How to ensure consistent water quality in greenhouse tulip cultivation? The client's challenge

The client grows cut flowers in the greenhouse, primarily tulips, irises and eustoms. In the cultivation of tulips, it is particularly important that the water used for irrigation has constant, strictly controlled parameters - both in terms of chemical composition and the precise proportions of fertilisers. Tulips have specific requirements, so the client wanted a solution that would ensure the stability of water parameters without the need for constant manual dosing and adjustments. The company expected to automate the process so that staff could manage the system easily and quickly, have full control over the quality of the fertiliser mix, and have remote access to all information on irrigation parameters. Thus, not only a precise technical solution was needed, but also one that was convenient to use, saving the employees' time in their daily tasks.

How to automatically manage irrigation and fertilisation in a greenhouse? Our solution

For our customer, we implemented a fully automatic system for preparing fertiliser-enriched water, based on the JUMO variTRON 500 controller. This is the command centre for the entire greenhouse irrigation process - it collects sensor data, analyses it in real time and controls all plant components in real time.

The system is equipped with high-precision sensors for liquid analysis of pH, redox and free chlorine, which ensure continuous monitoring of the key liquid parameters and, therefore, high water quality for plant irrigation. This ensures that fertilisers are dosed with the right accuracy and that plants receive exactly the conditions they need. Two web-based panels give the customer the ability to easily and conveniently monitor the entire system from anywhere - even outside the greenhouse.

Our solution also integrates pumps and pipelines that work together automatically under the control of the system, ensuring the right pressure and optimal dosage of the fertiliser mixture. The whole system runs smoothly, reliably and precisely, making daily operation of the installation much easier and allowing you to focus on other production-related tasks.

How has irrigation automation increased the productivity of greenhouse tulip cultivation? Customer benefits

Thanks to the automatic irrigation and fertilisation system, tulip cultivation has become easier, more efficient and predictable. Above all, thanks to the physico-chemical testing of the liquid, it was possible to achieve a consistent, precise quality of the water used for irrigation, which directly translated into better plant health. The tulips began to grow more regularly and their quality increased significantly - the flowers were healthier, stronger and more uniform, which is crucial for large-scale sales.

Automation also allowed a significant reduction in manual work. Instead of preparing fertiliser mixtures manually every day, staff now spend much less time testing the water - all they need is ongoing monitoring on online panels. This allows them to concentrate on more important tasks in agricultural production, such as planning the next planting or optimising growth conditions. As a result, greenhouse tulip production is more stable, the flowers achieve better quality and the client has gained the ability to grow the business instead of constantly ‘putting out fires’ in the production processes.
