I've been using one that my store calls "bumblebee" misters. They're black
and yellow (double shot injection molded, I think) plastic and They cost
about 50 cents. They are apparently more than just a tiny hole and run on
line pressure. They have lasted me more than a few years, easy to clean, and
if not to throw away. The end has the standard barb and thread.

To take care of dripping, you will have to use some sort of check valve
arrangement. I have one mister that is below all the others and will drip
out and let air back into the system and about eliminates dripping from the
higher misters.

Does anyone have any experience with the many types of low pressure (40-65
psi) mist/fog nozzles that might be useful for humidification and cooling?
I'd like to avoid the expensive high pressure fog systems currently in
vogue
that require a booster pump. A major plus would be the avoidance of
drippage
following a mist/fog cycle.

Thanks,

Jeff
