Hoklartherm Riga Greenhouse
The Riga is an outstanding choice for gardeners who need a year round greenhouse with a larger footprint than the Riga ‘s’. As the mid-sized option in the Riga line it falls between the Riga ‘s’ and Riga XL in both width and height, and is available in several different lengths. It features 8mm twin-wall polycarbonate glazing panels on its side walls and slightly thicker 10mm panels on its ends, making it extremely insulative. Like all Riga models, its sloped side walls are reinforced with 13 gauge aluminum framing and will stand up to high winds, pounding hail, and heavy snows. (In fact, the curvature of the walls tends to make snow slide right off). These features make the Riga ‘s’ a fantastic choice for wintertime gardening in challenging climates.
Features
- No crossbars in the glazing panels (stable base construction)
- Specially designed high-strength aluminum profiles
- Minimal wind resistance
- Curved side walls promote light entry
- No debris on the roof due to its onion shape
- Large hanging shelves and plenty of accessories are possible
Included in the Riga Greenhouses Kit:
- Profiles, glazing, rubber seals, and hardware
- Roof vent(s) with automatic opener(s) – number depends on model:
- Riga 3: 1x
- Riga 4: 2x
- Riga 5: 4x
- 1x Dutch Door
- 1x rear wall window

What Makes Hoklartherm a Quality Brand?
- The polycarbonate glazing on the Riga greenhouse is German made and of superior quality

- The frame profiles are interlocked and won’t come loose over time due to wind pressures
- All Riga greenhouses offer enough insulation to grow plants year-round
