hey bud, i'm a fellow ebb and flow-er. I use rockwool and hydroton too. One time i put 4" cubes in and buried them (they got flooded halfway)... big mistake. they got overwatered, i lost 1 plant and the other 2 suffered in yield. now i use 1.5" started cube set right above the flood line. hand water the first few days until the roots drop down. i'd start by i'd flood 2-3x per day, 15 mins each. the less rockwool you use the more you can flood. i flood 4-5x per day.

I run a diy flood n drain. I cut a piece of plywood to fit snug inside of flood tray with holes for my 6 in net pots. The pots are suspended about 3 in from bottom of flood tray. I then put around 2 in of hydroton to cover bottom of tray.
When I set my plants in baskets I set them with the rockwool cubes about 1 1/2 in above bottom of basket using hydroton as a filler.
I then set. my drain to where just the bottoms of net pots get wet. Then as the roots start growing I lower drain level to where it only floods the hydroton in tray.
I like it this way as it keeps the root zone dark, and cool. I usually flood every 4hrs for 15 min. It's been working great so far, been using for several yrs now.

today i moved the 4in rockwool on top of my clay pellets, and im flooding 5x a day for 15min each time, im thinking about making a video today to show, do u think i have to get the rockwool wet and the roots in the bottom will get wet

Oh shit i forgot i water my table 6 times a day for 15mins i run from 7 to 7 at night so i spread the times out equally in that time period and then 1 time at the half way mark when lights r out just so the roots dont dry out to much, it goes like this 1 at 7 lights on then at 10, 1, 4, and 6 and 1 at 1in the afternoon just so the roots dont dry out hope that helps
