If they were mine, I would score the base a couple of times, brush on either dip n grow or clonex, repot and most importantly be patient. Seeing the parafilm has been removed, you may have to control the humidity with either a dome or a covered bin. See how they do on their own first though. It is going to take way more than eleven days to see any root growth. Anything rooting in a week or two, in my opinion, is a super rooter and a bit unusual.
