I was only talking to some one the other day about this, he works in Conservation, replanting wild places with local growing plants and seeds. Then we got talking about bringing back extinct plants, or seed held in seed stores that may or may not germinate. We then went onto how to rejuvenate old seeds that had seen better days. The gent went on to say that they had some really good results by adding a couple of drops of veg oil into a baggie, chuck in the seeds, give it a shake, wella! He said the veg oil puts back the oil that would be in the husk of the seed, said with out the oil the hinge on the seed won't work, so can't crack, so this ties in with people biting their old seeds. And it stands to reason that and oilly seed like hemp must need the oil, so maybe there is some thing in what he says, if anyone tries it and has success with this method, hit me up and let me know.
