If its a "unique pheno" then you can't sell people seeds a say here is GSC.
Well, in fact, you can say whatever the hell you like, and that's the problem. .
Its "caveat emptor", unfortunately, with the onus on the buyer to make sure they're buying from someone trustworthy and know what they're getting.
Not knocking on Swerve personally, but this is one major reason I'm not buying "Girl Scout Cookies" from him or anyone else, until/unless I hear that the GSC "ceeds" are great in their own right. I might be willing to be a beta tester in some cases, but I'm not willing to shell out top dollar for the "privilege". If GSC S1 (or whatever) is so awesome, it will be equally awesome in 18 months, and I'll buy it then.
Even if its a rare pheno that shows up in 1:5 ratio you can't sell seeds and say here is GSC. Especially if you selfed a GSC to get those seeds.
Again, not only "can" you, but this, unfortunately is the standard in the industry. Lots of ceed-makers are doing exactly this.
I don't have any problem with someone selling me S1 ceeds of a "clone only" line, so long as they actually are selling me real S1 ceeds of the line in question and make clear that that's what they're selling. In fact, I'm actually growing out something like this right now (see my sig, below), and so far I'm pleased. . .we'll see how it turns out shortly enough. If the seller is truly "stand up" they'll have tested their line and say right up front if the thing puts out different phenos, how many, and which ones (if any) are like the original. Unfortunately, very few growers are actually doing this.
What people will give up their money for these days boggles my mind. It takes zero effort to just look at two good strains and cross them and sell untested seeds. It take even less effort to self plants and sell those seeds untested. The only effort this guy puts into anything is coming onto the internet to "defend" his garbage. So people seeing him defend his shit just assume that he's legit. Then when people have problems with his hermie weed he just accuses them of being a shitty grower. I mean I've never grown the guys shit but I know people who have and were not pleased. It really doesn't take a wallstreet shark to see how the dude operates.
Not attacking anyone in particular here, but this is a common MO amongst a number of so-called "breeders" now. Find a bunch of someone else's "elite" clone only strains that have a reputation, get them, cross or self them, make ceeds, then hype the crap out of the ceeds. The art here isn't "breeding", since this is not breeding in any sense of the term; the art is in PR and selling the product. In some cases "breeders" are claiming provenance over lines they had little to nothing to do with creating (eg "purple" lines; see above).
Here are my earlier thoughts on this; Racerboy is right, there is some good stuff in the rest of this thread, too:
