Do you prefer organic vegetables, fresh cut flowers, and tomatoes in middle of the winter? How about color in your backyard — year round? It is all possible with a RIGA greenhouse. The best possible value in its class.

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 Greenhouse is 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. With a combination of strong materials and durable hardware, the Riga Greenhouse is by far the strongest greenhouse under $5,000. The Riga Greenhouse offers more window and door ventilation than another units it is class.
