Choose a Location greenhouse

The first step is to pick a specific location in your backyard where you want to grow plants. Find the location on several factors such as greenhouse type, plants you want to grow, and exposure to sunlight.

No matter whether you select a cold frame or a standalone greenhouse plan, make sure that the spot you choose should always have as much sun exposure as possible and a good drainage system. Avoid building in an area covered by other structures or trees, as it may cast shadows.

Step 2: Create the Foundation

Create the Foundation greenhouse

The next step is to check your outdoor space for the foundation. If the space is uneven or has bushes or stones, clear everything. Also, for cold-climate gardening, the greenhouse base should always be lower than the frost line. This will help your plants warm in cold weather conditions.

A strong foundation will provide good support and strength to the greenhouse and stabilize it. Make sure to create a well-draining floor while building your foundation.

Gather small rocks or pebbles to add them as barriers or lines. Doing this will prevent the grass and weed from growing near your greenhouse. Also, due to this boundary line, your greenhouse area will not get muddy while you water your plants.

Step 3: Build the Frame

Build the Frame greenhouse

After finishing the foundation, it’s finally time to start building the greenhouse structure. So, gather your materials and prepare the basic structure with the help of a frame.

Greenhouse frames are available in various materials, including wood, plastic, and metal. You can build the frame separately or use the one that comes with a greenhouse kit. Use proper hardware and tools to build the frame carefully.

Follow the instructions written on the kit and use connectors, water sealants, and adhesives to join frame pieces. Also, you can create concrete posts to ensure your greenhouse is well anchored to the ground.

Step 4: Install Walls & Roof

After completing the frame, it’s time to install walls and roofs to your greenhouse. You can choose any material for the glazing, from plastic sheeting and glass to fiberglass and polycarbonate sheets.

If you’re creating a temporary structure, you can go with lightweight materials, but if you want something permanent, it is recommended to use high-quality and durable materials for glazing.

Slowly put the roof one by one with the support of the top beams. Attach them carefully to the greenhouse frame. Don’t forget to fill any gaps with a caulk or silicon sealant to insulate and secure your structure properly.

Step 5: Add Door & Ventilation

The final step of building a DIY greenhouse project is to add ventilation to your structure. Adding an appropriate ventilation system for your greenhouse is very important as it circulates the airflow and keeps the inside air fresh. Also, add a right-size door that is easy to open and close to access the greenhouse.

Without the proper airflow, there will be stagnant air in your greenhouse kit, leading to overheating, mold, or mildew. All these things may attract bugs and damage or even kill your plants. A well-aerated greenhouse will create the perfect environment to grow your plants. So, it’s crucial to install vents in your walls and roofs.
