Just empty the water via the controller and pour in new water.
herbie the love bud Reviewed by herbie the love bud on . Flushing waterfarms with controller setup How do you go about flushing your plants on a controller + waterfarm setup? I am gonna get a controller but want to know if there is a special way to flush the waterfarms without having to disconnect them and flush them individually. I currently have them seperate from each other and have been flushing each ones hydroton and rinsing out the reservoirs in the bath tub. But now that I'm wanting to use a controller.... obviously if I try to rinse each one seperately, I would have to disconnect Rating: 5
