Genetic Drift?

I think he might mean that nature culls negative traits...
If so I agree... even indoors, weakness lessen the likelihood of propagation.

That is basically what I was trying to convey. The plant is always selecting triggers when it sees stimuli, in an attempt to survive the best it knows how, and with what it has to work with. Always selecting for the best way to line up it's given map, so to speak, with the one and only parameter being to survive.

No need as far as I am concerned, except that you would obviously want to select parents which are not genetically programed to have negative epigenetic responses easily.

selecting for something which is temporary would be less fruitful than selecting away from epigenetic negatives, imho.

this is a good quote^^^:)

epigenetic negatives are an intresting subject,,,,

what could be considerd a positive epigenetic reaction???

Imho, the only thing which might be considered 'positive' in relation to epigenetic change would be no negative change from the original epigenetic state. That's why I keep saying that the only thing it really means to 99.9 percent of growers is keep your garden healthy and your environment within what we know to be ideal parameters (tweaking per individual plant of course).

what if we are allready living with a negative epigenetic effect?

would removing the stimuli for the negative reaction cause a positive action,,,,??

all this makes my head hurt, trying to follow..........

i think what you might be saying is that environment issues caused my strain to mess up?

the kushberry happened at a completely different grow spot.

i only take clones from healthy moms, and only healthy clones. if the moms start to "wood" up, i toss her.........

Clones don't change, they don't drift. I have clones more then 20 years old that are still the same as year one. Yes in theory it could have a mutation, but that is rare and wont happen to back up copies, if you keep them.
What clones do is pick up viruses and then they can lose vigor and yield. They can be cleaned up of some viruses by fast growing, or special treatments, and then the taking of very small meristems to be grown in-vitro or rooted virus free.

I know what you mean Krunch, my brain has a hard time with it all.

yes, it is most likely something affecting the plant and not a mutation.

If it were fungal or viral, for example, then it could easily be transmitted from one area to another before it ever manifest any changes. For example, by the time you see a spot of powdery mildew, the pm has been living unseen below the leaf surface and undetectable for quite some time.

Viruses can go undetected for quite some time too.

Lower branches grow slower and become infected faster. Tops often grow fast enough to outrun negative external stimuli. That's why I was recommending taking cuts from the top of the meristem, to see if you could reverse the issue back.

But they're not. As the research Head posted explains.

No they are not. Have you not read any of the thread you are contributing to?

Epigenetic changes are not always heritable.



This quote seems to be misleading you. Darwin is talking about adaptation of a species, not talking on the level of the individual. Don't let the terms confuse you. If you had to start carrying the brick hod all day at work, your body would adapt by developing larger muscles and seriously calloused hands. Would that be a mutation? Also Darwin had no knowledge of epigenetics, which allow adaptation without mutation. Don't want to get down on you rick, because I admire your desire to learn but that last post made it look like you've learned nothing from this thread.

In this thread there's only one person talking any sense on a topic that his has an understanding of (but is clearly not a practicing student/scientist in the field) and that's Head. Then there's Hoosier playing internet catchup, a bit out of his depth, googling every term he reads to try to find something he can pick at.

but sometimes they are heritable, What happens if the hog carrier has a son who goes into the same trade? will he adapt quicker than someone who's background is not from construction etc? just like histones(FLC) and vernalization????

Nothing in the real world which indicates that would be the case.

when this happend to me , the only thing that was different was me getting the borg for the first time ..as soon as i got that ,shit went down hill . even when my clones were borg free i would still get "duds" here and there ...even people i passed bug free clones to had issues.

Okay, here is the way i see it. To say something has been observably the same over a long period of time does not mean that things have not changed. Just because you ran a mom and clones for blah blah years and everything is hunky dory does not reflect the potential that has either already happened or is about to happen. Usually drift is negative, as if things are breaking down, a sort of natural decay, the undoing of things over time. Nature does not allow for things to remain the same, but the schedule of change is usually way slower than we can observe. You might see a bad effect but it might be long after it happened. You guys all read Asimov's "Foundation" Trilogy?? about decay over time. It is called entropy. In biology it is called SENESCENCE, and it is real. It is almost foolish to believe that the cut someone started several generations ago has remained at its peak as the cell lines run out, time after time. Nothing in nature works that way. Now, why a healthy mom craps out I can't explain scientifically, although it makes sense to me that it eventually grows tired. But a cut of a cut of a cut, cmon, it's only reasonable that it has already changed, but the changes you eventually observe are just the ones you are capable of seeing. A lot of marijuana growers are risking huge genetic problems swapping all this poorly documented plant material loaded with viruses, drift, and lack of vigor. In the end I think seedstock needs to be used, and hybrid vigor brought back into these lines. Just my opinion though.

i have 2 dogs,,,,a boxer and a huskie

the boxer is natural guard dog,,,,she would love to rip a kids head off,,,at times she tries,,,,but this is just 1 of the classic boxer mentalitys

the huskie ive had since she was 8 weeks old,,,,she is totaly pre disposed to PULLING,,,she is by nature a working dog,,,,her attitude is also classicly huskie,,,,,she`s over friendly,Inderpendant and not house-protective , she supa distructive when board an even tho her mouth and teath make her look like a friggin wolf she is a classic huskie,,,,shes programed to work and live in a PACK,,,,,,,,, shes is a handfull and every huskie owner eperences the same issues,,,,

all huskies seem to share the same attitude,,,


both are clasic examples of how dogs have pre-disposed abilitys and atitude due to selection and conditioning,,,,



ps ,,,zippy is a weed eater,,,she prefers dry weed but wont say no to stems,,,,,,,,keep your twigs safe zippys about,,,:)

As seed makers, do you not think it would be in Sam's and Myself's best interest to push the myth of genetic drift? If it were the case that clones often genetically change, I would be advertising it as a reason to buy good fresh seed. Unfortunately, There are no grounds (certainly not senescence) upon which to do so.

Genetic selection at it's finest... Dogs which all have a distant common ancestor selectively bred for certain genetic traits, resulting in vast differences in appearance and ability.

I think there is a great case for seed vigor without genetic rifts being in the equation.

The plant has an annual life cycle and as such uses this process to shed disease and pest infections

that said I hate to be captain obvious (no dig at anyone) but epigenetic effects on a plant, regardless of capacity to pass on such effect, are temporary

that is, like a disease or a pest infection, epigenetic effects are reversible

what people are avoiding is the big picture, our own personal culpability as a community at large

the marijuana trade is blowing up and in its quasi legal for in California we are seeing a huge amount of sharing trading and unmonitored agricultural commerce that could be doing more harm that good by unknowingly transmitting disease and pests

the mass of inexperienced aspiring horticulturalists are compromising a plant's health, exposing it to many many gross environmental variables and then trading their stock and letting it mingle other gardens

there are so many great reasons to run from seed

i do believe however most cannabis has a remarkable capacity to rebound from almost any health calamity also, thats been my observational experience
