Building a greenhouse is usually a labour-intensive DIY project for anyone. Purchasing a kit greenhouse saves on time involved and can prevent accidents due to poor construction. The Rion Greenhouse kits are available in numerous sizes and shapes and can be assembled and erected in less than two days. Which one you choose will depend on your available space for a greenhouse and the climate conditions in your area. The greenhouse model used in this article is the Rion GH40. Instructions for other models will vary slightly. The unique nature of the Rion greenhouses allows for adding expansion units.

Things you need
- Rion GH40 kit
- Measuring tape
- Spirit level
- Exacto knife
- Triazicide commercial insect killer
- Concrete foundation or wood deck
Locate the space in your yard for your greenhouse. You will need about a 3-foot clearance on all sides to allow room for construction and for getting around the outside of the greenhouse. The dimensions of the greenhouse are 8 feet by 6 inches on all sides and 6 feet 10 inches high. Use wooden stakes to map out the area the foundation will be laid in. The area should allow full sunlight for the plants and be as protected from wind gusts as possible.
Spray the area with a heavy concentration of commercial-grade Triazicide insect killer. A typical concentration for yard spraying is 118ml for every 2 gallons of water. For construction of the greenhouse use a concentration of 227gr for every 2 gallons and spray the area liberally. Allow the spray to soak into the ground for a full day.
Choose the type of foundation you wish to use. You can use a poured concrete foundation, which is recommended for areas with high winds. You can use a wooden deck of at least the size of the greenhouse. Or you can excavate a trench to anchor the base of the greenhouse to the ground. Regardless of which foundation you choose, the actual construction of the greenhouse will remain the same.
Lay out the pieces of the base of the greenhouse onto the foundation. Each piece is labelled and is found on page nine of the instruction manual. Choose the door placement to be away from prevailing winds. Each piece will be able to slide into a connecting piece. Begin with the corners, labelled "01," and connect to the "B2" with the connectors labelled "2D." When you are done, the bottom frame will be complete. Lock the bottom frame together with pins.
Level the bottom frame using your spirit level to ensure the frame is even. Measure the distance from the corners and make sure the distance from the north to south corner is the same as the distance from the east to west corner. Secure the frame to the foundation using a masonry bit for a concrete foundation and screws for a wood foundation. For trench foundations secure the pieces together and set them firmly into the trench.
Assemble the roof by connecting the pediment panel halves together with the couplers provided in the kit. The angled connector labelled "8A" will connect the two "R8" pieces. The "6A" and "7A" connectors will be at the opposite ends of the "R8" pieces and will be reinforced by the "E5" bar, which will connect to the lower slot on the "6A" and "7A" connectors. Lock the door frame bar into place with two locking pins.
Attach the "E4R" and "R2" profiles together using the pieces labelled "PN5L" (left) and "PN5R" (right). Lock these pieces to the doorway pediment using the locking pins. This will serve as the doorway frame to your greenhouse. Repeat these steps for the back pediment of the greenhouse.
Assemble the roof arches. These should be assembled prior to attaching them to the structure and carried to it when complete. Insert the cable, which is labelled "CAB40," through the channel of the "5A" connectors. Secure the cable to each side of the "5A" using the AS70 screw in the pin holes. Repeat this process for each arch included in your kit.
Snap the "RA1" glazing elements to the "spine" of the roof. Place each glazing element on each joint of the greenhouse structure. These will secure the resin frame pieces to the outside of the greenhouse. The resin frames will act as the "glass" part of your greenhouse and provide better insulation than glass.
Insert the round pipes, called "profiles" in the manual, into the foundation base. Your model should include 15 of them.
Raise the roof with some help from a friend and set it upon the profiles. The roof should slide into the profiles easily. Secure it into place with the locking pins.
Install each of the resin panels by sliding them into the side channels of each column. Install each of the resin panels into the roof sections. Cut and install the GF Sealer by inserting it into the channels on each resin panel.
Assemble and hang the doors. Walk into the structure and locate and seal any leaks you may find with pieces of the SF soft foam insulation.
Tips and warnings
- Trim any sharp areas or columns using an Exacto knife.
- Keep a build-up of snow from accumulating on the roof in the wintertime.
