Makes it hard. You can't really have anyone send you any because of customs declarations.
Look on the introductions forum and there was a guy from yakima, wa who's family owns a hop farm. He might be able to help you out or guide you in the right direction.
I think I'll wait until we're in a house. We're in an apartment now but I could plant one or two plants outside here. If I *were* to try seeds though, I think it'd be better to be in a house so I could plant a lot more plants, eliminate the males then make little extract batches to try the various hops produced and select out plants I like. Could be interesting. But that'll have to wait. We're saving for a house but still have another year or two to go.
