Kevin Jodrey & "Scrubbing" Clones of viruses

Hello,

I've been watching some videos on Kevin Jodrey. He has been mentioning cleaning/scrubbing clones of viruses/pathogens.

It is only mentioned very briefly. How is this done?

Would he be speaking of tissue culture?

This is the series:

Cleaning or scrubbing clones wouldn't be efficient for the production of virus and pathogen free plants. However, this could be performed with specific disinfection and treatment of plant material through tissue culture protocol.

A wide range of microorganisms (filamentous fungi, yeasts, bacteria, viruses and viroids) and micro-arthropods (mites and thrips) have been identified as contaminants in plant tissue cultures. Contaminant may be introduced with the explant, during manipulations in the laboratory or by micro-arthropod vectors. Contaminants may express themselves immediately or can remain latent for long periods of time. This often makes it difficult to identify the source of contamination. Disinfection protocols have now been developed for a wide range of plant species including those infected with viruses/viroids or endophytic bacteria. They may include the selection of pathogen-free donor plants or donor plant treatments such as thermotherapy. Also microbiological quality assurance systems (e.g. Hazard Analysis Critical Control Point; HACCP procedures) have been adapted to the needs of commercial plant tissue culture laboratories.

Yeah, he's partners in a new tissue culture lab that's producing clean clones from tissue and cleaning up old cuts that have lost their mojo.

I can't wait to score an SFV that's in good shape...

Yes, What a tool it would be for old clones. That was my thought.

I don't know if it was the same video, but he was talking about cleaning up cookiefams genetics, sherbinski was who he mentioned I think.

Perhaps the old story, "my cut has a virus, should I burn it?" Will be easy to answer soon.

Kevin's videos are an amazing resource. Ten years ago I visited his shop and he was really helpful and answered all my questions and his flower room was just amazing. I've never seen anything like it in person again. (Chaco's was close.)

They had the best prices in the state for flower at their dispensary too.
Very compassionate dude.

UV light has been used to hold off resistant virus's on tomato's. Not eradicate them, but keep them in check. I image some sort of work along them lines could kill a pathogen, and leave the plant.. capable of recovery.

I've seen old indoors clones/mothers put outdoors and seems to wake them up a bit in terms of vigor and size of growth. Not sure if it is just light intensity or virus/pathogen shift.

His hypothesis is that sub irrigation farming methods coupled with probiotic techniques can revitalize old tired clones. I believe now he has moved on to tissue culture though.

I don't know if that's true, I can't confirm it either way without some sort of controlled experiement, but I watched his old videos about this and bought myself 8 sub irrigated planter beds. They grow some of the healthiest plants I have ever grown with minimal attention or input. Even on some of the more harder to grow plants I keep, such as Giesel... She demands extra nitrogen, calcium, and magnesium levels when grown normally in pots, but when she's in a sub irrigated bed it's pretty much auto pilot til shes done. The plants never have a yellow leaf on them, and all the plant material is highly flexible "juvenile" material. No hard woodsy growth, ect.

I took in a cutting of Animal Cookies which had some dudding problems and after a few cycles in a SIP she grew like a different plant.

I did one little experiment over the summer with a sub irritated container and was amazed at the massive performance boost compared to watering the dirt from the top.
