Riga 14 ft. 2 in. x 19 ft. 10 in. Extra Large Greenhouse Kit is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from A Nice Functional and Sturdy Greenhouse It is now a year + later and I am still very pleased with this structure. It is very functional much more energy efficient than my previous one and has even survived a hurricane. Definately not a single man job and probably would have been much easier with three persons but two ole guys were quite successful.

Rated 5 out of 5 by from Tropical Greenhouse Upstate NY has long hard winters, but this Christmas (2016) it hit 96 degrees in my greenhouse and the tropical plants are loving it. The shape seems to shed the snow really well and it has enough height for most plants. I used 1/2 inch pipe insulation over the aluminum arches to minimize the condensation, I keep the humidity high for the plants. A gas furnace keeps it warm (65 degrees F) and a 1 KW grow light helps with the dark snowy days. If we're not out there I leave a portable heater's pilot light on to keep the carbon dioxide levels from dropping too low, there is only about 1 air exchange per hour (it seals well) and the plants need a little more carbon dioxide of optimal growth. The optional aluminum foundation worked well, and the floor is decorative stones in a plastic grid material that makes the stones very stable to walk on. The kits directions were good but don't under estimate the other work like leveling the site and bringing in gas, water, and electric. Exaco was very good about taking care of some minor parts issues with this complex kit. It is now a tropical paradise with bananas, papayas, plumeria, coffee, tea, avocado, cinnamon, orange, lime, guava, figs, Hawaiian tree fern and lots of orchids. We're very happy with it and everyone says it looks good.

Rated 5 out of 5 by from Great product and best support I've ever seen. I looked for a large greenhouse for a year. My wife and I choose the Riga XL because of the size and style. Best of all, we are super happy with the quality of the greenhouse and the support we got from Andrew and his team. I'm 63 and my wife is a little younger. We were able to put it together by ourselves with the great advice we got from Andrew. It took time, and at times was a little frustrating, but it was well worth it. When we ran into problems, Andrew solved the problems quickly and without question about whose fault it was. If I were to buy another greenhouse, The Riga and Andrew would be my first and only choice.

Rated 5 out of 5 by from Outstanding Product The purchase of our Riga was one of the best buying decisions my wife and I have ever made. It is a top quality and value product. My wife wants to divorce me and marry the Riga.The service and support we received from the folks at Exaco was in a word "Outstanding". We purchased our Riga XL in 2011. To avoid potential issues be sure to follow assembly instructions carefully.
