Collection: Riga Greenhouse Kits | S, Large & XL Series

Riga Greenhouse Kits from Hoklartherm

The Riga greenhouse line from Hoklartherm is German-engineered growing infrastructure,  built for serious gardeners who want four-season performance, not a seasonal shelter that needs replacing every few years.

Colorado Gardeners

Colorado gardeners choose the Riga for three reasons: the twin-wall polycarbonate panels handle Front Range hail and UV intensity better than any other kit in this price range, the aerodynamic curved roof sheds snow and redirects wind rather than catching it, and the 13-gauge anodized aluminum frame is backed by a 15-year warranty. This is a structure built to last decades.

Riga Greenhouse Kit Series

The Riga line comes in three series  S, Large, and XL — covering 54 to 280 square feet. Whether you're starting with a compact backyard greenhouse or investing in a professional-grade growing space, there's a Riga sized for your property and your ambitions.
