Hoklartherm Riga XL 6 Greenhouse 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 poly-carbonate, 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. The RIGA Greenhouse offers the minimum insulation needed to grow plant year-round – others using less insulation cost too much to heat. This is a well engineered and very sturdy greenhouse. Materials are top shelf.

The eye-catching onion-shaped structure will not fall below a load of snow. In fact, Riga greenhouses can face large hailstorms and winds as well. It assures that sunshine will continuously touch your plants because of the rounded construction.

16mm UV coated Triple-wall Polycarbonate on all four sides gives the highest insulative advantage that is available on the U.S. market right now. The glazing is remarkably long-lasting and practically indestructible while providing three times the performance in terms of heat conductivity compared to 8mm twin-wall Polycarbonate.

The Riga XL 6 Greenhouse comes with four roof windows. Each of them has an automatic, non-electric opener to maintain a well-ventilated interior. Riga XL greenhouses offer large roof windows and door ventilation than other greenhouses. It comes with two oversized barn doors for easy access. Open the top and let air flow through your greenhouse.

The high peak offers more headroom for tall gardeners. It is also useful for shelving space so you can double your growing space. The Riga XL Greenhouses shelves, that are part of an optional pro kit, are made of a white reflective material. The white color spreads the sunlight within your greenhouse to make it brighter. It also doesn’t emit heat like darker materials would do. These hanging shelves are space-saving and very sturdy. They can hold a high amount – for example, a 160-pound man.

It is made of reinforced aluminum for added durability and ensures that the frame is perfectly square. The lip of the base is actually meant to be placed in the ground, and the base kit is not needed when the greenhouse is already being anchored to a wood or concrete base.

      Assembly Tips For Hoklartherm Riga XL 6 Greenhouses

      While the process of assembling a greenhouse might seem daunting, these Riga

      Riga XL 6 greenhouse are designed to be assembled by people even with no prior building experience. Depending on your skill level, the size of the structure, and the number of options you order, putting together a kit can take two or three adults one full weekend.

      Many customers opt to hire a local handyman or contractor to simplify this process, and the affordable price of the kits makes it easy to do this. They can be readily found online at sites like AngiesList or HomeAdvisor. A version of the assembly manual is available as a PDF near the bottom of this page to give you a better idea of the process.

      Site Preparation - Customers often tell us that the trickiest part of the process is making sure that they have a good foundation upon which to build the structure. This foundation should extend around the perimeter of your greenhouse. It is ideal to have the foundation be as level and square as possible.

      Concrete pavers or pressure-treated wood with crushed stone is often used, though actually pouring concrete will give the most permanent installation. The greenhouse is designed to last for decades, and pressure-treated wood typically will fail well before that when used in outdoor applications, particularly in the ground.

      Exaco recommends that all the grass and weeds be removed from inside the greenhouse before assembly and that the area be covered with a weed control mat. Installing the greenhouse on a concrete slab may seem like an easier way to get started, but it's actually less than ideal, as the greenhouse floor should be free draining.

      Standing water on concrete can freeze easily in winter months, causing a slip hazard. And concrete slabs don't help regulate the temperature inside the greenhouse as well as other floors such as pea gravel, pine straw, riverbed stones, or just regular earth. Customers typically will create some sort of path down the middle of their greenhouse with flag stones, bricks, or even decking.

      The Hoklartherm Riga XL 6 greenhouse is made with serious growers in mind. Whether you are a keen gardener with plenty of space or a plant nursery, the Riga xl greenhouse is a wonderful greenhouse with a high specification that will last a lifetime.

                Riga XL 6 Greenhouse Additional Accessories

                Upgrade any RIGA XL Greenhouse with these optional accessories.

                  Foundation Frame

                  The Heavy-duty 6" tall extruded aluminum base kit is used when the Riga xl greenhouse is assembled directly onto the earth without the use of any concrete or pressure-treated wood foundation. It is made of reinforced aluminum for added durability and ensures that the frame is perfectly square. The lip of the base is actually meant to be placed in the ground, and the base kit is not needed when the greenhouse is already being anchored to a wood or concrete base. Greenhouse frame slides directly onto base. The shipping box is 240 inches long by 10 inches wide and deep and weighs 95 pounds.

                    Assembly Tips For Hoklartherm Riga XL 6 Greenhouses

                    While the process of assembling a greenhouse might seem daunting, these Riga

                    Riga XL 6 greenhouse are designed to be assembled by people even with no prior building experience. Depending on your skill level, the size of the structure, and the number of options you order, putting together a kit can take two or three adults one full weekend.

