Fogging has many benefits for the horticultural industry. Used in seed propagation, dry fog will increase the humidity level of the germination room towards the 100% limit and yet not cause excessive wetting of the product.
It is likely that only one or two nozzles will be required within a germination chamber as the rooms tend to be virtually sealed and therefore retain moisture for significant periods of time. Accurate humidity levels can be maintained by the use of a humidistat controlling device.
The use of sonicom nozzles are even more dramatic when introduced to plants under glass or poly tunnels. Large growing areas can be completely fogged - raising humidity, cutting down severe direct sunlight and cooling the houses by as much as 5°C.
