bonghopper - grafting a soft-trunk/branch plant like cannabis is very difficult. Grafts are usually done using woody growth so as to either wedge a new bud of the plant to be grafted (scion) into the cambium layer of the stock plant or to do a "cleft graft" where the cambium layers of both the scion and stock are joined.
Doesn't mean it can't be done, but it does mean to expect many failures along the way.
This will likely be a great starting point for research -- http://en.wikipedia.org/wiki/Tomato_grafting
