Hand watering rockwool pots?

Hey me and another other guy had a question. What would rockwool pot outiside of a ebb and flo table be like? Just dunk each pot or better yet just water reg over the plant like a soil plant? Any experience like this? I have one clone in a rockwool cubed medium net pot. I have benn placeing it in a pan filled with water and nutes once a day before lights on for a few days. It seem to be going ok, still getting the water down right/

Any ideas?WHY NOT?
