In this youtube video, you can learn how to make a simple functional greenhouse using old windows and a few other items. The plan is easy and affordable.

Choose a suitable location for your greenhouse, removing any big plants or buildings that can block the sun’s rays and making sure the site is clear of any obstacles. A gravel layer under the foundation also offers additional safety.

Planning the Design

Once you have a wooden perimeter base built to match the dimensions of your greenhouse, you can start building on it. A concrete slab is a solid option but can be expensive and also requires more material to build.

Once you have the materials in place it is a good idea to read the instructions and familiarise yourself with how to make your DIY greenhouse.

Gathering Materials

A homemade greenhouse is a dream come true for many gardeners. It can be much cheaper to build one than to buy a commercial one and it allows you to tailor the structure to your specific needs.

The first step is to gather the materials you will need. This includes the frame, the covering, and the floor. The most common frame material is aluminum. It is cheap, durable, and easy to cut.

Building the Foundation

The beauty of having a homemade greenhouse is the fact that you can make it exactly how you want it. That includes implementing energy-efficient systems that are fueled by clean sources of power.

Start by clearing the designated area of your greenhouse site and removing any rocks or tree stumps. The ground should also be sloped to ensure water flows away from the structure and prevents it from getting wet.

Assembling the Frame

Now that you’ve got the base in place it’s time to start putting your greenhouse together. This will involve building a wooden frame.

Make sure that you have some friends around to help with this. These coverings are HEAVY!

Installing Panels

Once you have a solid plan in place, the real work begins. Begin by laying the greenhouse floor. This can be as simple as a gravel pad or, for more stability, a concrete slab.

Next, install the greenhouse panels. It’s best to follow the instructions that come with the panels. Be sure to drill holes that are slightly larger than the fasteners, as this allows for thermal expansion.

Creating the Door

A greenhouse is a great place to grow plants year-round. It also offers protection from harsh weather conditions like rain, snow, and sun.

Choose the ideal location for your greenhouse and clear the area. Remove any rocks or tree stumps if needed.

Frame the walls of the greenhouse. Use aluminum, as it is durable and easy to work with. Wood is a good option too, as it insulates well.

Setting Up the Internal Structure

A solid, well-leveled base is a key factor in ensuring your greenhouse thrives. Otherwise, doors may not close properly, harsh weather could damage the structure and it can shift over time putting unnecessary strain on the panels.

It should also be located near a pathway for easy access when you need to perform maintenance work. This includes cleaning and repairing any glass or plastic exteriors that build up dirt and even algae over time.

Installing Ventilation

Greenhouses need plenty of ventilation, especially in hot summer weather. A perforated plastic duct can work nicely to keep the greenhouse cool.

Circulation fans are also an option for a DIY greenhouse. These provide a gentle breeze that helps with air circulation while also evening out pockets of hot air that may form near the greenhouse walls. Some come with thermostat plugs that automate the fan on and off according to temperature.

Positioning the Greenhouse

It is important to choose the right site for your greenhouse. Pick an area that will receive at least 6 hours of sunlight every day. Also, make sure the long side of the structure faces south or south-east for maximum sun exposure.

Finally, make sure the greenhouse is not near areas where children play. They may throw balls that can break the glass.

Installing Light and Heat Source

A greenhouse offers a unique opportunity to grow greens all year round. However, it can get stiflingly hot during summer and bitterly cold in winter.

To keep the plants healthy, you need to install proper ventilation. This can be done using vents, rooftop fans or exhaust fans. Also, you need a heat source to keep the temperature up. A wood-burning stove is a good option.
