Automated Watering System for the Greenhouse

If the humidity level in a greenhouse isn't kept down it invites problems from
diseases. Some very sophisticated greenhouse operations use overhead misting
successfully, however they are able to remove the moisture from the air quickly.
Mist at your own risk.

We do not recommend an automated watering system, beyond a small sump pump
sitting in a 55 gallon barrel and attached to a hose and adjustable wand. This
applies water, not a fine mist, and it is done by hand, but somewhat faster than
the can with holes in it.
