The Doomsday Seed Vault on Svalbard has over 21,500 cannabis seeds in it. That means that there are more seeds in there for weed than there are for aspargus, blueberry and raspberry, for example.
@Radu You say that like I have time. Which I do, but it's not a whole lot of time. In my free time I check up on SATW, check up on my RTS's, and then watch youtube for the rest of it until I get back to work.
