Alright so I know that there are times that you should let your roots dry out in a hydroponics system, so when you're timing your pump, how long should you leave your pump off and how many times a day?
Ok where can I find a time capable of that? lol as dumb as it sounds the only timers I can find only allow 7 on/offs a day digital anyways and thats what I would prefer to use
Homedepot has a nice 15 min interval one. It also appears to be waterproof. Everyone uses timer for their Christmas lights so they should be easy to find
