Ok I am in misting system hell... to the point I am asking myself why I started this project. I have bought a ton of stuff, and am still trying to figure out where or what type of bulkheads to use for my drains. Any ideas? I have a 27mm drill bit I am planning on using and have found a few 1 inch bulkheads, but what type is best? The ones without the barbed ends on then how do you hook up a tube to them?
