Riga V Greenhouse – Exclusive Sale

The Riga 5 is 9' 8" W x 17' 6" L x 7' 7" H  and is designed to be used to grow fresh vegetables, herbs, and flowers year round. 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 V Greenhouse is 9 ft. 8 in. wide and 17 ft. 6 in. long, 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.

The Riga V Greenhouse is designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sun rooms, pavilions, 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 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 Package’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.