                    Many customers opt to hire a local handyman or contractor to simplify this process, and the affordable price of the kits makes it easy to do this. They can be readily found online at sites like AngiesList or HomeAdvisor. A version of the assembly manual is available as a PDF near the bottom of this page to give you a better idea of the process.

                    Site Preparation - Customers often tell us that the trickiest part of the process is making sure that they have a good foundation upon which to build the structure. This foundation should extend around the perimeter of your greenhouse. It is ideal to have the foundation be as level and square as possible.

                    Concrete pavers or pressure-treated wood with crushed stone is often used, though actually pouring concrete will give the most permanent installation. The greenhouse is designed to last for decades, and pressure-treated wood typically will fail well before that when used in outdoor applications, particularly in the ground.

                    Exaco recommends that all the grass and weeds be removed from inside the greenhouse before assembly and that the area be covered with a weed control mat. Installing the greenhouse on a concrete slab may seem like an easier way to get started, but it's actually less than ideal, as the greenhouse floor should be free draining.

                    Standing water on concrete can freeze easily in winter months, causing a slip hazard. And concrete slabs don't help regulate the temperature inside the greenhouse as well as other floors such as pea gravel, pine straw, riverbed stones, or just regular earth. Customers typically will create some sort of path down the middle of their greenhouse with flag stones, bricks, or even decking.

                    The Hoklartherm Riga XL 6 greenhouse is made with serious growers in mind. Whether you are a keen gardener with plenty of space or a plant nursery, the Riga xl greenhouse is a wonderful greenhouse with a high specification that will last a lifetime.

                    About Hoklartherm GmbH

                    Hoklartherm GmbH Corporate Overview (German)

                    Since 1982, Hoklartherm GmbH has been designing, engineering, manufacturing, and distributing premium greenhouses and outdoor structures throughout the world. The company began as a maker of arched greenhouses and the unique Riga design has remained popular ever since. 

                    From this first arched design has come a series of incremental changes to make the Rigas among the very strongest greenhouses available anywhere. The frames have been engineered for strength and to shed off snow and the commercial-grade polycarbonate panels add extra strength to the structure. Hoklartherm now makes beautiful and unique pavilions as well which have been widely installed throughout Europe in parks, commercial settings, and luxury private gardens.

                              Ask a Question
                              • Is it easier to build this greenhouse by using the optional base?

                                The optional foundation frame makes the anchoring of the greenhouse easier and without the use of concrete. To use the foundation frame you will need to dig a trench 5” deep the size of the perimeter of the greenhouse into which the foundation would be buried. If you do not want to use the foundation frame, the greenhouse will need to be anchored in some other way. The foundation frame won’t affect how the greenhouse is assembled.

                              • What are the complete accessory Kits for this Greenhouse?

                                Below are the suggested Accessories.

                                Foundation Frame
                                The base kit used when the Riga greenhouse is assembled directly onto the earth without the use of any concrete or pressure-treated wood foundation. It is made of reinforced aluminum for added durability and ensures that the frame is perfectly square.

                                Door Extension kit 
                                An extra panel can be placed about the door of the Riga so that it drops down by 20 inches. This allows for the greenhouse to be built upon a stem wall (knee wall) foundation. 

                                RIGA XL 6  Re-inforcement kit
                                New Addition to Hokalterm  Accessories which helps increase wind burst load to 135 MPH and Snow Load to 64 lbs. / sq.ft.

                                Roof Windows

                                Though this Riga greenhouse already includes a sufficient number of windows, extra roof windows are available to provide even more ventilation. Each window is 40 inches x 24 inches and includes an automatic opener. This opener does not require electricity as it has a special paraffin oil cylinder which expands and contracts based on the temperature. The temperature range on the automatic opener is adjustable.

                              Last year's tomato crop in my west Riga greenhouse

                              The 2017 tomato crop was the must successful I've ever had. Our first harvest was April 30, and a plentiful supply continued until January 4. From the two Rigas we harvested close to 700 pounds of tomatoes, some of which were consumed fresh and most of which were juiced, canned, dried, or otherwise preserved for winter use. The indeterminate plants in the west greenhouse were each more than 26 feet long when I removed them in January.

                              I tried a new approach for plant support in the west Riga. I've included a succession of pictures taken through the 2017 season showing the progress. I hope you find them interesting.

                              My Fav greenhouse

                              One of the best greenhouses you will ever buy. Quality built, great for growing or wintering plants due to triple wall polycarbonate and sheds ice and snow well. Dave at shopgrowspaces was very great at helping me through the whole process. What customer service should be. Thank you Dave!
