You're a true blessing to the community WS. Bugs are what I've been told vectored this too. I haven't seen this problem yet..but am listening and being careful with all in-coming cuts as if they could be infected.I'm 100% convinced that we are dealing with a virus. Two of the most widespread and common pests in our industry (rice root aphids and western flower thrips) are both vectors for hundreds of different species of virus that affect thousands of different species of plants...and many of those viruses have only been discovered in the last 5-10 years.
There are many crops in agriculture that deal with similar problems as this, however there are protocols in place to make sure pest and crop cross-contamination are kept to a minimum, and when outbreaks occur it is a national concern.
Unfortunately, the cannabis industry has no regulation whatsoever, and in my experience 4/5 growers are dealing with at least one pest that is a known viral vector, and I haven't spoken to/witnessed a single grower that doesn't source clones from unknown sources (just because you know who popped the seed doesn't mean you know the story of the cutting, or of the parent plants). The lack of cohesion when it comes to pest awareness and the practice of breeding plants in synthetic environments apart from any natural process, on top of the clandestine and untracked nature of sharing/spreading cuts, puts cannabis at the top of the list for crops at risk for a viral collapse.
Almost every crop that is propagated through cuttings or tissue culture is contaminated by viruses, and every crop has dedicated research centers (either independed or university based) to stay ahead of the viruses and produce clean/resistant stock. As we speak potatoes and bananas are being decimated by viruses; berries, melons, grapes, squashes, and a countless number of perennials are also dealing with almost identical problems as us.
There are very few answers to this solution. I and others (@Ricksauce you're the man) are working very hard on trying to get professional eyes on this epidemic, it's been a hell of a year but I think things are finally starting to get moving.
I also firmly believe that unless someone gets a positive TMV result (so far IIRC no one has) that we have to stop limiting our thinking to just that one virus.
Thanks for all the great info @Ricksauce . I recently had my first dud experience from a GG#4 that I got from Harborside. I could feel something wasn't right with her as the fans were super small and it wanted to bush out instead of grow vertically, so I took a few cuts and just ran one as a tester before taking a whole tray and filling up a room. Sure as hell glad I did because in the end the plant wound up utterly worthless. I just hope to hell I didn't spread whatever it had to any of my other plants.
I think you might be the same person a friend of mine in Humboldt told me about, as she mentioned that someone came and gave a lecture to her group about duds and how it may all be tied into an unknown virus. Anyway, thanks again for keeping people informed and I look forward to seeing what the results are on what is causing this.
We have a half dozen positives for TMV in cannabis, immuno-assays. Fairly unreliable imo. They're for toba genus. We also have maybe 25 solid duds cases testing negative by the same method.
Lots of work ongoing on this now. It's all serology and PCR based. It'll be a long study. We'll publish when there's something conclusive. Until then, grow good plants. Meaning: grow the best plants and throw shitty ones away. And grow the best plants you have, well.
Old moms are more likely to deliver dud clones. Cloning off your previous generation (assuming non-duds) is more successful than off of mother plants.
We've also successfully outgrown duds by cloning quickly off a dud, growing that outas fast as possible, cloning that, and repeat 3+ times. But given enough time, it usually duds again.
Milk, physan, whatever you like to clean with probably won't hurt. Who knows.
Just my opinion, take it or leave it.
Ya gg#4 hopped across the pond and now the duds will spread. It sucks I know from expirience. Keep it clean take strong cuts.this is a nasty one. It's visited the UK too.
from at least 2 ( and more likely 10 at least-)
different sources on diff continents.
The ones I know who had success used ogbiowar or essential oils. Others suffered almost bankrupting losses growing this evil ? Whatever it is.
bud is worthless, no resin, no smell or anything.
I would not take clones from anyone know.
I'm sure the breeder already knows:) sad they care more about fattening pockets now then working through the kinks and keeping customers.Viruses can be passed on through seed. I don't know if that's true of all viruses, but IIRC it is of tobamoviruses. I would definitely let the breeder know.
Yes, I got about two and a half ounces off that plant... all the buds were small and rock hard... No fluff... but I Schwazze.I have a critical kush that just dudded. About to toss it. These guys say duds dont grow flowers. Is your critical cut producing flowers yet ken dawg?
I actually had a lady in my room that looked alot like that gdp on the right last run, she was my larfiest plant and slowest all the way along, weakest branches as well. I thought i had done something early on but maybe i need to go back through some picsWell damn! I've got 2 that I've been watching - freaky as hell! Not cuttings though.
Ken's Grand Daddy Purple - breeder pack - got 2 like this out of 10 seeds. They grew like this from seed and were weird from the start. They've stopped vertical growth and are just getting thicker (brooming). Leaves seem to all be the same size (no large fans) and have a puckered look.
Growing 7 strains this year and this was only strain effected.
No signs of health problems (spotted lower leaves are due to K def from PH problems which is fixed - all new growth looks very green and healthy).
I really doubt just these 2 picked up a virus - I think it's genetic.
I know viruses can mess with genes so my gut says the mother plant had it and the genes of her seeds are altered.
If it was a virus ON the seeds, wouldn't it have spread to the other seeds in the pack?
Maybe I should contact them to let them know they got a problem goin on?
In any case, I won't be buying more of these seeds unless they can guarantee me that they've tested and dumped any effected plants from their breeding stock.
Both have been topped, planted in same batch of soil, treated identically. Dud drinks a lot less water.
Normal GDP on left - Dud(?) on the right.
