No, because they say the thicker the cut, the longer it takes too root. Newly vegged cuts are preffered, or new growth. Cuts from the meristem, like topping for a cut root the fastest. Are you doing the basics like citting at a 45degree angle or scraping the firsy layer of "skin" off of the area, i make little slits in the stems and in rapid rooters i get big thick root's. i would try some kind of rooter and then transplant it inside your system .
