The RIGA IIIs is uniquely designed with polycarbonate panels, and more windows than other units to allow for maximum light transmission. The combination of quality construction and design, along with the optional accessories to fit all of your growing needs, make this greenhouse an excellent investment for the serious gardener.
The polycarbonate cover panels of RIGA greenhouses are "semi-diffused". This permits sufficient light and warmth for propagating seeds and starter plants in early spring, while providing diffused light which is ideal for growing plants full-term inside the greenhouse. This is a combination starter/grower greenhouse, ideal for all-season use.
This 81 square-foot greenhouse is perfect for someone who likes to grow most plants and vegetables from seed, or someone who wants to grow plants and vegetables through the winter months. It’s also great for an orchid lover or grower!
Being a robust unit, the RIGA greenhouse can take up to 6-10 hours to assemble with two people.
Construction: The RIGA greenhouse is designed, engineered and manufactured by the Hoklartherm company in Germany – an industry leader with 30 years of experience. The frame is constructed of smooth-finished anodized aluminum. The walls are UV-coated, 8 mm twin-wall polycarbonate glazing on the side and 10 mm twin-wall polycarbonate glazing in the front and back for extra structural support. The unit comes with heavy-duty rubber seals and silicon caulk to seal around the windows.
Snow-load Capacity: The roof of the RIGA is aggressively angled and has no ridge on which snow or other debris can collect. Since there is no “shoulder” and snow does not accumulate, it is actually impossible to measure the snow load, but the roof has more than enough integrity to support a 185 lb person in the center of the panels. As well, the inside shelves are strong enough to hold several flats of plants – hanging the shelves from chains makes them stronger than traditional braces.
Ventilation: To compensate for large daytime to nighttime temperature variations, the RIGA Greenhouse has larger and more windows, automatic window openers with each roof window, an oversized rear wall window and oversized Dutch barn front door. There is also the option to add more windows to suit the climate where you live and the plants you plan to grow.
Warranty: The polycarbonate walls are under warranty against manufacturer’s defects for 10 years and the aluminum frame is under warranty for 15 years. The warranty on the glazing is pro-rated after 5 years.
Base frame: This optional accessory is highly recommended. It is 6” high and is typically placed directly on the ground. The base frame attaches to the bottom of the greenhouse and provides a stable foundation.
Shelving: The shelving system hangs from chains rather than traditional braces that support from the bottom providing superior strength and reliability.
- Top shelving: suspended shelving with polycarbonate inserts. 14” deep.
- Regular height shelving: suspended shelving without braces allows for larger equipment to be stored underneath. 25” deep with polycarbonate inserts or heavy-duty seed trays.
Door Frame Extensions: If you’re interested in giving greater height to your RIGA greenhouse, you can place it above ground level by mounting it onto a 20” knee wall. This kit extends the door frame, completing your greenhouse.
Additional Roof Windows with Automatic Openers:These are recommended in areas where temperatures reach over 95°F when still using the greenhouse. Shade cloths, which we do not carry specifically for the RIGA greenhouses, are also a good investment in areas where one might use the greenhouse in hot weather.
Adjustable Metal Hooks: A set of 5 metal hooks that are great for hanging lights, fans, flower baskets and other heavy items.
Plastic Hangers: A set of 10 hangers that snap into the grooves in the aluminum frame and are used to attach twine or rope to support tall plants like tomatoes or beans.
Black Seed Trays: These trays fit easily in to the optional shelving. These trays are used to make starting seeds and transplanting easier.

A note on zoning restrictions: in some areas of the US, it is necessary to have a permit to construct a permanent structure in your backyard. A common restriction is that anything over 100 square feet will require a permit that would be issued by your municipal government or your neighborhood association.
