I have DWC setup of 8 bubble bucket. I have as many as five going at one time, with some in grow and some in flower state. It is a lot to keep up, with changing and cleaning weekly. I am looking at converting then into a ebb & flow system and have some questions.
How long can a E & F setup go before water change out?
Should the water level reach the basket?
How much water should be left in bucket? just cover some of the roots and keep air stones running?
