yeah rock wool holds alot of water and is good for seedling. Dripping is a good idea so when they get to that magical 5 node like 6 inch tall stage check them before the drip starts and check how wet it is, you want it to be at the point where its wet about an inch down *remind you this is when you go into like a 5 inch deep medium* if its still wet on top adjust your times
