Riga s Series
The Riga S-Series Greenhouses are designed 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 a night frost might be expected during the spring or fall season. The Riga greenhouses are designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, with 28 years experience. The Riga S-Series Greenhouse has 8 mm and 10 mm panels and can be placed on a 20″ stem 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 3s 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.
The Riga 3s includes a large roof window which has an automatic opener to help keep the interior well-ventilated and at a comfortable temperature. The lockable, Dutch door provides easy access and is designed for quick installation.
The commercial-grade 8mm twin-wall polycarbonate panels on the sides and 10mm twin-wall polycarbonate panels on the front and back provide tremendous insulative value. They are extremely durable and are virtually unbreakable and provide much more efficiency than typical greenhouse panels. Gutters are not needed as the Riga’s unique design naturally diverts water away from the foundation.
