Just made the switch from rockwool to lava rocks. lava rock people out there are you all doing a constant flow 24/7 or interval, maybe 20 mins every 1.5hours

Hi Boxmunch. I was looking into lava rocks as an alternative to hydroton - most reports I read said that lava has excellent air cation exchange capability, so you can run them 24/7 like you would do hydroton. Am sure someone with lava experience will chime in shortly :)
