The RIGA XL is truly a greenhouse by the European definition of a greenhouse - designed to be used to grow fresh vegetables, herbs and flowers in the middle of winter. Other “greenhouses” using less than 8 mm twin-wall polycarbonate are considered to be Season Extenders, to be used when only a slight night frost might be expected during the spring or fall season. At best, they can only be used to house established plants during the winter season.
The RIGA XL Greenhouse is designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sunrooms, pavilions, pool covers, home additions, and commercial building, with 28 years experience
With a combination of strong materials and durable hardware, the RIGA XL Greenhouse is an exceptionally strong greenhouse
The RIGA XL Greenhouse offers more window and door ventilation than other units in its class
The 16-mm triple-wall polycarbonate glazing on the RIGA XL Greenhouse is German-made and believed to be of superior quality than the much more common Polygal or GE glazing
One major advantage of the RIGA XL's construction method is that the frame profiles are permanently attached to each other, and won't come loose over time due to wind pressures
