Hoklartherm Riga XL 7 Greenhouse 14x23

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 8mm 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 winter. The RIGA Extra Large – 16 mm triple-wall 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, pavilions, pool covers, home additions, and commercial building, with 28 years experience.

With a combination of strong materials and durable hardware, the Riga is by far the strongest greenhouse of its size under $12,000.

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.
