I always thought it would be cool if you could see the entire lineage of a weed jar at a seed lab. There is so much weed in circulation which has it's roots from long, long ago. It would just be interesting if your analyzing weed you found on the street, but it could also give weed much more incentive to be sold to players. Old weed from two years ago could become a collectors item, or perhaps weed with massive lineages could gain value.
