starting a germinated seed in hydro... rockwool?

after my seeds have germinated can i pop them in rockwool and then put that in my hydroton setup? or will this be too much moisture for them?

after you put them in rockwool just throw a cover over them until they come up 1-2 inches or they have roots out of the bottom. Thats when i throw mine in the aero tub. Good luck

ah alright. that makes sense. knew i was missing a step.
