"Hey, wanna smoke some man-goo" is one of those questions that can go very good or very bad in an instant...
Yeah, it's like that strain Cat Piss. Nobody who doesn't know what you're talking about doesn't want to get involved.
And from what I was reading in he link posted earlier, the breeding technique you were talking about is called cubing. Basically the idea I got from the post was:
Find a momma and a poppa (different strains usually), and identify a trait or traits you like in each that you would like to pass on.
Grow the seeds you made and pick out the ones with the traits you wanted and don't breed the ones with traits you didn't want. When the ones you like are ready, breed them with their original parent. Gross to humans, good for buds.
Do the same thing with the next generation. Keep the ones with the traits you're looking for (smell, bushiness/height, nug density/size, etc.) and breed them with their grandma.
Do it one more time. These kids will end up breeding with their great grandmother. I guess you could call your original mom strain a matriarch. It's called cubing because the plant is multiplied to the power of three. Damn nerdy-ass mathboys.
Basically they say that by the third generation you'll get a strain that produces the plants with just a few different phenotypes. Kind of like how a dog can give birth to different colored dogs in one litter but they're still all the same dog. Same goes for bud. A purple strain doesn't always turn purple, it's just a particular phenotype. I suppose if you kept breeding past three you could isolate purple buds, but I'd be afraid of sacrificing other things I wanted.
That's kind of an oversimplification considering I have never bred, just read, but there ya go.
