The Riga 4s is a middle-sized hobby greenhouse for the serious gardeners. Its heavy-duty construction and twin-wall Polycarbonate glazing allow a problem-free growing all year long. This is a real greenhouse, not only a “season expander”. With 8mm UV coated Polycarbonate glazing on the sides and 10mm in the front and back, the Riga uses a thicker material that insulates better than a glass window in your house.
The Riga is designed, engineered and manufactured by Hoklartherm in Germany, where they have to deal with the drastically changing weather.
The “onion” shape provides no surface to snow or wind. Snow loads will just slide off the sides and severe winds blow over the greenhouse. The frame profiles are thicker or have a larger diameter than other greenhouses, which makes the construction stronger.
The large window opens and closes automatically according to the temperature inside the greenhouse. Additionally, you can open the upper part of the Dutch barn style door to provide great airflow. The door is wide enough to push a wheelbarrow into your Riga 4s.

Made in Germany with 30 years of experience!
The Polycarbonate glazing on the Riga is German made and believed to be of superior quality than the much more common Polygal or GE glazing.
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. For a better anchoring in the floor, you can add the heavy-duty foundation frame.
