Greenhouses and outdoor aquaponics kits

An outdoor aquaponics kit is a compact, turnkey solution designed for those looking to easily get started with this sustainable growing method. Installed in a garden, on a terrace, or on a spacious balcony, it transforms a simple pond into a truly productive ecosystem, where fish and plants coexist. More fun than truly agricultural, it appeals to hobbyists and curious gardeners who want to discover aquaponics by producing some fresh vegetables while livening up their outdoor space.

The aquaponic greenhouse is an installation designed to go far beyond the simple discovery of aquaponics. Larger and more comprehensive than a kit, it is aimed at those who wish to move towards true food self-sufficiency. In a greenhouse, fish and plants thrive in a protected environment, sheltered from bad weather, frost, or excessive rain. This ensures much more regular and predictable production. Thanks to the heat accumulated during the day and retained by the structure, it is possible to extend growing cycles and even grow crops in winter in some regions.

An aquaponic greenhouse isn't just about growing salads or herbs : it opens the door to growing a variety of vegetables, even small fruits, while also allowing for the breeding of fish in sufficient quantities to truly contribute to a family's diet. This dimension makes it a more ambitious and demanding project, requiring space, careful planning, and a larger initial investment. But in return, it offers more complete food independence and an immersive experience in a complete ecosystem.

An aquaponics kit installed outdoors doesn't have the same purpose as a greenhouse. Its strength lies in its simplicity and accessibility. Easy to install and maintain, these small systems allow you to discover the principles of aquaponics without becoming overly complex. They transform a garden, a terrace, or even a large balcony into a vibrant and interactive space, where you can observe fish, grow a few vegetables, and learn about the functioning of an ecosystem.

These kits are particularly interesting for hobbyists looking for a compromise between aesthetics and production. Unlike a purely decorative pond, they add a nutritional dimension to the outdoor space. Even if the harvests remain modest, the pleasure of watching your own plants grow and raising a few fish makes it both an educational and fun experience. They also allow you to familiarize yourself with the basics of water management, biological balance, and the nitrogen cycle, which is an ideal first step before possibly considering a more ambitious project.

The benefits of an aquaponic greenhouse go far beyond the simple pleasure of growing. It offers a large production area, protected from the vagaries of the weather, and guarantees greater stability of the parameters essential to aquaponics. Thanks to this controlled environment, plants grow faster and fish thrive in safer conditions. This allows for significantly higher productivity than an outdoor kit.

Additionally, the greenhouse offers true continuity in cultivation. While an outdoor kit remains dependent on the seasons and can be slowed down in winter, the greenhouse ensures regular production for much of the year. It thus becomes a powerful tool for moving towards food self-sufficiency, reducing dependence on traditional distribution channels, and engaging in a more sustainable approach. By carefully choosing fish species and vegetable varieties, it is possible to diversify production and ensure a healthy, local diet for an entire family.

Investing in aquaponics requires adapting your budget to your ambitions. An outdoor aquaponics kit generally costs between €1,500 and €6,500 depending on the size of the pond, the materials used, and the options offered. Some simpler models can be rented, which reduces costs, and it is also possible to build your own system from spare parts.

Aquaponic greenhouses represent a more substantial investment, ranging from €4,000 for basic models to over €20,000 for larger structures. This higher cost is explained by the acquisition of more substantial equipment and its capacity to ensure diversified and continuous production. The budget therefore remains very variable !

One of the major advantages of outdoor aquaponics is the diversity of possible crops. In a kit, easy-to-grow, fast-growing plants like lettuce, herbs, or cherry tomatoes are often preferred. However, it's also possible to grow strawberries, which are particularly well-suited to this type of system.

In an aquaponic greenhouse, the possibilities expand : you can grow more demanding vegetables such as eggplants, melons, cucumbers or even large tomatoes.

When it comes to fish, the choice depends on the climate and available volume. Carp, trout, perch, pikeperch, and even catfish can be raised using aquaponics, offering a wide range of options.

Getting started with outdoor aquaponics comes with challenges that must be anticipated to ensure the system's success. Temperature fluctuations are one of the main challenges : a small kit will be more sensitive to rapid changes, while a greenhouse better protects crops by creating a more stable microclimate. Water balance also requires regular monitoring, particularly of pH, oxygenation, and nutrient concentration.

Outdoors, pests can also be a problem : birds, insects, rodents, or even cats and herons attracted to the fish. Simple protections like netting, polytunnels, or reinforced shelters can limit these risks. Finally, keep in mind that aquaponics relies on a fragile ecosystem, which takes time to stabilize. Patience, consistency, and careful monitoring are therefore essential to transform the experience into a lasting success.
