Maybe @Aqua Man
@Moe.Red
Or some guru either of you could recommend can point me in the right direction.

The high THCV strains listed on the interwebs are non existent. Are there any easily accessible regular seeds I could get my hands on that anyone knows of?

I'm starting this discussion to help further mine and others knowledge of THCV rich cannabis strains.
I know that sativa landrace strains especially those that were native to Hawaii were THCV rich. There's a new one called thc victory, but what are some lesser known high THCV strains?
Durban poison, jack the ripper are a few but I want some seeds to acquire for breeding of my own high THCV strains.
Let the discussion begin.

Trips, if I had the genetics figured out I would share with anyone who asked. I'm still working it.

If anyone is reading this and doesn't know what THCV is, it is pretty amazing stuff. There have been studies, but not enough. To my knowledge it has not been synthesized yet like THC=Merinol. For someone with diabetes there seems to be quite a bit of promise. Just an all around interesting cannabinoid that has not been fully expressed and understood yet.

I am about to harvest 2 Jack the Rippers. I'm TLC testing weekly on those, and to this point they show no more THVC than a standard variety whatever. I'm looking hard at 3 things. I am either:

testing wrong
growing wrong
or
the genetics really are not what they are sold as.

I have the ability to control every environmental aspect (light, spectrum, temp, RH, res temp, CO2, PH, etc. etc) so if someone has an idea on what set points to change to maximize THVC, I'm all ears.

As far as the testing, I am using standard TLC tech and I have done enough of this that I get consistent results. I think the biggest factor in expressing THCV is the decarb prior to TLC testing. I think THCV needs longer and hotter than THC to move it from acid to a nice spot on the plate, which will diminish the THC and CBD components, but I'm fine with that if it works. Still testing that theory out.

As far as the genetics, I have done Durban Poison and Jack the Ripper. I would be willing to pay the exorbitant price for THC Victory if I knew it was legit. Bottom line, I don't have the answer yet. But I am fully engaged in finding it and sharing with anyone when I do. I am open to ideas.

I have a bit of a lab in my basement. I think I may be a little unique there. If anyone has ideas but does not have a lab to try them in, I'll be your daisy, just gotta be a repeatable test using the scientific method is my only requirement. If it is not repeatable by another party, it is not data.

Yes, I think you might be referring to boiling point, which you don't want to come anywhere near when performing
decarboxylation.

I will be doing a series of tests at different temps and times on the same plant to figure out the sweet spot. I'll post results.

Question: When performing a decarb on live plant, do you think the lack of drying / curing could be the problem? What I do for these 2 plants is cut off a bud, and put it in my vacuum oven (wet) at X temp for X time under vacuum. The oven is PID controlled, so it maintains temp very accurately. I then process the result using TLC. I get good, repeatable plates. There is essentially no water left in the plant after the oven. I could also freeze dry, but that takes 24 hours.

My question really gets to how and when THCV is synthesized. My testing indicates it is not early in the plant's life. So when? Throughout the grow like THCA, ramping up at the end of flower? Maybe only at the very end of flower? Only happens when you cure? Man, if someone could clue me in here, I'd be off to the races.

I'll throw this out there -

I have 2 out of 6 plants that are about 20% amber trichomes that are supposedly high THCV.

Are there any last minute things I should try prior to harvest? I can change virtually anything. And I will have 4 other plants we can use as controls.
