Difference between Sativa and Indica, Chemically?

Why is that Sativa's are more of an upper, and Indica's better for knockout? They both contain THC and other cannibinoids, but what sets them apart? Why do they flower differently (other than original location)? I understand the difference between them, but what I do not understand is the science behind it. I would really appreciate a good answer as to why the highs are different.
Thanks!

well how they plant grows and how the plant looks is its phenotype . the plants genetic make up like sativa or indica is its genotype. google it it will make sense

I am well aware of pheno and geno, but WHAT is the difference between the genotypes?

Different levels of thc/cann. in strains, Sativas take longer to ripen. thc more head high, cann. more couchlock.

I was reading your question again and im curious too. my answer doesnt really answer shit. ima look into it

there we go sounds like that might be on the right track

That is what I was wondering, but which sativa or indica has the higher thc/cannabinoids

Depends on strain and how You grow it! It is not a science as more an art.
Too many factors to say one is better than the other light, space, time, nutes etc,,....,.......

from my years of smoking dope i have come to realize that hybrids have the highest thc levels, also no pure indica or sativa is considered a medical strain. this leads me to the answer that selective breeding between the families of cannabis result in a better product.

See grow the 2 in question and see for yourself and then you can tell us which is better....lol.

i think the cbd content and all the other canibanoids (<-- typo im sure) including thc can vary chemicaly so they produce different effects but i could be very wrong. This is a great question thank you for asking and im exited to hear the other opinions.

you are correct dnk 7 long enough name?

cannabinoids, i think it is how its spelled.

Looks good, but does it really matter how it is spelled? cannnanancnaiiavbbiiniioi00ds j/k
just fn around.

Now that is science ! good one
and thc?

Is there any botanist that can make this horticulturist explain this? So far just a bunch of stoned responses

Hehe - im interested in this too. As written earlier in the thread the sativa matures pretty slow compared to indicas which could be the case of the trichomes too. This might make us harvest sativas whilst trichomes are still pretty milky and still not amber.
Another thing could be the production of CBD. Maybe indicas produce more CBD than sativas? - looking forward to getting the answer from a botanist ;O))

bump bump someone has to know
