Plants want humidity that moves with temperature — the practical control variable is vapour pressure deficit, not a fixed relative humidity figure. A system that holds 70% RH regardless of temperature will be too wet in the morning and too dry at midday. Controllers driven by temperature and humidity sensors, adjusting each zone, are what make fogging useful rather than risky.
Fogging at 1–15 μm evaporates in the air and raises humidity without wetting leaves. Coarser spray deposits water on foliage, and prolonged leaf wetness is the classic route to fungal disease. This is the single specification that matters most, and it is why high-pressure systems are used instead of low-pressure nozzles.
Please send: greenhouse dimensions and type, crop, target humidity or VPD band, ventilation arrangement, water source and quality, and power available. We return nozzle layout by bay, zoning, filtration specification and consumption figures (published 3–8 L/min), with a control package that follows plant demand through the day.

Yes — the same evaporation that raises humidity absorbs heat. In dry climates growers often specify fogging for both humidity and summer cooling.
It is the main maintenance risk. A 5 μm inlet filter and a cleaning interval are specified with every greenhouse system; where water is very hard we also recommend pre-treatment.
