Yes. Seed germination rate drops off after the first 5 years but you SHOULD be able to get some to germinate!!! OMG!
Okay. Seeds that old are a responsibility, grasshopper! This IS totally Indiana Jones shit right hurrrrr. Do you have grow experience? Get yourself some shwqaggy brick bagseeds and PRACTICE the heck out of your germ technique and get plants to 5 nodes healthy before you try to germ antique beaners! That is SO COOL you lucky bastard. Dammit I wish my dad had been a travelling stoner!
