More about Riga Greenhouses:

The RIGA 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 polycarbonate, 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.

Designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sunrooms, pavilions, pool covers, home additions, and commercial building, with 28 years experience.

The RIGA is attractive and beautiful to look at – fits well in to an upscale garden setting
Buying a greenhouse is like buying a car, they vary in cost from cheap to very expensive, the RIGA is a class similar to a Volkswagen/Volvo – stronger, more durable and better insulated, and offers many more features than the better selling brands.

With a combination of strong materials and durable hardware, the Riga is by far the strongest greenhouse under $5,000.

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.

Polycarbonate .
The polycarbonate glazing on the Riga is German made and believed to be of superior quality then the much more common Polygal or GE glazing.

polycarbonate over main body

10 MM twin wall polycarbonate in front & back walls for extra strength


Riga Optional Accessories

i

Regular Shelf with Poly Sheet

suspended shelving without braces underneath – therefore allowing for more storage space ( i.e. for a cart, wheelbarrow or long tools)

Shelves use twin-wall polycarbonate as the insert (the flat part) material, allowing for much better and more even light distribution through the greenhouses. Most other types of shelving are dark structures which do not let light through – or very badly at best.

i Regular Shelf with Black Trays
