they look great...I didn't wait for pik to load, because it was taking too long...must be too big...anyway, the water in a bubbler should be 1/4-1/2" below stem.
I would transfer all of them to the hydro system or pots that you are starting them in...they a ready. get'em growing. some guys put there's in sil as soon a any roots pop...I like to get them healthy like yours look and then pot them...goodluck lw
