A rigid, permanent greenhouse rather than a seasonal cover. The resin frame assembles with pin-and-lock connectors and no tools, and the panels slide into the frame rather than clipping onto it.

A note on the name
This was sold as a Rion EcoGrow 2 for years. Rion is now part of Palram Canopia and the same greenhouse ships under the Palram name — if you have been searching for "Rion HG7012" and finding nothing, this is it.
Why twin-wall rather than clear glazing
Twin-wall polycarbonate diffuses light instead of passing it straight through. Diffuse light reaches lower leaves a direct beam misses, and it removes the hot spots that scorch whatever is sitting under clear glazing on a bright day.
Anchoring is the real job
This needs securing to a concrete pad or a heavy timber foundation. A rigid greenhouse is a large, light, sealed box, and wind load is what takes these down — not panel failure. Budget the foundation before the greenhouse.
Where it sits against the alternatives
Rigid and permanent, where an Ohuhu walk-in is soft-sided and seasonal. It also gives you ground rather than shelving, so you furnish it yourself — a wire rack makes a good bench.
