Why not?

First, i wouldn't trust the current industry to produce a true homozygous pair of plants with any consistency. Second, are the diaries in your profile representative of "true breeding" cultivars? Those plants aren't helping your cause. I'm not keeping mother plants. I only take clones to dabble in making some fem seeds. It's a hassle and a cost to maintain mother-plants year-round indefinitely. Having smoked for over 30 years at this point, i think i understand the range of quality that is possible. A minor incremental different or slightly more consistency is not worth that hassle. Also, to get a true breeding plant, you have to inbreed the plant quite a bit and outcropping/outcrossing plants are significantly impacted by such breeding practices. "genetic depression" i believe it is called. i like a little diversity. I don't give a shit about names or reputation. If a batch of seeds gives me slightly different phenos and good quality, that's a good thing. I'd rather have robust plants than homogenous results with a chance of some inbred depressed plant. Unless they have mapped out all the alleles and using that to determine which traits will be displayed in offsprint and in what ratio, all this talk about homogenous genetics is a fairy tale. You can't make something if you don't discern it in the first place. Saying it's a 'true breeding' plant doesn't make it one. I've never seen any sophisticated genetic mapping or attempt to figure out how each trait is defined. No punnett squares, no observing traits and frequency to help deduce underling genetic code... so, without that, they are just making shit up when they say they created a homogenous true breeding plant. This sounds more like the advertising term, "organic." No real causality behind it, but a whole lit of faith and belief. A whole bunch of things projected onto that word that have nothing to do with what it actually means. Unlike "organic," "true breeding" does have a solid definition that means something specific. I just doubt it's being met by this amtuer-hour marijuana industry run by mostly anti-intellectuals that wouldn't hire a geneticist in the first place. Heavy overlap with the anti-vacc and conspiracy crowd, from what i can tell.

I would imagine it's the amount of space needed to find them killer plants is why not many do there own breeding programs. I have seen the occasional diary where someone has done it but only had a few plants to choose from.

I'm completely new to this field, but very interested in the topic. So if you have any tips or insider knowledge, please share it with me. I'm eager to learn and try new things. 🙏😇

Because most people don't have the time, space and laws to do any breeding.
