Riga III Greenhouse – Exclusive Sale

The Riga III Greenhouse is designed to be used to grow fresh vegetables, herbs, and flowers in the middle of winter. Other greenhouses use less than 8 mm twin-wall polycarbonate panels and are considered to be season extenders, to be used when only a slight night frost might be expected during the spring or fall season.

The Riga III Greenhouse is 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. The Riga III Greenhouse is 9 ft. 8 in. wide and 7 ft. 9 in. high, has 8 mm and 10 mm panels, and can be placed on a 20 in. wall if desired. A door drop down kit is available.

With a combination of strong materials and durable hardware, the Riga Greenhouse is by far the strongest greenhouse under $5,000. The polycarbonate glazing on the Riga Greenhouse is German made and believed to be of superior quality than the much more common Polygal or GE glazing. And a major advantage of the Riga Greenhouse’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.

  • Attractive and beautiful to look at – fits well in to an upscale garden setting
  • All roof windows come standard with automatic (solar-powered) window openers
