Rockwool to pellets question

This is such a newb question but I gotta be sure.

Running a bucket ebb & flow system.

After germinating a seed, and I get 1/4" sprout, do I put it in a 2x2 rockwool cube and then place the cube into my bucket full of pellets?

Then hand water the cube, but dont run the pump until when?

bump

Still hoping...

Not sure with the ebb n flow, but that sounds right to me.. Same as a drip system for the most part I think.
