Myth. I have some cuts that I have been doing this with for a couple years. No mother plants, just cloning the clone of the clone of the clone on and on. I'm nearing 40 times with some of these strains and there is no difference from the original.
no they dont get weaker
if you are a grower or smokers of any one genetic stran
over time your body will build up a talorance to the gene
when you get stoned your body is under attack
and the euphoric high feeling you get is your body counter acting to the attack
over time your body gets stronger and able to beter fight the weed
so in a way the person smoking the same genes all the time to them it will get weaker
but if someone who never had that gene smokes it they will be way more blazed then you
Clones of clones of clones eventually become genetically unstable some take longer than others depending on strain,I usually get tired of a strain before any probs,and if I really like the strain like really like the strain I'll keep a mother....
I have growing the same strain for about 3 years and am still making clones from the original 2 clones I got then. They came from a guy that had been cloning the same strain for about 3 years before me. That is six years so far. No difference that I can tell.
I don't see why not. I clone from clone as well. Never noticed any changes that weren't positive. I say that because I've gotten better at growing this strain with each iteration I grow.
