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.

The RIGA is attractive and beautiful to look at – fits well in to an upscale garden setting
