Greenhouse humidification in the Netherlands and Germany

In high-tech glasshouse horticulture the climate computer runs the show. The question is whether your humidification can be driven by it, precisely enough to be worth having.

Control integration is the specification

A humidification system in a modern glasshouse is only as good as its control interface. What we supply is a system that responds to sensor input zone by zone; the settings come from your climate computer and your crop strategy. Two practical points decide whether it performs: sensor placement (away from nozzles and vents, at crop height) and zone granularity (a compartment with a different crop, screen or shading should have its own zone).

Fogging versus other humidification methods

Pad systems add humidity only where air passes through them. Boom and sprinkler systems apply water to the crop or floor. High-pressure fogging adds moisture to the air itself, at 1–15 μm, so it evaporates before contacting leaves — which is the property that matters where leaf wetness drives disease pressure. That is also why droplet size, not water volume, is the number to settle first.

  • Zones by compartment, controlled from the climate computer
  • Nozzles positioned above the crop, into the air stream
  • Water treatment as required — reverse osmosis water is ideal and common in this market
  • A maintenance routine for filtration, because fine nozzles are unforgiving

What we need to quote

Compartments and dimensions, crop, target humidity or VPD band, existing climate control and how it communicates, water source and treatment, and the power available. We return nozzle layout per compartment, zoning, pump selection, filtration and the expected consumption (published range 3–8 L/min). Where your climate computer has spare relay or analogue outputs, we will tell you what interface is needed; where it does not, we will say so rather than promising an integration that will not work.

Questions

Common questions — Europe

Can it be integrated with an existing climate computer?

The system can be driven by external control signals or run from its own controller with sensor input. Send us the interface details of your climate computer (available outputs) and we will confirm what is possible before quoting.

Does it cool as well as humidify?

Yes — evaporation absorbs heat, so the same system reduces temperature while raising humidity, which matters during continental summer peaks.

Which water quality do you need?

Rainwater or RO water is ideal and common in Dutch and German horticulture. Where water is hard, filtration is specified as standard and pre-treatment is recommended — tell us the source at enquiry stage.
