Agricraft Integration
It seems that Sanguimancy can be of use, even when working with advanced agricultural techniques. Both the Ritual of the Green Grove and the Sigil of the Green Grove will speed up the growth of such plants (and inhibit the growth of weeds, should your world be unlucky enough to be blighted with such a thing).
Moreover, the Reap of the Harvest Moon will keep harvested plants safe, as if you had gathered their produce with your own tender hands.
If you think you see any weeds, no you didn't. (It's a minor visual bug. Don't worry about it.)
