Mist Chamber: This is a structure used to propagate soft wood cuttings, difficult to
root plants and shrubs. Here the cuttings are sprayed with minimum quantity of water
through a series of intermittent sprayings rather than a continuous spray. The intermittent
spraying can be done easily by means of a high pressure pump, pipeline system and a
time switch. The mist nozzles are fitted to these pipelines and suitably spaced over the
propagating material in the chamber. A mist chamber of 15 square meters area is
sufficient for a nursery.
Mist Chamber
