Overview
The RIGA XL Greenhouses are designed with 16mm, triple-wall polycarbonate glazing and large roof windows that allow for maximum light transmission. The unique shape allows snow to slide off and wind to blow over, making it suitable for growing year-round. The combination of quality construction, design, and optional accessories, make this greenhouse an excellent investment for the serious gardener.
The semi-diffused panels permits sufficient light and warmth for propagating seeds and starter plants in early spring, while providing diffused light which is ideal for growing plants full-term inside the greenhouse. These are perfect for someone who likes to grow plants and vegetables from seed, or to grow plants and vegetables through the winter months.

Base frame: This optional accessory is highly recommended. It is 6” high and is typically placed directly on the ground. The base frame attaches to the bottom of the greenhouse and provides a stable foundation.
Shelving: The shelving system hangs from chains rather than traditional braces that support from the bottom providing superior strength and reliability.
- Top shelving: suspended shelving with polycarbonate inserts. 14” deep.
- Regular height shelving: suspended shelving without braces allows for larger equipment to be stored underneath. 25” deep with polycarbonate inserts or heavy-duty seed trays.
Door Frame Extensions: If you’re interested in giving greater height to your RIGA greenhouse, you can place it above ground level by mounting it onto a 20” knee wall. This kit extends the door frame, completing your greenhouse.
Additional Roof Windows and Automatic Openers: These are recommended in areas where temperatures reach over 95°F when still using the greenhouse. Shade cloths, which we do not carry specifically for the RIGA greenhouses, are also a good investment in areas where one might use the greenhouse in hot weather.
Wheelbarrow Access Plate: This heavy duty access plate allows you to easily move a garden cart or wheelbarrow in and out of your greenhouse, empty or full! Made from heavy duty aluminum - 19.5" W x 21" L (each side) x 1.75" H in the middle.
Solar LED Light: This solar powered LED light comes with a 3 watts (80 mA) solar panel with 9' wire, mounting hardware and an LED light and housing (6"x7"). It produces 250 Lumens for up to 4 hours - after an average sunny day. Color Bright: 6000º K.
Black Seed Trays: These trays fit easily in to the optional shelving. These trays are used to make starting seeds and transplanting easier.
Adjustable Metal Hooks: A set of 5 metal hooks that are great for hanging lights, fans, flower baskets and other heavy items.
Plastic Hangers: A set of 10 hangers that snap into the grooves in the aluminum frame and are used to attach twine or rope to support tall plants like tomatoes or beans.
Exhaust Fan: This exhaust fan should be placed on a high location in the back wall. Pre-wired with 9' plug-in power cord. Available in a 12" (RIGA 2-4), 16" (RIGA 5) and 20" (RIGA XL).
Intake Shutter: Usually positioned in a high location in the lowest panel of front wall. Prewired with 9' plug-in power cord. Available in a 16" (RIGA 2-4), 20" (RIGA 5) and 24" (RIGA XL).
Warranty & Important Information
Warranty: the polycarbonate walls are under warranty against manufacturer’s defects for 10 years and the aluminum frame is under warranty for 15 years. The warranty on the glazing is pro-rated after 5 years.
Zoning restrictions: in some areas of the US, it is necessary to have a permit to construct a permanent structure in your backyard. A common restriction is that anything over 100 square feet will require a permit that would be issued by your municipal government or your neighbourhood association.
Flooring: We recommended using gravel, stones, pine straw or some other kind of weed control mat that allows drainage for your greenhouse flooring. Concrete slabs are not recommended
Shipping: These greenhouses ship on a pallet via standard motor freight. The freight carrier will call in advance to schedule delivery. You may need two people present to unload freight from the delivering freight carrier vehicle. If you have a difficult street, or dead-end street, please contact us before ordering. Shipments are delivered curb-side.
