Greenhouses are a fantastic addition to any homeowner's backyard, especially if you're a plant lover passionate about making your space environmentally sustainable.
These structures offer numerous benefits, providing an ideal environment for plants to thrive and extending the growing season for various crops. They also promote sustainable living and can even help you cut expenses.
In this step-by-step guide, learn about and explore the process of building a small greenhouse, from planning and designing to selecting suitable plants for cultivation. Whether you're an experienced gardener or still watering your first plant, these measures will help you create a haven for your plants in your backyard.
Benefits of Building a Small Greenhouse
The advantages of constructing a greenhouse extend far beyond conventional gardening methods.
Extends the growing season
One of the significant benefits is the extension of the growing season. A greenhouse creates a controlled environment where you can plant without waiting for the seasons to be right. Early seeds in the spring will continue growing well into the fall, even in regions with colder climates.
A greenhouse provides a sheltered space to protect plants from extreme weather conditions, including frost, hail, strong winds, and excessive rainfall. These protective features ensure your plants thrive and remain healthy, resulting in more abundant and successful harvests.
Protects plants from pests and diseases better
Another advantage of a greenhouse is the ability to control pests and diseases effectively. Common garden pests such as insects and rodents cannot access your plants within the enclosed environment.
This protection reduces the need for chemical pesticides and promotes natural pest control methods. The controlled environment of a greenhouse also helps maintain optimal growing conditions, such as proper ventilation and air circulation, which further discourages the growth of pests and diseases.
Allows for great customization
The customizable environment within a greenhouse is another significant benefit. You can tweak and adjust the environment to make it ideal for plants to grow. It gives you control over the temperature, humidity, and even the amount of light that plants receive.
This control opens possibilities for cultivating plants that may not thrive in your local climate. You can grow delicate tropical plants in colder regions or experiment with exotic species that require specific conditions.
Makes year-round gardening possible
Even during the off-season, when the weather limits outdoor gardening, you can continue nurturing plants and engaging in your gardening passion within the protected environment of a greenhouse.
You can start seeds earlier, propagate plants, and even grow fresh produce during winter, providing a continuous supply of homegrown fruits, vegetables, and herbs.
10 Steps to Building Your Small Greenhouse
1. Create a plan and a design for your greenhouse
The first step is to plan and design your greenhouse carefully. Consider the following factors:
Available space and sunlight: Assessing your backyard to determine the best location for your greenhouse. Look for an area that receives ample sunlight throughout the day, as sunlight is crucial for plant growth.
Greenhouse size and style: Decide on the size of your greenhouse based on the available space and your gardening needs. Consider whether you prefer a freestanding greenhouse or a lean-to style that you can attach to an existing structure. The size and style will determine the layout and materials needed for construction.
Materials and design: research different greenhouse materials, such as polycarbonate panels or glass, to find the best fit for your needs. Each material has its advantages and considerations.
Additionally, sketching a greenhouse design will help you
visualize the layout and ensure it meets your requirements and budget.
It also helps to determine the purpose of your greenhouse. Are you growing vegetables, herbs, flowers, or exotic plants? Go for a diverse range of plants to maximize the utilization of your greenhouse space.
2. Prepare the site
Preparing the site is essential for creating a stable and functional greenhouse.
Remove any rocks, weeds, shrubs, or other obstacles from the selected area. Clearing the space ensures a clean and open place for construction. Use a shovel or rake to level the ground where you will place the greenhouse. Leveling is important for proper drainage and for creating a stable foundation.
Depending on your preferences and the local climate, you may install a concrete slab or raised beds as a foundation for your greenhouse. Research the pros and cons of each option and select the most suitable one for your needs.
3. Gather materials and tools
Before you begin construction, gather all the necessary materials and tools. Here are some essential tools you'll need:
Measuring tape: for precise measurements of materials and dimensions.
Screwdriver and drill: for assembling the frame and attaching components.
Level: ensures you align your greenhouse properly.
Hammer: for driving nails and securing parts.
Saw: to cut materials to the desired size.
Safety goggles, gloves, and a mask: prioritize safety by protecting yourself during construction.
4. Build the frame
Now it's time to construct the frame of your greenhouse. You have two options: prefabricated kits or DIY construction.
Prefabricated kits offer convenience and simplicity. Follow the manufacturer's instructions to assemble the frame securely. If you prefer customization, DIY construction is a great choice. Follow your chosen design or consult greenhouse plans from reliable sources to build the structure accurately.
5. Install the glazing
After completing the frame, it's time to install the glazing material. There are two common options: polycarbonate panels and glass.
Polycarbonate panels are durable, lightweight, and provide excellent insulation properties. They resist impact and UV radiation and offer diffused light for optimal plant growth. Glass, on the other hand, provides exceptional visibility and aesthetic appeal. It allows maximum light transmission, creating a bright and beautiful environment.
However, glass is heavier and may require additional structural support. Ensure a tight seal when attaching the glazing to the frame to prevent air leaks and ensure insulation.
6. Ventilation and temperature control
Proper ventilation is crucial for maintaining optimal growing conditions in your greenhouse. Install vents or windows that you can open and close to regulate temperature, humidity, and air circulation. You can also use automated ventilation systems or fans for consistent airflow.
Shading or blinds are other options to prevent overheating during the hot summer months. These coverings help protect delicate plants from excessive heat.
Remember to place thermometers and hygrometers inside the greenhouse to monitor temperature and humidity levels accurately. This information will help you adjust ventilation and temperature control measures as needed.
7. Design shelving and benches
Designing appropriate shelving and benches within your greenhouse will maximize space utilization and allow for efficient plant organization.
It's best to choose materials that are moisture-resistant and easy to clean. Common options include rust-resistant metal, pressure-treated wood, or plastic. Install the shelves and benches at suitable heights to accommodate varying-sized plants. This flexibility will allow you to optimize space and create an organized greenhouse environment.
Ensure easy access to all shelves and benches for maintenance and plant care. Leave adequate space for movement within the greenhouse.
8. Select the right irrigation method
Choosing the right irrigation method is crucial for providing your plants with adequate water while conserving resources. Drip irrigation allows plant roots to receive water directly from the source, minimizing waste and preventing foliage wetting. It offers precise control over water delivery and is ideal for conserving water.
Misting systems emit a fine water spray, creating a humid environment for plants that require high humidity. Many commonly use them for delicate plants or seedlings. However, depending on your plant's needs, you may opt for a combination of irrigation methods. For instance, you can use drip irrigation for established plants and misting systems for delicate seedlings.
9. Implement integrated pest management techniques
Maintaining a healthy and pest-free environment is vital for successful greenhouse gardening. Regularly inspect plants for pests, such as aphids, mites, or whiteflies. Early detection allows for prompt intervention.
To combat pests without harming beneficial insects or the environment, utilize organic pest control methods, such as insecticidal soaps or neem oil. You can also consider introducing beneficial insects like ladybugs or lacewings that prey on common pests. They help control pest populations naturally.
Practice proper sanitation by removing fallen leaves, debris, or infested plants promptly. These methods reduce the chances of pests spreading and establishing colonies.
10. Select suitable plants for greenhouse cultivation
Finally, choose plants that thrive in greenhouse environments. Different plants have varying light requirements. Group plants with similar light needs together to ensure optimal growth conditions.
Think about how temperature will affect the greenhouse's occupants. Select plants that thrive in the temperature range your greenhouse can provide. Consider the climate requirements of each plant to ensure their successful growth.
