Active Dehumidification
Why Dehumidify? Before discussing the details of dehumidification, it is important to understand why it is important to control humidity within a greenhouse at all. When humidity is low, evaporation rates increase which can cause water stress on the crop and will raise humidity regardless. Photosynthesis is optimised at a relatively high humidity level, as…

Greenhouse dehumidification
With rising costs of energy and pressure from retailers to reduce carbon emissions, controlled environment horticulture (CEH) has been moving towards even higher efficiency production in glasshouse models. This often comes in the form of ‘closed’ or ‘semi-closed’ designs. These systems minimise air infiltration and attempt to maintain an indoor environment to maximise the effectiveness…
