How long do air stones last in hydroponics?

Your air stones should last you at least six months, but many hydroponic gardeners use them indefinitely. Simply use a bristle brush to scrub them clean on a regular basis to prevent clogs and buildup.

Should I leave my air stone on all the time?

Yes! Plant roots need oxygen to properly function, so they don’t really need a rest from the bubbles.
