Trident - Model T3A 18-49980 $ 332.40
• The Electronic Leaf works by using
the weight of the water on its artificial
leaf (screen)
• When the artificial leaf is weighed
down by accumulating water, it shuts
off the solenoid valve to stop the
mist cycle
• As the stainless steel leaf dries out
and rises, it turns the solenoid on,
allowing water to flow through the
mist nozzles
• This simulates the natural wetting and
drying of a leaf surface and can be
easily adjusted for greater accuracy
• The Electronic Leaf’s screen works on
the natural principle of watering when
needed and not relying on the grower
to work out a “timed” schedule
• The unit comes complete with a 24-volt wall mount transformer
that plugs into a 110 v outlet, and has 20-feet of irrigation wire for
a 24-volt solenoid to be hooked up to the unit
• For solenoid valves, which are sold separately, see pages 389-399.
• The stainless steel Electronic Leaf is made to last in the harsh, wet
environment of the greenhouse
