Does Cannabinoid Production Stop as Soon as the Plant is Harvested ?

[St. Phatty]

I was wondering if the Cannabis plant cells stay alive after the plant is cut, while there is still water in it.

Basically I was wondering,if the plant continues manufacturing resin after the cut, for example taking all the last bits of its energy and converting it into Cannabis plant sap in the form of THC resin etc. ?

I know the terpenoid profile changes throughout the grow and cure!
I would assume it would have an effect on the cannabinoid profile also.
Just a guess!

Good Question. I'd have to say no because you used the word production. No, no additional cannabinoids are produced when you cut the plant down but the cannabinoid profile already present in the trichomes will change with time.

I do know that water stress can result in increased trichome density; a technique I employed many years ago. Several studies support this conclusion; google: "water stress" trichome.

Of course if you want to go nuts, add the term "defoliation" to the search string.

Googled it, but that just poses more questions on practical use:

Are you saying you no longer use the technique?
When and how severe a deficit to see a benefit? Did potency increase as well? Did it hurt yield?

thanks..

Hypo, I experiment with "water deficit" after flower and trichs are formed/developed (don't want too fuck up the development stage). Not all strains respond exactly the same, but the common thing I noticed are: the aroma (stink) is stronger and with more depth, the trichs/stalks seem fuller (I lack expert equipment to say definitively), and the buds bulk up a wee bit at harvest (probably the plant sucks up extra water after the deficit and seems to hold it). Too much water deficit (or at the wrong time) can result in the occasional larfy bud (as in Air Jordon)...something that is not common in my garden--as my buds are hard enuf to bounce off of walls, lol.

BTW, when I say "water deficit", I mean "soil dry"--but not to the point of plant wilt; not trying to kill the plant--just making it think that "water is no mas"...which should encourage the plant to initiate some of it's "natural defenses" of survival.

Play around is all I can say...it is a trick that I do employ and my flowers are strong in aroma, flavor, and potency--and do not "taste like everyone elses"....(lol, something I hear all the time).

I believe I have seen this in action.
EclipseFour20 have you ever noticed larger calyx size and more of them and less leafy growth during early flower around week 4.

I think I missed a watering and it happened, I think it was the cause.
I will try to post a pic.
I Just want to know if you saw a similar effect during drought testing!
Thanks

I don't recall seeing that--but it could have happened and I did not notice it. The less leafy growth makes sense--as the plant obtained what it needed from existing leafs (sink-source thing) causing the leaf to be momentarily "deficient", thus less leafy growth (no soup for you).

I did learn some stupid lessons that--had I sat and smoked a fatty and contemplated a bit, I could have saved myself some $$$ and a lot of work...like during those certain critical growth stages, forget about water deficits--give plants all the fertility and water they want. IMHO, save the water deficits games for the periods AFTER those critical growth stages--which is a good time to mess around/alter the plant's behavior (SAR, water deficits, etc).

Dam good advice right there!
My yield has suffered dramatically from not tending to the needs in these critical times.

Thank you

BTW the idea of "water deficits" came from research I did on wine; why is that wine produced from the same grapes, same vineyard, same cultivator, same winemaker can change year to year? Some years the wine is super exceptional (100 pointer) and others so so (pittui)...why?

One of the answers I found involved a concept called "terroir", defined as an interactive ecosystem, in a given place, including climate, soil, and the vine (rootstock and cultivar).

I came across a study that concluded:
"The effects of climate, soil, and cultivar were found to be highly significant with regard to vine behavior
and berry composition (an example being anthocyanin concentration). The impacts of climate and soil were greater
than that of cultivar. Many of the variables correlated with the intensity of vine water stress. It is likely that the
effects of climate and soil on fruit quality are mediated through their influence on vine water status."

The years which were exceptional vintages were years that had "water deficits"...hmmm.

IME, yes they do for about a week, but I do things way different than most. A lot of growers put plants in the dark after the chop, some up to 3 days before the chop. I water with boiling water, which kills the roots and deprives the plant of O2, I leave em under the lights for several days afterwards and they grow foxtails so yeppers they keep doing stuff by eating the leaves. Takes about a week for em to drop to death and 2 months to vine ripen, I call it brown bushin em cause they turn brown, the smoke is incredible but most growers won't take the time to wait for it

Ive had a harvest accidentally dry under the lights, thanks to a roommate that was watching my grow while I was on vacation. I thought it would be ruined but it was surprisingly sticky and tricromed out. In this instance I'd say the plants continued to produce oils after or near death.

Wow interesting

 

[bastar]

i think the production stop but if the bud see the ligh of sun the thc is degraded and lost potent no ?

No

Riddleme.....could you've please point me in the right direction to so some sources so I could better understand what processes you are using.. as I'm not knocking your info... actually very intriguing

I have also went out of town for a weekend and a deadhead og girl that was finishing up ran out of water and the top browned up quite a bit and was killer smoke.... but also I'm sure as with everything there are plenty of variables...

Not sure what sources you mean, years ago I wrote a ditty called the truth about flushing. I have been told some of the links in are dead. I posted it at Jorges forum here ,,,

http://www.marijuanagrowing.com/showthread.php?6147-And-Now-For-Something-Completely-Different

and talk about what I do now based on several experiments, it's all based in science.

as for them degrading in the light, I did a test recently on two buds one fresh and one left out in the air and light for a month on my coffee table, the fresh one tested 25% THC no CBN and the month old one tested 22% thc and 1% CBN. Yes it degrades but not as fast as most think

 

[blastfrompast]

I have let OD plants in pots dry on the stock OD before...

Smoke was great...major foxtailing, lots of amber trich's tho and it really gave me that SLEEPY weed hangover feeling where you just want to go to sleep....you know the feeling that only goes away with a fresh hoot..

I still have a couple oz of the larf left...3yrs old in the bag, roll a spliffy and it still gets u messed up... It has made some really interesting BHO over the years also...

I will have a small dab before bed if I am having trouble sleeping due to my neck.

BEWARE THO....I tried it this year again....and waited too long....FROST... Turned my one surviving Self'd WW bean dark dark brown...

I have yet to be brave enough to smoke a bit..lol....and with my Indoor..why would I want to..lol
