Manual Riga Greenhouse Instruction Manual

The German engineered Riga Greenhouses have beautiful and practical designs combined with quality, long-lasting parts and pieces.

Easy to Assemble

The Riga features a sturdy rustproof, extruded aluminum frame. The unique "channel" design of the aluminum components allows for simple "slide and fit" assembly, thus saving time and money. Easy to understand step by step assembly instructions are included with every structure.


With the thickest twin wall polycarbonate offered on a backyard greenhouse, the Riga hobby greenhouse carries the highest R factor of any hobby greenhouse on the market. This makes the Riga less expensive to heat.


Most hobby greenhouses manufactured today offer 4mm or 6mm polycarbonate covering. The Riga hobby greenhouse carries the highest R factor of any hobby greenhouse on the market. It is covered with sturdy 8mm twin wall polycarbonate on the roof and side walls and the end walls are covered with heavy duty 10mm twin wall polycarbonate. This kind of covering provides better insulation making your Riga greenhouse easier to keep cool in the summer and warm during the winter months. The "onion" shape helps shed heavy snow loads.

Doors and Vents

The extra wide 30" heavy duty dutch door with keyed lock is wide enough to easily pass a wheel barrow through. The extra wide 40" x 24" automated roof window(s) and oversized 30" x 42" gable end window maximize the benefits of natural ventilation.

Most Fun Project Ever

Awesome Greenhouse. German engineering is evident in this product. The frame is strong and stout. And the Lexan pieces are very well made. Everything fit as it should. I'm so glad that I chose the Rega 9.8'x14' Greenhouse. I recommend this product for home or business use. Product support is excellent. At the start of my project, I noted two small brackets were missing. One email is all it took. I had the missing material in two days, no questions asked. Thank you Greenhouse Megastore, it's good to know you have my 6 on this project.

Love this Greenhouse

Bought this in 2015. Delivery went just as described. Assembly was challenging, but the customer service was excellent - even on weekends and after hours. We put geothermal tubing 6 feet under the greenhouse before assembling. During the first year we grew year round as an experiment. Had tomatoes all year, but supplemental heat during the -20 weather was too expensive. Geo air gives us an additional 15 degrees in winter, so we use February to November in eastern Idaho.Best feature is the automatic window opening at 70 ish degrees; keeps plants from frying both summer and winter.

Greenhouse great; instructions poor!

The greenhouse itself rates high; the outdated construction video and poorly translated (German to English) assembly instruction booklet rates low! Be prepared to email &/or call importer,Exaco Trading Co., frequently.

Legacy Review

It took four weeks for all of the parts to arrive! Thus I am still putting finishing touches on the greenhouse. Took two weeks to get 1st load of five expected boxes. Polycarbonate arived in 2nd week & had to be replaced due to shipping damage; this took an additional several weeks. Old video does not always jive w/ hard to read written assembly guide. An addendum sheet needs to be included at a minimum containing all of the latest changes: ie the 5 boxes are really only 4 boxes w/ optional base. Shipping company first delivered two boxes and then three boxes a week later; turns out that one of these was supposed to go to a customer in Pasadena, CA! Some assemblly operations take three people to get the job done.

Great Greenhouse

I am very happy with the Riga greenhouse. The included installation video was a life saver since the manual was a German translation. Order the optional base, even if you've made plans for a base already. Installation will take a minimum of 3 folks, just because you'll need that many hands. Assembly was not difficult at all. It took 10hrs. after the base was installed. I would buy this greenhouse again without hesitation.

Couldn't be happier

We LOVE our Riga! This is our first greenhouse experience and we wanted to jump in with both feet. My husband and I assembled it easily in less than a weekend. Customer service has been excellent. I recommend this store, and this greenhouse, regularly!

German Quality

The Riga is truly the BMW of greenhouse kits featuring quality German engineering, extra thick polycarbonate panels and a sturdy but easy to build frame. The extra large roof panels, side window and dutch door also offer the best natural ventilation of any hobby greenhouse kit on the market. You will not be disappointed.
