I've got to figure out how to plant this. I can legally only grow 6 plants in each flower tent.

Sheberghan – The Real Seed Company
Malawi Gold – The Real Seed Company
Iranian – The Real Seed Company
Balkhi – The Real Seed Company

No tracking on the other order yet.

I can run less than 6, but not 2 of each. Gonna have to choose what's first and if its compatible with anything else.

Probably 1 malawi in its own tent and 5 of the others in the other tent.

I'd definitely include the Balkhi in your next grow. Maybe 6 x Balkhi and 6 x Iranian or Sheberghan?

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.

Excellent! I knew I wasn't the only one working on this! I currently have three thcv Victory seeds and 10 Jack the Ripper's on the way as well as 10 Durban Poison seeds from the real landrace team. I'm just a blue collar worker though trying to help my wife's epilepsy and won't be able to afford testing on every plant but hopefully with the community's help I can produce something great!

Friendly reminder that these are unworked landrace strains, three of which include CBD-dominant phenotypes. I'm sure the Malawi is potent, but with this low of a plant count you may have to plant them for a long time to find a pheno with detectable THC, let alone THCV.

Yeow! Dude. You jump in with both feet. Excellent yourself. I'm sure we'll all be interested in the outcome of a Victory grow. Are the JtR seeds from the Subcool line, or elsewhere?

That was supposedly from a Syrian landrace, 7% THCV, took two years to find a high THCV phenotype.

Wait, are you saying 1 plant in a 4x8? And train the crap out of it to take the vertical growth and make it horizontal?

I'd really like to run multiple of each type just to improve chances of getting that outlier chemotype.

Maybe you can plant 4 -6 and clone them early and toss the big ones. Might have to do it a couple times before they get old enough to bud.

https://www.tltseeds.com/durban-poison-highland/ This is where I ordered mine, the website says out of stock but after emailing them I got a 10 pack. They said it was donated by a private collector.

Funny just how little consensus there is on what to do. Intelligent people with good experience disagree on even the little things like how much heat or humidity.

Maybe we can do some sort of poll as to what conditions to test, and I'll be the team's virtual lab: growing, testing, documenting, reporting and perhaps we can figure this out together? I would share 100% of the data and resulting genetics to whoever wants them.
[/QUOTE]
I'm very interested in working with you. I have acquired 3 feminized THC-Victory seeds from Dutch Passion, 10 Durban Poison Highland regular seeds from The Landrace Team, 5 Jack The Ripper regular seeds from CannaPot and 5 JTR regs from Chosen Seeds. I would also love to share my genetics with you and any results I may come up with unfortunately I am just a blue collar worker and cannot afford home testing equipment or to send out my samples for testing so I will be relying mostly on anecdotal evidence. My main goal right now is 2 reproduce more seeds of the THC victory given that they cost me $200 I initially set out on this breeding Journey to fulfill a long-time dream of mine it just so happens that my girlfriend is epileptic so I'm now combining my passion for growing and my desire to get her off of prescription medications. Or at least lessen the amount she has to take.

I circled the bait hard on the THC Victory but ultimately did not pull the trigger. If I had a confirmed report that it was not just marketing, I would have made the purchase. Perhaps it is you that will confirm the genetics are real?

I'm happy to test for you if we can figure out the logistics. I'm in St. Louis.

Your motivations are very similar to mine, I look forward to working with you!

I'll be honest - I have never done this type of grow before so I am trying hard to get it right in my mind. It's still unclear to me. Everything I have done to this point started with seeds, most of them feminized, and then clones off the plants that came out of those seeds. I have never gone back to the source like this and have never done breeding. I have a lot to learn here so any assistance is appreciated.

Malawi is a big plant. I have an 8' tent. The HID tent gives me a total of about 5' clear to grow in starting at the top of the pot. The LED tent I can add about 6 or 8 inches to that height. Still nowhere near what this plant wants, so I'm assuming I am going to bend them way over to make it work.

Some of these are going to be boys. They need to get culled. But they could also be the high THCV outlier too, and the pollen could be valuable. I have no idea how to save pollen or where I would do that. They would need to be grown out beyond where I would normally cull to sexual maturity. I don't want that happening in my lab.

Help me get my head around this...

Something looks amiss in that report.

How is the THCV decarbed (not THCVa) and THC and CBD are not? Based on my understanding of test procedures and mass spec, you either decarb the sample or you don't. You don't run one test decarbed to get the THCV value and another to get THCa and CBDa.

My bullshit detector is slightly dinging in the back of my brain.

Yeah, I'm playing the lottery a bit with what I am doing. But I can't exceed my legal limits so it is what it is. Perhaps some other growers out there could pitch in.

I would keep the spectrum leaning blue until the stretch is done (or you are well into flower) and you should be fine.

You're smart, you will figure it out.

Thats why i wrote supposedly...
But i do think middle eastern varieties, Syria, Iran, Irak, Lebanon, Turkey are very Interesting.
Maybe some of the last uncharted territory of cannabis genetics.

Im trying to grow a 15 foot tall colombian in a 6 foot closet. Plants are a month old grown 12-12 and show no sign of sex yet. My plan is establish clones and throw the mothers away. Then clone the clone and again throw the big ones away. Rinse and repeat until I have mature flower 3' tall or less. I have plenty of meds to hold me over in case of failure, so its all just for fun.

When I first started my search for the 'V' I had the same conundrum: Without any solid info re: which strains might have what I want and so many strains to try, it was challenging to figure out a path forward. I had a handful of seeds from several promising strains, but with only 2 grow areas so I finally chose to concentrate on 1 strain at a time. First one was Durban Poison (Dutch Passion) and it was a bust for THCV, but I have a jar of fems seeds if anyone wants to try some. Second was Malawi, and it was disappointing; it has some chops but not THCV that I could discern. Not coincidentally, I also have a jar of Malawi x Durban fems. I'm currently focused on Wild Thailand. The V is definitely there -- it's a very buzzy high and I've noticed a slight decrease in appetite -- so I plan to include one in my next grow as well, but still looking for that exceptional strain.

You have significantly more space than I, so I don't see why you can't run 2 strains in parallel, and still have 6 plants of each for chemotype variety.

You are a bit ahead of me I think but I see where you are going. For me it is not worth it to go thru all that unless they are special. Once that special plant(s) is found, this seems like a good approach to normalizing down to proper indoor grow sizes.
