Plants need water - most plants are composed mostly out of water and the health of a plant will depend directly on the relative Humidity of its surroundings.
Leaves lose water through evaporation through their stomata – small openings in special cells on the leaf surface where gaseous exchange takes place.
If the relative Humidity is too low, a plant will start to give up some of its water into the surrounding air which will result in the plant drying out and wilting.
Pair the DHDC Digital Humidistat with a HR-15 or HR-50 for the ultimate in humidity control & matching the correct vapour pressure deficit (VPD) to the stage of growth your plant’s in.
The additional output from the Digital humidistat can control dehumidifier, or a cooling or heating appliance. This allows the gardener to have much more control over the factors that most affect the environment of their grow room, which can drastically improve results in terms of quality and quantity.
