Mist Propagation
This is an area of irrigation that we have long been specialists, many of the
large mist irrigation schemes in the UK are E.J. Woollard installations. We
recommend the supply of Mac penny control units and electronic leaves, used with
brass snap action solenoid valves. This equipment operating with Amber mist jet
nozzles is unrivalled for maintaining a film of moisture over the leaf surface
of cuttings or young plants.
The mist control unit has a built in transformer, which provides a 24 volt AC
power supply to the solenoid valve installed in the pipe work on the mist bench.
The electronic leaf is positioned on the mist bench and wired into the mist
control unit. When the leaf is dry, it signals the absence of moisture on its
surface to the controller, which opens the solenoid valve. The duration of the
mist is adjustable from about 3 seconds; the moisture that lands on the leaf
closes the solenoid valve. The control unit can be overridden to allow the bench
to be flooded.
