A video on youtube. I already came across that while looking into this.

At least they had a slide showing some of the nurseries that they claim have tested positive so people can avoid those if they're concerned about this. I guess that's the most valuable part of the video.

You mean discussing the inoculation tests, how they came to causation, even their creation of a hypothesis and applying the scientific method through experimentation was not at all valuable?? Are you able to understand it at all??

I understand it.

I'm not disputing that they identified it. I don't agree that it's as serious as they're making it out to be. That's more of an infomercial for their Clean Plants Program than anything.

Looking forward to all the posts from some grower with a messed up plant asking if they have HPLVD. It will be like a flashback to the "Is this TMV?" era.

Don't know if this is useful.

Nah. Thats already happened. Those threads are several years old now. Commercial and hobby growers alike were just relieved to finally have some answers.

I have experienced it and lost a jackpot pheno of Kosher Kush to it. It wasn't from Dark Heart and I've never purchased a clone from DH or anyone.

@curious2garden
Stumbled across this thread this morning after seeing smallbud bickering about bK78 on a different thread. Not sure how I missed this thread over the last few days.

I have some questions about your experience with the Kosher Kush keeper dudding out because I am genuinely curious about it, not being a troll:
It sounds like you lost the Kosher Kush keeper before HLV testing was available, correct?
But you now believe that a HLV infection was likely this was the root cause of that one dudding out?
And that you think it may have come in through infected seed stock?
Have you had any of your plants more recently tested to see if any other plants in your grow are HLV positive?

I skimmed to catch up mostly and I’m sorry if the above have already been answered in this thread or elsewhere.

I’ve heard of plants dudding for over 25 years, so while I have never experienced it, I don’t doubt that it has been happening for a long time. Theories of dudding due to too many generations of clones being taken/genetic drift never seemed valid to me though. The more recent identification of HLV as at least one cause of dudding seems way more reasonable.

I know you didnt ask me but IMO, testing isnt enough. Its just a tool used in every sector of AG. What I've found is you really need to observe the plants thru several cycles. Its one of those things where if you run thru enough plants, you just know something is off. With testing, it allows growers to skip the steps of running through the gamut of normal trouble shooting.
I knew a couple of my plants were positive before I even sent them off for testing. Infected plants have very distinct markers that are easily recognized if you have the right info and experience.
And there was a time when I would've kept and grown out mutants found from seed. Not any longer.

I'm still on my first cup of java so forgive me but I think the last part of your post refers to epigenetics?

Coming in with the seeds is a possibility although I ran an F2 table of clones and sent the seeds too many people. None of them have dudded off. So I'm not sure if seed stock was the source. But it is possible. Genetic drift doesn't happen in asexual (cloning) methods of reproduction. Although stress and other factors can act upon the epigenome to create clone degradation. One stressor can be disease.

I lost my KK before testing was available.
I think it's possible it came via seed stock but unlikely.
No I have not seen any signs of dudding off after I burnt down that grow. I destroyed all my genetics and waited several months and cleaning cycles before starting new genetics.
I have not tested as all my plants since then have grown normally or what I consider within normal parameters.

I hope that helps and I don't see you as a troll. Feel free to ask away and even disagree with me. I'm fine with that. Essentially we are at the start of the science behind Cannabis, fifty years from now it will likely be a new world.

No, not referring to epigenetics at least not in the sense that curious2garden elegantly framed it in post #354 as a route of clone degradation from stressors. I was referring to the bro-science theory of “genetic drift” causing dudding of a line that goes something like:

“Dude, if you keep taking a clone from a clone, like, eventually its genes will, like you know, change and the plant will, like, get all weak and lose its vigor and, like, its potency and shit. The genes, like, you know, drift away from the original genetics and shit.”

Totally agree that we are at the start of an era that will see a huge influx in true science
regarding cannabis.

FYI, I pointed out that I was not trolling because HpLVd is a worthy topic but some of this thread got a little catty.

Also, @Auntie Janes Nursery, I saw a flying cannabis car one time, but it involved mushrooms, so that probably doesn’t count.

Yeah I was at the front of the derailment train. I don't do well with any type of theft. Theft of intellectual property seems to get a pass too often. I often wondered if it was because it wasn't a tangible item. Anyway the OP needed to get DH's permission or use a fair use quote and link to the articles, not just point vaguely in DH's direction. Then when he doubled down I entrenched. It's always best when you fuck up to clean up and move right along with a good topic. Oh well.

interesting how some of the same people dismissing this research because Dark Heart was involved are some of the same people that cite research put out by a nutrient company that claims feeding up until the last day of harvest makes the best tasting weed. The irony.

Here's the best article I've found that references HpLVd as well as other forms of CDS "Cannabis disease syndrome". There are other viruses that affect cannabis that were identified long before this HpLVd.


And how come nobody is worried about "Lettuce Chlorosis Virus Disease: A New Threat to Cannabis Production"

Here's an actual study:


There are many pathogens that are a threat to cannabis. HpLVd is just one of many but one that apparently has been monetized.

Other pathogens and pests are more of a threat than HpLVd. This screams of a way to profit and nothing more. Hype it up and have a never ending stream of revenue from testing for something that is no more of a threat than other pathogens.

Many labs provide a broad panel of tests. It isnt just HpLVd.

This is no different than any other AG testing. The only difference being availability due the legal aspect. That will change and soon we'll be able to send off samples to our local Universities. We follow the same procedures and forms when testing our berries.

Labs dont operate for free and we shouldnt expect them too

Because some people are "right" fighters. I'm guilty of it too sometimes but at the end of the day, I'd rather be educated about a subject than "right".
