Hoklartherm Riga 3s Greenhouse 8 ft x 11 ft 

Riga 3s 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 poly-carbonate, 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 Greenhouse offers the minimum insulation needed to grow plant year-round – others using less insulation cost too much to heat.

As the Germans like to call it the "Onion" shaped, this structure withstands strong winds.  Riga is the best structure for cold weather especially during snows. Snow will slide right off . The frame is really strong which explains why our customers always brag about keeping these greenhouses for a long time!

One major advantage of the Riga'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 poly-carbonate glazing on the Riga Greenhouse is German made and believed to be of superior quality than the much more common Poly-gal or GE glazing.

The Riga Greenhouse is by far the strongest greenhouse under $3,500.

In addition, great airflow is provided as you open the Dutch barn style door. As the temperature of the greenhouse changes, the over-sized rear window will open and close automatically depending on the inside temperature.
