Faq's needed about plant generations

I have 2 different strains going.1 is on its 6th year(Blueberry),started from seed, and another I got 10 years ago(g-13) as a clone and don't know how many generations its been through.If anyone has or knows info about effects of older generation plants,please share.I'd rather not hear," I heard this" ,just some good facts

My perception is that as they get older they take less flowering time and the smell calms down a lot.I wouldn't say they lose any potency tho and have plenty of trics on them.My g-13 is pretty much ready by the end of the 5th week of flowering,never goes past 6 weeks.My blueberry when i got it, took i'd say about 8-9 weeks to flower and now i'm down to about 7 weeks.I just started using co2 this time and just finished week 4 of flowering the G13 and its about done,I'm sure by the end of the week it will.

The more stable the strain, the less it is going to 'drift' over time... Blueberry (original) is on the stable side as I understand. But if you are selecting for shorter flowering times by using the seeds off the quickest plants, that would explain your drift.

You mean you have a clone of a clone of a clone etc that was ten years old? I think the genentics should stay the same and the plant should just improve. But if you got 10 yrs experience with cloning You already have heard that before. It says the same thing in every marijuana growing book.

I have read that there is a 'drift' over generations of clones, that they lose potency and stability after awhile ... NOTE: I do NOT know that as 'fact', I have only read it somewhere in my research, so take this comment with a grain of salt ... :smokin:

The way I understand the cloning drift, it's a problem with DNA/RNA repair at the cut sites of both the mother and the clone.

Obviously the plant is stressed when it's cloned, and some of its normal life processes can malfunction, introducing mutations to the DNA. Mostly they will be unnoticeable, or if they are major, the cutting might just not survive, so you wouldn't notice...

But over a long period of time the sum total of all those small mutations can build up to the point where the grower would notice drift.

Anyway that's just how I understand it, and why I'd be more likely to keep just a couple old mothers, and regenerate them only every coulple years, rather than clone-of-clone-of-clone...
