Trading sativa seeds with other growers is how a lot of rare lines stay in circulation, and there are unwritten rules that keep it working. Labelling packs with the source, generation, and date is basic, as is being upfront when a line has not been tested or might carry a herm trait.

Sending a few extra seeds to cover germination failures is common courtesy.
