RIGA XL Greenhouse

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 year round. 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 best in class 16mm triple-wall polycarbonate panels provide maximum insulative value and safety. It is extremely durable and are virtually unbreakable and provide three times the efficiency in terms of heat conductivity of even 8mm twin-wall polycarbonate. Gutters are not needed as the Riga’s unique design naturally diverts water away from the foundation.

The peak height of ten feet allows room for tall plants and growing trees, and there is sufficient interior space for the most avid gardeners. The heavy duty frame is made of reinforced aluminum and the unique “onion” design allows the greenhouse to withstand inclement weather with ease. Nothing short of tornadoes or hurricanes have ever destroyed a Riga Greenhouse.

Riga XL 9

The commercial-grade Riga XL 9 is a beautiful addition to any garden. Its spacious 14 X 29 interior gives you space for anything and anywhere you decide to grow.

The Riga XL 9 includes six roof windows, all of which have automatic openers to help keep the interior well-ventilated and at a comfortable temperature. The lockable, Dutch doors on each end provide easy access and are designed for quick installation.

Despite its large size, the greenhouse can be assembled in as little as a weekend depending on how much help you have. The process can be sped up if the site of assembly is prepared ahead of time by leveling it and installing whatever type of flooring and foundation is preferred.
