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 Grandio customer support at 1-866-448-8231.

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. Grandiose are all designed to withstand the most hostile environments. We've added roof and have supports to increase the strength and durability of the greenhouse frame. 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 airflow 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 I buy a Grandio if I live outside the USA?
Currently, we can only ship orders to the USA
