Shit, honestly anything haha. An awesome guy sent me a bunch of old sensi (and others) seed catalogs from back in the day so I've been able to learn a bit about some of the older stuff like silver haze, northern lights, original skunks and afghanis, etc. I'm a big sativa guy so being able to hear about how some of the strains we see today came about is awesome, the problem is I don't have any specific strain(s) in mind
It's also cool to hear about the old school growers and grows, really just getting an idea of the history of the plant and what the world was like 30-50 years ago. Anything you want to share, even if it's just random stuff, would be awesome. I'm one of those people who tends to go "all in" on stuff I'm interested in so every little tidbit is cool to read about.
