On the subject of what causes the "energetic" feeling of sativas vs. indicas...
One should be able to see a one-to-one correspondence between specific terpene percentages, combined with specific cannabinoid percentages – distinct for sativa vs. indica. Does anyone know of a study where this has been investigated and results shown?
Here's from an article on the subject:
"Examples of popular sativa strains include acapulco gold, panama red, and durban poison. Users can get an understanding of expected effects by knowing the THC and CBD percentage, understanding the terpenes, and by reading reviews. Strain guides will combine user reviews to create easily understandable
guidelines.
For example, acapulco gold is noted to be peppery, with the top reported feeling as “happy”, and “energetic” coming in fifth. Durban poison on the other hand has “energetic” listed as it’s number one reported feeling, with strong fruity flavors. This shows that not all sativas provide the same effects, smells, or tastes."
So, they are saying that Durban Poison is ranked high for an energetic effect, while Acapulco Gold's energetic effect is not so pronounced.
Cannigma.com says, "Based on user reports,
Durban Poison tends to be energizing and uplifting (probably thanks to the THC-terpinolene combo that is thought to be affiliated with sativa-like effects)...".
It could be that pure sativas are always terpinolene dominant – I've seen a few examples, but haven't completely verified this.
Durban Poison is a 100% sativa, THC avg. 17-21%, 0.6% CBD, 0.8% CBG, with dominant terpenes
terpinolene, ocimene, myrcene, and caryophyllene.
Acapulco Gold is 80% sativa, THC avg. 14-19%, <0.2% CBD, <0.2% CBG, with dominant terpenes
limonene, pinene, caryophyllene. (Hard to pin down the terps on this one... another source says myrcene, limonene, caryophyllene – in that order. Other sources say terpinolene is the dominant terpene; however, it seems more of the sources show limonene is dominant.)
It's interesting to note that my best bud rot resistant plant now is HI-BISCUS, which is a 50/50 hybrid with sativa effects. THC is around 20%, CBD around 0.5%, CBG 1%. Dominant terpenes are
terpinolene, myrcene, and pinene. It has high resin production and heavy odor at harvest time.
Lastly, let's take a look at Northern Lights... 90-95% indica, THC avg. 22%, <0.2% CBD, 1% CBG, with dominant terpenes
caryophyllene (0.35%),
humulene (0.34%), limonene (0.25%), and terpinolene (0.25%). [Cannabinoid and terp numbers from Cannigma.com]
So, Northern Lights, according to this one source, can have a unique terpene profile where four terpenes are all about the same percentage. The strain is well known for having a classic relaxing indica high – definitely not energizing.
Cannigma.com says, "Caryophyllene and humulene are thought to be sedative, limonene is considered to be energizing, and terpinolene has shown sedative properties on mice, but subjective user reports on marijuana varieties high in terpinolene suggested an energizing uplifting experience."
high levels of myrcene (or already known to have high mold-resistance)
once I have ordered the beans, received the beans, germinated them, and get some weedlings... a lot has to happen... you know how it is! I'm gonna order them probably in 3 batches, starting with 3 strains from True North.
