I have a diy cloner like that also I found if you use the net cups with rapid rooter sprayed 1 time a day for 15 mins they root in under a week as soon as they show roots I pull them out and put them in a small ebb in 4" pots till they really develope roots but you have to get them out asap from the cloner cause bare roots getting sprayed once a day dry out quick but if you spray the rapid rooters more than once they take longer to root.
