would be more concerned about the effect
of this water when you’re watering and
fertilizing your plants.
If everything else is fine with your
plants and you’re simply trying to increase
the humidity in the growing area without
getting deposits on the leaves, this can
easily be solved by installing a misting line
under the growing bench or at the top of
the growing bench. The misting heads can
be oriented in almost any direction and will
still provide the needed humidity without
actually getting water on the leaves.
Inexpensive misting lines can be bought
from a variety of locations on line, and if
combined with a simple humidistat and
a solenoid can easily be automated. The
heads on most of these misting lines emit
a very fine mist that shouldn’t actually wet
the surface of leaves, unlike the heavy mist
often produced by misting fans. Misting
heads on misting lines like those shown in
photo (Fig. 3) will need occasional cleaning
to remove deposits from the solids in your
water, but are otherwise simple to maintain.
They are easiest to maintain if the misting
heads are brass.
