Lookin pretty good. I have the same type cloner and it usually takes about 2 weeks for good roots to be showing. You could mist but I dont bother since water is constantly hitting them. Also you could cut the leaves in half so that the plant wont work as hard on breathing and create roots faster.
Same applies for clones as seeds. They are easy to make into moms. I grow soil so I just transplant when enough roots and they take off in a few days into a large plant just like the seed they came from. Of course pinching helps to give you more growing shoots to clone with.
