just finished the final version of my post above ... whew!

Thanks! I just read Sensi's article on Jack Herer, talking about phenos A, B, C, D. Very interesting... A, C, D have sativa traits and B has indica traits. I read that B has the highest yield, although D produces "truly spectacular amounts of resin".You should be able to find some on that list that you like. I know that I like a bunch of them. I've only grown Jack Herer and Durban. Both were from Sensi. Neither had fungus problems.
It's funny that the Jack Herer I grew was one of those times that I tried growing more than one strain in the tray at a time. The other strain was OG Kush. It was before I had any control over the RH and relied on exhaust and fans.
I got bud rot on the OG Kush (huge buds) and no rot on the Jack Herer in the same tray. The buds weren't as big on the Jack though.
My Jack Herer was pheno C, the haze dominant pheno.
Where are you finding the terp numbers? I have a list of the ones in my main strain from the breeder but it's just a list of them, no numbers.Here's an interesting contrast...
3 Terp profiles for Jack Herer
(Jack Herer has 4 phenos A, B, C, D. Phenos A, C, D have sativa traits, and B has indica traits.)
2.57% total terps, terpinolene dominant w/ myrcene & pinene
My guess: mostly sativa traits, possibly pheno D
1.75% total terps, pinene dominant w/ myrcene
My guess: both sativa & indica traits, possibly pheno A or C
1.64% total terps, myrcene dominant w/ caryophyllene and bisabolol
My guess: indica traits, possibly pheno B
Compare the HSC's Humboldt Dream which is indica and shows quite a bit of bud rot resistance:
Let's say 18.5 mg/g total terpenes, or 1.85% total terpenes by weight.
Here's the terp profile for Humboldt Dream in the same notation as the above profiles for Jack Herer...
beta-myrcene.......... 0.91%
alpha-pinene.......... 0.52%
gamma-limonene........ 0.19%
beta-caryophyllene.... 0.12%
That's an insane amount of myrcene... reminds me of the terpinolene dominant JH profile above. Also very high pinene. I would say Humboldt Dream has mostly indica traits.
I have a Humboldt Dream in the flower house right now, and she's starting to produce flowers. She's looking very healthy, and showing some major leaf mold resistance, as compared to the Blueberry next to her, and a Grape Ape that I just harvested today. Perhaps the high myrcene and limonene are factoring into the leaf mold resistance. (By leaf mold I mean leaf spot mold, i.e. septoria and downy mildew.)
MCRLabs, public reportsWhere are you finding the terp numbers? I have a list of the ones in my main strain from the breeder but it's just a list of them, no numbers.
My question is more about seed lines for specific strains that are sold and labelled as "indica dominant" or "sativa dominant" or for example, 80% sativa/20% indica, etc.The only landrace I've grown so far is Hindu Kush.
It's an indica. It really hit me more like a balanced hybrid that made it easy to fall asleep.
I have also had a proprietary landrace sativa, and it had pretty similar effects, although I can't tell you where it came from initially.
I think most of the strains we have now have been bred with a preconceived end goal in mind. Plants that had effects that didn't fit into the goal were removed from that breeding project.
If you're looking for a sedative strain, and growing a plant that's labelled "indica" and it doesn't give you couchlock, or make you sleepy, are you going to grow it again?
Well, for some of them I would agree.My question is more about seed lines for specific strains that are sold and labelled as "indica dominant" or "sativa dominant" or for example, 80% sativa/20% indica, etc.
I'm guessing that any well-known hybrid stains like this will produce both indica and sativa phenos. And by that I mean, indica effects and/or growth traits, or sativa effects and/or growth traits. There are certainly many example of such strains, like Chemdawg or Jack Herer, that produce multiple known phenos.
Thanks for that.Hmm.
You got me interested in this. I found a site called greenhealthdocs.com.
They had a list of high terpinolene strains that was pretty similar to yours, although they didn't give the amounts.
One thing I found interesting was what they said about the effects of terpinolene.
Here's a bit of it:
Terpinolene when combined with CBD can provide a calming and relaxing experience, reducing stress and anxiety because of its sedative qualities. Terpinolene when isolated has natural sedative qualities. It’s one of the main terpenes in tea tree oil and patchouli and has been found to aid in relaxation.
Terpinolene + THC create a lively and energetic effect, driving creativity and excitement
Terpinolene + CBD can provide a calming and relaxing experience, reducing stress and anxiety
Terpinolene is also known as delta-terpinene and is thought to have both sedative and euphoric, uplifting effects, depending on the other terpenes and [cannabinoids] it is combined with.
For a long while, research scientists believed terpinolene to act as a sedative. This was due to experiments that determined mice inoculated with terpinolene showed a great reduction in muscle motility contributing to sedation. However, these findings contradicted anecdotal evidence of cannabis consumers who reported that varieties high in terpinolene caused stimulation. Upon further investigation, it was found that terpinolene’s ability to sedate may in fact be reversed when combined with THC. Therefore, research scientists believe that while terpinolene may act as a sedative in isolated form, it most likely acts as a stimulant when in the presence of THC.
It was sedative in mice at 0.1 mg, reducing motor activity to 67.8% (Ito & Ito, 2013), whereas subjective reports in humans suggest greater stimulation in terpinolene-rich cannabis chemovars (data on file, Napro Research 2016), possibly attributable to [acetylcholinesterase] inhibition effects in the presence of THC, a pharmacological effect measured with IC50 at 156.4 μg/mL (Bonesi et al., 2010). [ source ]
The dose-dependent inhibitory activity of terpinolene and β-phellandrene against AChE is reported in Figure 2. β-Phellandrene showed a selective activity against AChE, with an IC50 value of 120.2 µg/mL, while terpinolene inhibited both AChE and BChE enzymes with IC50 values of 156.4 µg/mL and 147.1 µg/mL, respectively. Except β-phellandrene, all tested terpenes showed BChE inhibitory activity (Table 2, Figure 3), with IC50 values ranging from 78.6 µg/mL to 168.7 µg/mL for trans-caryophyllene and linalyl acetate, respectively. Perusal of the literature revealed a promising agreement between our results and the reported activities of a number of terpenes. Indeed, an impressive body of information exists on the anti-cholinesterase activity of plant terpenes, and in particular of monoterpenes. Many works have concentrated on the action of compounds identified in Pinus essential oils and on the synergistic effect of a mixture of some terpenes. Perry et al.[16] reported the AChE inhibitory activity of α-pinene with an IC50 of 0.63 mM. The AChE inhibitory property was also reported for several monoterpene hydrocarbons such as α-terpinene and limonene[21].
Yes, it appears that THC (and other cannabinoids) combined with terpinolene and pinene produces the stimulant effect. They are all AChE inhibitors, including CBD; however some are a lot stronger that others. [ source ] E.g. "CBC and CBN showed weak inhibitory activities".Differing effects based on which cannabinoid it's paired with.
I think I also read that tetpinolene doesn’t seem to be naturally occurring in CBD strains?
One note on Durban Poison though, as an African landrace it can have higher than average levels of THCV, which is absolutely a stimulant.
That's an insane amount of myrcene... reminds me of the terpinolene dominant [Jack Herer] profile above. Also very high pinene. I would say Humboldt Dream has mostly indica traits.
