That may work, but I find that germinating in wet paper towels in a mason jar in a dark location for a few days prior to insertion into the rockwool cube, speeds up the process. Slit the rockwool cube open so you can insert the cotling into the wool without damaging it and then put it in the netpot surrounded by hydroton rocks, and insert it into your Bubbler or whatever Hydro medium you are using.Hey big...
yes... rapid rooters and rockwool can be used in almost any system...
You just put the seed in a soaked cube and it will germinate and grow!
