RIGA 4 Greenhouse - 135 sq.ft. Precision-Engineered, High-Performance Design for Modern Living

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.

I asked a million questions to Andrew. I really researched this product. They answered all my questions and installed the Riga XL. I couldn't be happier with both the service and product. It's very rare you get this quality experience. The help I got in setting up the foundation to the greenhouse setup was amazing. Our greenhouse is even better than we imagined. We even purchased additional heaters and composting bins!

I bought my first Riga III Greenhouse in January of 2014. This is a sturdy little greenhouse! Lots of great features for the price. I did lots of "shopping around" before I purchased a greenhouse and just kept coming back to the Riga. By the end of my first "growing season" I sadly realized I had not bought a big enough one. I was determined to have something larger for 2015 so I started shopping around again. I just kept coming back to wanting another Riga. I was sold on its features and how sturdy it was. I knew it would survive our extreme Nebraska weather - wind, hail, rain, wind, snow, ice, heat, wind, cold....and did I say wind? Yep, my Riga endured and stood up to all that weather its first year. So.....in February of 2015 I purchased another Riga III greenhouse. I bought one identical to my first one and butted the two together to make one greenhouse! I now have all the room I need! And my plan to put the two together worked out perfectly! We mounted the door on the second greenhouse so it swings IN instead of out. I can close off the second greenhouse if I don't have plants in it or don't want to heat it. I now have two automatic roof vents, a window on one end and the divided door on the other end - just like it was when they were single greenhouses. The greenhouses butted together with only about a half inch space between them. We cut silver flashing and screwed it on to the outside of the greenhouses thus "connecting" them and sealing out any air. We also added clear calk to help seal and adhere the flashing to the greenhouses. There is absolutely NO air that seeps into the greenhouses through this small space. My greenhouses are mounted on 4X4 treated timbers. I have dirt floors which I have covered in ground soybean mulch which helps keep heat in and also absorbs water. They are firmly mounted to the ground with those tie downs that screw in to the ground. This greenhouse is secure! Might not withstand a Nebraska tornado, but it has stood strong through some 40-50 MPH winds. I am SO happy with my Riga greenhouse! I would recommend a Riga to anyone who is looking to buy a greenhouse. They are sturdy. I have no problem with keeping my Riga heated in the winter and cool in the spring/summer. And, like I said before, we have some pretty extreme weather here in Nebraska. You will not believe how quickly stuff germinates in this greenhouse. The conditions are perfect. My only advice would be to MAKE SURE you buy a big enough one the FIRST TIME! And....when it comes to assembly...the video that comes with the greenhouse is your best friend. Watch it at least once before you even attempt assembly. We took a laptop to our assembly site and watched the video step by step as we put it together. This being said it really wasn't that hard to put together and ours went up fairly fast. I just can't say enough how much I love my Riga greenhouse!

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.

I am the horticulturist and garden manager for a large private estate located in Southern California. I grow organic vegetables for the estate and a nearby restaurant. Prior to acquiring the Riga III, I purchased my organic vegetable starts from a local grower. I was limited to the varieties that they chose to grow and had to deal with a lower level of quality than I wanted. After doing a LOT of online research, I decided that the Riga was the greenhouse that I wanted. I felt that the price was more than reasonable for all of the features offered. The ordering process and subsequent delivery was problem free. While the installation was somewhat challenging - with the aid of the video and the written instructions it was assembled by a team of three capable men in just over a day. Our greenhouse sits on a poured concrete pad that we installed with a drain and an irrigation quick coupler. This makes it easy to water and to keep the greenhouse clean inside. The Riga III is very roomy and I am able to have 32 flats of seedlings growing at the same time. The quality of my vegetable starts is amazing now! Seeds germinate in just a couple of days. The diffused light allows is perfect. I directly attribute the improved quality of the vegetables I am producing to the Riga III. I don't have to deal with snow here in Southern California- but as my greenhouse is sited on top of a hill in full sun- I do deal with high summer temperatures and occasional high winds up to 60 mph. The Riga is the only greenhouse I found that has a back wall window. The cross ventilation that I get by keeping the top of the dutch door open and the back window open really helps with keeping my summer temps low which helps to keep both my vegetables and ME comfortable as I like to work in the greenhouse in the afternoons. The Riga has withstood the winds like a champ! Of course, I didn't have to use my own money to pay for the greenhouse. My employer did that. But, I am so in love with this greenhouse that I am getting ready to buy one myself for my own backyard! I highly recommend this greenhouse to anyone who wants a beautiful, functional, strong, easy maintenance, high quality greenhouse in which to grow beautiful plants of any type!

We bought the Riga 10x17 and while it presented a number of difficulties to a single person putting it up (I did get around an hours worth of help when I absolutely needed it) I managed to get it all assembled and very pleased with it. We had power added and installed 15 sq in paving stones over a 2 - 3" bed of playground sand that helps to hold in the heat and it stays above freezing when the weather outside doesn't and warms nicely to the 60's during mid 30's outside. Never did really get the thing going, just some lettuce right now, but hopefully will have more time in the spring to really deck it out as we had planned!

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

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!

I show off my greenhouse frequently to visitors—and everyone is impressed. I also have a couple of high tunnels. The Riga greenhouse serves another purpose—I start every vegetable in the Riga. I can, for example, start tomatoes in February, so they are over two feet tall and very husky by the time they go outside in May (usually in one of the high tunnels). If you are growing seriously, you will want a Riga. They are super insulated, the solar opener works beautifully, and the houses are exceptionally well made and should last for years. My only quibble is that the written instructions seem to have been written by Google Translate into English. A friend who speaks German said that even the German was hard to figure out. I recommend watching the video that comes with the greenhouse at least twice before starting. That said, once it's together, you will enjoy it and depend upon it for many years.

We love our Riga and use it all year round. We are in Santa Ynez, CA. and load it up for the winter to protect all of our succulents and frost sensitive potted plants. In the summer, we put shade cloth over it and it becomes a playroom for our grandson and a alfresco dinning room at night.
