prob more because you smoke it too much.....than the cut actually loosing potencyi have been growing for years, and so has a close relative. He takes clones of clones and only grows the same plant.... many of them...same plant for years.....and I have honestly noticed an extreme loss in potency on the strain over the years
XClones do get old and will lose vigor regardless of whether you keep a mother plant or take a clone of a clone. The heart of the problem is very simple, old age. Like all living things, as our beloved plants age they slowly accumulate genetic defects during the countless times their cells split and reproduce over the years. Think of a human being. A human at age 90 has the same DNA blueprint as they did when they were 20 yet the 20 year old will always outperform the 90 year old version. The same is roughly true of plants.
If you want clones to plant a new grape field for wine, do you think it makes a difference if the mother vine to be cloned is from a young plant or 100 years old plant? Does it need to be from seed (the old mother plant) or can you clone a clone from a clone from a clone etc, from a new seed plant and get the same results each time?
There is the potential for a slightly quicker aging and degradation of the cut if you keep taking clones of clones simply because when people use this method, each time they take the new clone it is after the plant has been forced through very rapid growth in veg. Where as with a mother plant, people tend to leave them in intentionally poor growing conditions such as low nutes and low light so they both grow and age more slowly.
The shorter the plants natural life would have been, the faster the cut will show its age.
At one extreme you have Ruderalis strains which really can't be forced to live beyond the single very short growing season they have adapted to live their entire lives within since they originate from very high latitudes with short growing seasons.
WRONG, Ruderallis can be cell cultured or callus cultured and they live forever.
Indicas cuts age much better than the Ruderalis, but they still are not naturally long lived plants since most originate from temperate latitudes with harsh winters. From what I have seen a very indica leaning cut will tend to go noticeably downhill after about 5 years or so and at 10 years its very evident that the plant isn't what it used to be. When a cut gets old it usually won't effect the quality that much but rather the vigor of the plant. You end up having to veg it longer and longer to get the same yield you used when they were young.
Never saw this with any of my hundreds of clones I have had for 10-25+ years now WLD, NLD, WLH, NLH.
Tropical sativas which naturally have life spans that are not limited to a single growing season are not surprisingly the cuts that age best. I have heard of old tropical sativa cuts that are literally decades old and still alive and kicking.
Sativas are not limited to being an annual plant? Even if grown up North in the snow?? Or just on the equator? They are an annual.

Hybrids tend to fall somewhere between pure indicas and sativas.
