Not every greenhouse needs misting. Four questions decide it.
1. How low does noon humidity go?
For brief dips, ventilation and shading are cheaper. Consider misting only when humidity stays below the crop range.
2. Can you control disease risk?
Long humid periods favour fungal disease. Misting needs a humidity ceiling and enough ventilation.
3. Is water quality stable?
Hard water scales nozzles within months. Filtration and a cleaning cycle are part of the design.
4. Who maintains it?
Without routine cleaning, the system degrades into “spraying but not atomising” and wets foliage.
