Why air is crucial in greenhouse farming
In the controlled environment of greenhouse horticulture – think temperature, light, watering and nutrients – the importance of air and its proper distribution is sometimes underestimated. Yet an effective aeration system in horticulture plays a silent but decisive role in the success of any crop.
Without sufficient oxygen in the water, roots die. Without air circulation, problems with stagnant water or nutrient solutions arise. And without adequate CO₂ in the greenhouse air, the plant lacks a fundamental element for growth. In short: optimal aeration is indispensable.
What exactly does aeration in horticulture mean?
Aeration in horticulture is the process of introducing and effectively distributing air into water, substrate or the greenhouse air itself. This serves several purposes, including:
- Enrich nutrient solutions or basin water with crucial oxygen.
- Prevention of downtime and algal blooms in storage tanks.
- Optimizing root health, especially in hydroponics.
- Even distribution of air for efficient CO₂ enrichment in the greenhouse.
- Support biofiltration and beneficial microorganisms in biological cultivation systems.
Aeration systems range from simple air stones in a drain pan to sophisticated air distribution systems with blowers, manifolds and dedicated air hoses.
The essential role of aeration for your crop
Air is more than just a means of transporting oxygen or CO₂; it is a functional and indispensable part of your cultivation strategy. A well-designed aeration system contributes directly to:
- Optimal oxygen uptake: Essential in substrate crops, NFT or DFT systems.
- Healthy root development: Oxygen-deficient (hypoxic) root zones lead to stress and reduced growth.
- Prevention of biofilm and stagnant water: Active moving water stays cleaner and healthier.
- Activation of beneficial bacteria: Important in organic and recirculating crops.
In a competitive market where every square meter counts, a stable and efficient aeration system can make the difference between good and optimal yields.
Aeration Solutions: From compact systems to complex installations
No greenhouse or growing system is identical. Depending on the crop, the existing installation and the available space, various aeration solutions are possible:
- Compact blowers with one air connection for local aeration.
- More powerful side channel blowers with manifolds for multiple beds or basins.
- Systems with flexible hoses and manifolds for air distribution over several sections.
- Aeration with time control or fully integrated into the climate computer.
Often aeration is added to or expanded within existing installations. Especially then, custom aeration and deep technical understanding are crucial.

Application areas of aeration in horticulture
BBel ventilation in greenhouse farming is broadly applicable and essential in such areas as:
- Vegetable cultivation (e.g., tomato, cucumber, bell bell pepper): Oxygenation in drain water or feed tanks.
- Floriculture and cuttings production: Promote stable and healthy root development.
- Vertical farming and hydroponics: direct aeration of nutrient solutions.
- Storage basins and daily supply tanks: Prevent stagnant water and algae growth.
- CO₂ distribution in the greenhouse: Through specific air ducts or integrated into ventilation systems.
Effective aeration is applicable in both high-tech greenhouses and more practical, semi-automatic systems.
Choosing the right aeration system: What to look out for?
An efficient aeration system begins with the careful selection of the blower. Important considerations here are:
- Required air flow rate (expressed in l/min or m³/h).
- Number of aeration points and the resistance to be overcome (the pressure loss in the system).
- Noise standards (relevant when placed near other workplaces or residential areas).
- Operating time (continuously or periodically enabled).
- Availability of maintenance and spare parts.
DOVAC will analyze these factors with you to ensure that the system you choose fits seamlessly with your specific business situation. ensures that the system fits your practice.
Maintenance and reliability of your aeration system
Because aeration often goes unnoticed, aeration system maintenance is sometimes overlooked. However, regular inspection and maintenance are crucial for reliable operation:
- Filters can become clogged, reducing airflow.
- Hoses can calcify or wear out over time.
- Blowers benefit from timely maintenance for maximum longevity and efficiency.
DOVAC not only supplies the necessary parts, but also advises on optimal maintenance intervals and supports the optimization of your existing aeration system.
Conclusion: aeration as an engine for growth
Aeration is the invisible but powerful engine behind healthy crops and profitable cultivation. It enhances root development, keeps nutrient solutions vital and contributes to higher yields, often in an energy-efficient manner.
With the right blower and a well-designed air distribution system, you will make a difference – not only underground, but also visible in your bottom line.
