The RIGA is truly a greenhouse by the European definition of a greenhouse. Designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses with 28 years experience. The Riga backyard greenhouse has a beautiful "onion-shaped" design, as well as being one of the sturdiest hobby greenhouses on the market. One major advantage of the Riga'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. The "onion" has no eaves or shoulders giving it significantly less wind resistance. The Onion has been tested against winds up to 80 miles per hour and has never been blown away (when properly anchored to the ground). No eaves also means no significant snow build up! This is not only attractive but aids in shedding snow loads. The Riga XL Greenhouse comes standard with 16 mm Triple wall polycarbonate glazing. No other hobby greenhouse kit on the market comes standard with this kind of insulation. The heavy duty lockable Dutch door offers increased ventilation options while preventing the unwanted access of animals and pests. 10 year warranty on covering and 15 years on the frame!
