Riga IVs Greenhouse – Exclusive Sale

The Riga IVs is 7' 8" W x 14' L x 7' 1" H.  The Riga S-Series Greenhouses are designed 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 IVs 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. The Riga S-Series Greenhouse is 7 ft. 8 in. wide and 7 ft. 1 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 an available option if you do this.

With a combination of strong materials and durable hardware, the Riga IVs Greenhouse is by far the strongest greenhouses 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 S-Series Greenhouse Kit'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.
