Why Buy Riga Extra Large?

• The RIGA 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. While other so called “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 Extra Large – 16 mm polycarbonate - is the largest commercial quality hobby-kit type greenhouse now available in the country
• Designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sunrooms, pavillions, pool covers, home additions, and commercial building, with 28 years experience.
• For shelving options, see our other RIGA products.
• The insulation factor is an incredible: R-2.0
• With a combination of strong materials and durable hardware, the Riga is by far the strongest greenhouse of its size under $10,000.
• The Riga XL offers 4 large roof windows - each with an automatic opener.
• The Riga XL comes with 4 "L-shaped" anchor bars (which attach to the inside of the base profiles) to attach the greenhouse to a concrete or wood frame.
• The polycarbonate glazing on the Riga is German made and believed to be of superior quality then the much more common Polygal or GE glazing.
• 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.
• German engineering - guaranteed top quality!
