depending on how long they were in vermiculite would depend on what roots developed. Then the transition to areo would confuse them. Plants develope roots for what kind of soil they are growing in or water. changing back and forth can be done but is stressfull.
When I do clone for soil peeps they have to take them at first sign of root and they do well. I used rockwool and the root riots for years but found in hydro it cause problems keeping the stalck too wet. So all natural areo cloner and let me tell you it was a bitch for me to get a handle on it. I had to find just the right place for it where the temp is always good.

Good Luck and this is the hydro section so if you want to talk areo it's good.
