Timer

These are perfect I have them on multiple hydroponic devices to make sure the water is doing what it needs to do perfectly not just my Towers

Works as advertised. This was a replacement for our original that stopped working because it was accidentally left in the basin of our flex tower over the winter in storage. Because it was outside, it got water in the basin. So lesson learned, if you are not using your flex tower, take the timer plug inside.

Awesome product
