About the manufacturer
Hoklartherm
Hoklartherm is a German manufacturer of premium greenhouses, known for precise engineering and insulated glazing that keeps plants growing through cold seasons. Its RIGA and LivingTen lines are built for serious gardeners who want a greenhouse that performs year-round and lasts for decades.
The Hoklartherm Riga XL is the big brother of our Riga greenhouses. Every model is 14 ft wide and glazed with 16mm triple-wall polycarbonate, the best-insulating glazing in the Riga range. It is made for serious year-round growers, market gardeners and anyone who wants a walk-in greenhouse that handles cold winters.
Which Riga XL size is right for you?
- Riga XL 5: 14 x 16 ft
- Riga XL 6: 14 x 19 ft, about 280 sq ft
- Riga XL 7: 14 x 23 ft
- Riga XL 8: 14 x 26 ft
- Riga XL 9: 14 x 30 ft
A good rule: plan the size for what you want to grow in three years, not today. The 14 ft width fits two deep growing beds and a wide center path.
Why choose a Riga XL?
Triple-wall glazing loses less heat than twin-wall or single glass, so a large Riga XL can cost about the same to heat as a much smaller single-glass greenhouse. The rounded shape sheds snow and resists wind, and the reinforced aluminum frame is built for cold climates. Compare it with the smaller sizes in our Riga collection.
