I hope with the pots you bought for your clone, you have drain holes so you can see the rooting coming out. I would suggest using a stierofoam cup and poking holes in the bottom, you can see the roots once its rooting. Of course, when you see it rooting in the cup and you dont see much dirt left just all roots, then you can transplant, I wouldnt suggest doing this earlier if the cup is not filled with roots.
