How easy is the Grandio to assemble? Very easy. We’ve designed and perfected the assembly process with you in mind. We provide the tools and a step-by-step assembly manual and video and if you have any problems you can call us at 1-844 873-5764.

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 1-844 873-5764 to discuss options.

Can’t wait for your Grandio? Here’s what to expect.

How many boxes will I receive?
Your new Grandio ships in 2 or more manageable-sized boxes (the exact number of boxes depends on the size of your greenhouse).

How is it shipped?
Grandio Greenhouses are generally shipped via UPS Ground.

Can I buy a Grandio if I live outside the USA?
Currently we can only ship orders to the USA.

How long will my order take to get to me?

  • West: 2-4 business days

  • Northwest: 1-3 business days

  • Southwest: 3-5 business days

  • Midwest: 4-6 business days

  • East: 5-7 business days

Easy to move around inside

I love how much headroom there is. It doesn’t feel cramped at all, even with multiple raised beds and racks. The sunlight penitrates very well!
