Where to buy
Advertised prices, checked daily. Shipping is extra unless the retailer states otherwise — on a greenhouse, freight can change which seller is actually cheapest. We do not yet track a retailer for this model.

Climate notes
Our analysis of the published figures — not a manufacturer claim.
- Exposed and windy sites
- No published wind rating, but Grandio documents its anchoring more thoroughly than anyone else here — two kits, concrete and wood, with exact fastener counts per size. For an exposed site that specificity is worth more than most brands' headline numbers.
What we don't know
Anything marked not published means the manufacturer does not state it. That is a fact about the product, not a gap on our side.
Figures are the manufacturer's own, taken from its documentation. We have not tested this greenhouse, and reporting a rating is not endorsing it. Wind, snow, permitting and foundation requirements vary by site — confirm anything that matters with the manufacturer and your local building authority before buying. Prices are what the retailer advertised when we last checked and exclude shipping unless stated.
