The Riga XL Professional Kits are truly greenhouses by the European definition of a greenhouse - designed to be used to grow fresh vegetables, herbs and flowers in the middle of winter. Greenhouses that use 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.

Top Reasons for Choosing Riga XL Professional Kits

• The Exaco Riga Professional XL Kits are 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 Exaco RIGA XL Greenhouse Kits are an exceptionally strong greenhouse.
• The RIGA XL Greenhouse Kits offers more window and door ventilation than other units in its class.
• The 16mm triple-wall polycarbonate glazing on the RIGA XL Greenhouse Kits 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.
• German engineering - guaranteed top quality!
