Incase any one is still looking for pure ruderalis hemp seeds I ordered some here:
http://www.thehippiegeneralstore.com/Raw-Viable-Hemp-Seeds-.html
for $5 and got a huge bag of seeds, like over 1000 lol. grew one out for fun and this is what I got. Absolutely no crystals or smell. But definitely a pure hemp auto flower. It was a pure female too, which surprised me. It didn't even hermie like the the german hemp seeds I ordered from them, pretty much all those plants were useless males or herms. But if the polish ones have more true females than they would defiantly be a good start for producing a new auto flower strain with.
didn't bother trying to smoke it or anything cause it ended up getting taken over by aphids.
but here is a picture of the amount of seeds I got for $5, lol.
Cheers
