Exaco RIGA Large Polycarbonate Greenhouse 10'6'' x 9'8'

Best Greenhouse for Cold Climates

The RIGA Large Polycarbonate Greenhouse is more than a structure—it’s a sanctuary for gardeners who refuse to be limited by seasons. Whether you're chasing year-round harvests, protecting delicate seedlings, or simply carving out a retreat surrounded by greenery, the RIGA delivers strength, efficiency, and craftsmanship that stand the test of time.

A Legacy of Quality 

Every RIGA greenhouse is born in the Hoklartherm factory in Germany, where they've mastered the art and science of greenhouse building. It's the same country that brought you luxury cars, precision tools, and now—the greenhouse your garden has been waiting for.
Backed by a 15-year warranty on aluminum profiles and 10 years on polycarbonate glazing (prorated after 5), you’re not just buying a greenhouse—you’re investing in decades of garden success.

We offer three options in the Riga series:

Riga 3 - 10'6'' x 9'8'' x 7'7''    3 Panels

Riga 4 - 14' x 9'8'' x 7'7''        4 Panels

Riga 5 - 17'6'' x 7'8'' x 14'      5 Panels
