@GMan I think that's a great idea. @8k_feet and I have talked about setting up a meetup group to discuss and teach home growing here in Colorado. I think it's important to help teach people in states that have legal home grow laws.
From an advocacy standpoint, having broad support for home grows will help to create sane federal laws when the US is ready to pass legislation. I think most of us here wouldn't favor legalization without some kind of allowance for personal grows. A lot of the voting public doesn't necessarily 'get' that aspect of legalization, and that right will probably be targeted in big money politics.
And from the genetics point of view, most of these people (home growers) will be exploring further into the cannabis gene pool than the regulated med/rec markets. I think people like us, growing and sharing seeds, finding and preserving old and new lines, or even just our natural curiosity in creating demand for unique cultivars, is or will become the primary driver of genetic diversity.
Take me for instance. I had no idea about Congolese strains. Watched a Vice documentary a few years back about searching for cannabis in the Congo, and thought it'd be really awesome to try. Found @bodhi had this Jungle Spice strain, and decided to give it a go. Lo and behold, the strain really resonated with me, and I immediately felt that I'd never want to part with it. Found this preservation project about the time I joined OG a few months ago and bladooowwww, here we are.
Next stop for me on this train is an IBL of JS, and more experiments with Congolese genetics (or what few are available).
