Review on Automatic Humidifier Adjustable Aquaculture Hydroponics by John Roberts

A neighbor gave me one to replace a broken brass valve. The chlorine and Florida sun are bad for plastic floats, and over time they will crack and fill with water, rendering them useless. Replacement floats for my previous model are no longer available so you have to buy the whole brass assembly. Turns out this thing is just as good as that and I can buy 6 of these floats for less than the original! If one fails, I just change the whole node. I hope they last about a year and I can change them every year just before summer.
