The Benefits of Installing a Greenhouse

The greenhouse is an essential equipment for gardening enthusiasts looking to extend their crops all year round. It protects your plants from weather hazards, Optimises their growth, and allows you to cultivate delicate varieties that would not withstand winter temperatures. With a greenhouse, you can also anticipate spring sowings and enjoy early harvests. Here is an overview of the various benefits you can enjoy using a greenhouse for your crops.

Shelter Against Weather Hazards

The main advantage of a greenhouse is that it offers a protected environment for your plantations. Excessive rain, frost, strong winds, or extreme heat: the whims of the weather will no longer be an obstacle to the growth of your crops. In winter, it maintains a milder temperature, allowing you to extend the growing season. Thanks to the greenhouse, your plants benefit from a stable and adapted microclimate. This control over the growing conditions of your fruits and vegetables ensures rapid growth while ensuring the best yield.

Extension of Growing Seasons

One of the greatest advantages of a greenhouse is extending the growing season. It allows you to start sowings earlier in the spring and continue harvests late into the autumn. This way, you can cultivate varieties that require more warmth and time to mature. You can sow tomatoes as early as February, harvest strawberries in winter, or even grow tropical plants.

Protection Against Pests

Insects, birds, and rodents can cause havoc in your vegetable garden. A greenhouse acts as a physical barrier against these undesirables. By controlling the environment, you also limit the use of pesticides and promote a healthier and more environmentally friendly culture.

Depending on your space, needs, and budget, several models are available. Choosing the right greenhouse involves considering the size, materials, ventilation, and thermal insulation.

Different Types of Greenhouses

There are several types of greenhouses, each with its own advantages depending on the available space and desired crops.

Tunnel Greenhouse

The tunnel greenhouse is ideal for amateur gardeners looking for an economical and spacious growing space. It consists of a galvanized steel frame covered with plastic film. Its main advantage lies in its ease of assembly and affordable price. However, it is more sensitive to bad weather and has lower thermal insulation compared to glass or polycarbonate greenhouses. It requires good anchoring to the ground. It is perfect for vegetable cultivation and offers ample storage capacity.

Glass Greenhouse

Aesthetic and durable, the glass greenhouse is often considered the high-end model. It maximizes sunlight exposure and has great resistance to weather conditions while offering excellent thermal insulation. The glass greenhouse thus creates an optimal environment for plant growth. However, its price is one of the highest. Furthermore, its installation requires a stable ground and a solid structure. By installing a glass greenhouse, you must keep in mind that this structure will also require a more significant physical investment: it requires regular maintenance to prevent dust and algae deposits on the walls.

Polycarbonate Greenhouse

The polycarbonate greenhouse offers excellent thermal insulation thanks to its double-wall structure that traps air. Polycarbonate panels generally include a protective layer to filter UV rays, thus protecting plants from burns. Lightweight and easy to assemble, the polycarbonate greenhouse represents a good compromise between strength and efficiency. Its robust structure withstands extreme weather conditions, a major advantage for year-round crops. These qualities make it a good alternative to glass and plastic greenhouses.

Mini Greenhouse for Kitchen Garden and Seedlings

Perfect for small gardens or balconies, the mini greenhouse is a compact solution for starting seedlings, protecting delicate plants in winter, or cultivating aromatic herbs. It can be made of rigid plastic or plastic film with a metal or wooden structure. The mini greenhouse comes in various models to meet the specific needs of gardeners. The vertical version, with its stacked shelves, Optimises vertical cultivation. The tunnel model, on the other hand, is particularly suitable for early sowings and protecting young plants.

Lean-To Greenhouse

The lean-to greenhouse turns an existing wall into an asset for your garden. Leaning against the facade of your house or garage, it benefits from the warmth of the wall it is attached to. This configuration is particularly interesting at night, as the wall continues to gradually release the accumulated heat. Moreover, in addition to serving as a greenhouse, the structure can also be an additional living space in your home.

Choosing the Right Greenhouse

Choosing your greenhouse is not something to be taken lightly. Several criteria need to be considered to ensure an installation tailored to your needs and environment.

• Define the purpose of the greenhouse: Before investing, it is essential to determine the main purpose of your greenhouse. Do you want a greenhouse to grow vegetables all year round, overwinter fragile plants, or start early sowings? Depending on your answer, you can choose a model adapted to your needs.
• Determine the location: The location of your greenhouse is essential to ensure good growth of your crops. Ideally, it should be oriented north-south to maximize sunlight exposure. Choose a well-drained soil sheltered from prevailing winds. An installation near a water source will facilitate watering your plants.
• Determine the right size: The size of your greenhouse will depend on the space available in your garden and the amount of crops you want to shelter. A greenhouse of 4 to 6 m² is sufficient for a small vegetable garden or seed preparation. For large crops, or if you intend to grow fruit trees, you will need a larger greenhouse: choose it according to the quantity of plants you plan to grow and their average size.
• Material and structure: The choice of material for your greenhouse impacts its durability and efficiency. An aluminum structure is lightweight and corrosion-resistant, while a wooden structure offers a natural aesthetic aspect but requires more maintenance. Regarding the covering, plastic is as light as it is economical, however, it is less durable than glass, which can be fragile and rather expensive. Polycarbonate is an excellent compromise between insulation and strength.
• Ventilation and insulation: Good ventilation prevents excessive humidity and reduces the risk of fungal diseases. Opt for a greenhouse with windows or side openings to ensure natural ventilation. Insulation is also a key factor, especially if you are gardening in winter. Adding a wintering veil or heating may be necessary in cold regions.

Installation and Maintenance of a Greenhouse

Proper Positioning and Temperature Regulation of Your Greenhouse

Controlling the climate in a greenhouse begins with strategic positioning. Choose a zone protected from prevailing winds, at a reasonable distance from trees to avoid excessive shade. It is recommended to place it in a sunny location, oriented north-south to maximize sunlight exposure: this orientation allows it to benefit from the early and late rays of the sun.

But beware of overheating: it is preferable that the temperature in your greenhouse does not exceed 35°C. A digital thermometer placed at plant height will help you monitor temperature variations precisely. To evacuate excess heat inside the greenhouse, simply open doors and windows: air circulation will contribute to temperature reduction. To prevent this problem in advance, use a shading cloth during peak summer heat.

Cleaning and Maintenance of Glass and Plastic Sheets

Regular cleaning and maintenance of the greenhouse panes ensure optimal luminosity for your crops and the longevity of the structure.

• For glass panes, you can use a soft sponge and soapy water to remove dust and algae deposits that accumulate over the seasons. And don't forget to clear the gutters if your greenhouse has them.
• For plastic sheets, use a mixture of water and black soap and a soft brush to gently scrub the surface. Absolutely avoid corrosive products like bleach or chlorine, which could damage the materials.

Regularly inspect the fixings, seals, and openings to ensure good waterproofing. Replace damaged plastic films and make sure the greenhouse is securely anchored in case of strong winds.

Add a wintering veil to protect the most fragile plants and consider installing a small heater if necessary. Avoid snow accumulation on the roof, which could weaken the structure.

Grow Your Plants All Year Round with the Greenhouse

Investing in a greenhouse is an excellent way to Optimise your crops and protect your plantations from weather hazards. Whether you opt for a tunnel, glass, or polycarbonate greenhouse, the choice will essentially depend on the available space and the crops you are considering. By properly maintaining your greenhouse and adapting your crops to the seasons, you can enjoy thriving gardening all year round!
