My sentiments exactly. I'm not a big believer in the whole you'll use up your genetics Idea. Same plant, New tissue from the old, New Plant equals no problems. There could be exceptions but I just don't know....
no drift stil the same plant and the exact genetic makeup some of us need to read and do a little trial and error befor they answer not trying to be a ass or anything but please people genetic drift how could that be please explain and I'm all ears.I clone tomatoes roses and anyother plant around and I hjave never had genetic drift.My partner has a 27 year old skunk plant that still kicks out some lovely ladies and there still is no drift maybe 30 years in just maybe so have fun find a mother that ya like and keep that bitch until your old and gray.
I don't know about Urban Legend but I've experienced what I would call genetic drift -maybe-. I had a Sensi Star girl for years that I took clones of clones of clones (over and over). Years later this girl did not yield as well, did not taste as I remembered and generally sucked (may have gotten disease who knows) but I'm assuming it was drift cause all this happened over time. This was my best girl... She would yield 1/4 pound per plant for a 90 to 95 day cycle (my biggest/best plant ever...amazing - I think some people call this pheno the Ogre). After 5 years I couldn't get her to give me more than 1.5 zips per plant (grow room, nutes and other strains stayed the same so I don't think it was me). Just my personal experience...like I said, may have been a pathogen but I don't think so.
-EDIT-
but to answer your question...
it's perfectly fine to take cuttings from cuttings. No worries
i have been using the same clones for 2 years now and refresh my moms every 3 months and i have no problems with genetic drift.Its what the guys at the seed stores want u to think so u buy more seeds. peace
