Hi, Chris,

Yeah, 3/4" pvc end caps.....drilled 1/4" hole.

I'm considering trying new caps with a saw cut across the top. That would give me about a 1/16" x 1/2" opening that I think will give me smaller droplets for better evaporation. Downside is that I'll lose some altitude (goes up about 20-22 feet right now) so the droplets won't be exposed to the air as long....might end up being less effective...I dunno.

The cooler water is a remarkable improvement.
