Grafting a sativa cutting onto a vigorous indica rootstock is a niche technique but it works and it solves the slow rooting problem these lines have. The rootstock supplies a strong established root system while the scion grows true to its own genetics above the graft. There is a photo walkthrough of a cleft graft on https://hazesativaseeds.com using a Haze scion on a Kush root, with notes on humidity and support during the healing week. It is fiddly, but for keeping several rare lines on one root system in a small space it has real uses.
