Top of the line German Hobby Greenhouse (9 ft. 8 in. W x 17 ft. 2 in. L x 6 ft. 11 in. H; 108 sq. ft.). Most efficient design for Year-Round use. Special sloped roof provides maximum head room, but prevents snow build-up; hail bounces off and the design allows heavy winds to blow over the unit. Made with German precision engineering from heavy duty aluminum profiles and 8 mm and 10 mm UV coated Twin-wall Polycarbonate Glazing. Offers the best insulation in its category, R-factor 3.0-3.2. Uses less energy than other hobby greenhouse to heat. The unique design of the greenhouse has the best ratio between framing and polycarbonate panels, which allows for maximum light transmittance and less moving shade.

Rated 5.0 out of 5.0 by I LOVE this greenhouse I bought this greenhouse in 2009 from Exaco and have had wonderful success with it. I am growing vegetables, herbs and flowers. It is SO well built and holds up in the big winds and snow that I get at 6,000 feet in the Southern California mountains. I also love the ventilation in the greenhouse as we can get 80-90 degree temperatures in the summer. During the summer I leave the top of the dutch door open along with the window on the opposite side of the greenhouse. This, together with the automatic windows on the top of the greenhouse, allows me to grow in the heat of summer. I also love the shelving on one side o the greenhouse with the panels that I can take out depending on how tall the plants under the shelf grow. I highly recommend this greenhouse. May 28, 2015
Rated 5.0 out of 5.0 by Great greenhouse for amateur enthusiast I bought this close to 3 years ago and love it. It was fun to put together and I have since added electricity so I can run fans, heat (only a little on coldest nights), and grow light. I use it to winter over plants as well as grow seedlings. I'm in it almost every day. June 10, 2015
Rated 5.0 out of 5.0 by Riga 4 is a real winner at 3500 feet in Canada We bought a Riga 4 in the late fall of 2014. By the time it arrived the ground was frozen and snow covered so my husband and some neighbors assembled it in our garage. When the snow left early this year we got a bunch of friends to help move it to a pad in the garden and by March 4th I had planted lots of cold loving plants directly in the ground. Between the ground-planted crops and indoor-started plants being hardened off, the greenhouse has been continuously busy and productive ever since. COMPLETELY WITHOUT SUPPLEMENTAL HEAT, by mid-April we began harvesting loads of spinach, lettuce, green onions, radishes and bok choy until we began replacing these early veggies with heat lovers like tomatoes, peppers and muskmelon.There were a few nights early on where we had a borderline frost but no damage on the cool climate plants and now (June 7th) the trick will be to prevent overheating. I have had home made greenhouses before but NOTHING has matched the Riga performance. I am already harvesting peppers. This is all happening on a north-east facing slope at 3500 feet elevation in the Canadian Rockies. Amazing! June 7, 2015
Rated 5.0 out of 5.0 by Structural Integrity We purchased a Riga 8 and are pleased with the quality and strength of the product. Assembly was well documented. Customer service was exceptional. Exaco is a first class operation. The Riga system is perfect for our windy location. April 16, 2015
Rated 5.0 out of 5.0 by Innovative and functional! We purchased our greenhouse nine years ago and have been extremely happy with it ever since. The instructional DVD was invaluable in the construction of the greenhouse. April 10, 2015
Rated 5.0 out of 5.0 by Just starting with our Riga Greenhouse..What a joy Our Greenhouse is on its way...Just spoke with Kim who was a wealth of information and interested in what we will be doing with our greenhouse here in Falmouth, MA. As part of a community non-profit, Falmouth Together We Can Inc., we started a group called Well-Grounded; it is a Service Learning group that is made up of three teachers, English, science and woodshop; one community partner, an artist, about 15 students ranging in age fro 12 to 18 and the numerous business partners we have made over the past year. We provide spring and fall clean-ups to the Senior Center in town, churches in the community, plant the annual flowers for Veterans Day, shovel snow for our seniors, design and maintain our school Memorial Garden, and study, grow and sell organic, GMO free seedlings...thus the greenhouse. Our community has been incredibley supportive. We have one native partner who donated the funds for this greenhouse and another anonymous donor who gave 10k dollars to support our students. So proud of the students, and the fun I have is beyond words! Thank you Kim for making this adventure even more incredible! Stay tuned for pictures of set-up and completion. Kathleen April 9, 2015
Rated 5.0 out of 5.0 by Riga 3 is wonderful! We live on the eastern side of the Sierras where the wind "blows the sun away." The winds come over the mountain and can be quite ferocious, on a regular basis, every year, and we have seen heavy, heavy snow. Our Riga has survived 100-mile-an-hour winds here and has gone through numerous windstorms without a problem until we had a 120-some mile an hour storm in January. Then the wind caught the door and broke the hinges. Now that I have the metal hinges for the door it should be fine. It has also nicely survived heavy snows here; the snow slides off the roof. When we were looking online to find a greenhouse that would survive our climate, we ran across your website showing your husband standing straddling the peak, and we knew we had found what we were looking for. I can't remember what year we bought it, somewhere around 2007, and it has gone through everything nature could throw at it so far. I have put up garden-style lattice-work on steel poles on the windward side to help shield it somewhat from the wind, which has helped somewhat too. Your product is truly a step above the rest. Other greenhouses in this area have not fared as well. I have even tried to steer people who were in the market to buy greenhouses to the Riga. Again, thank you for your excellent product.

Rated 5.0 out of 5.0 by Riga 4 thrives in harsh New England weather I've had this Riga 4 greenhouse for 5 years. On Cape Cod, we have very beautiful summers and falls but winters can be brutal. We are a little sand spit sticking out into the North Atlantic. For example, this past winter we had over 100" of snow and hurricane force winds for many days at a time. The Riga greenhouse never has failed in 5 winters like this. It is absolutely built to withstand hurricanes. We use the greenhouse for seedling starts in the spring (starting around March 1) and then season extension in the fall from about October through January. We grow lettuce, spinach and micro greens in the fall and early winter. To regulate the warmth, we fill 3 large black plastic livestock watering troughs with water. They fit under the shelves on the north side of the greenhouse. The sun heats them up during the day and they give off their heat at night. This past winter they never froze inspire of many days of sub zero weather and cloud filled days. I am very happy with my Riga 4. March 13, 2015
