7 days of dark. The final flush.

The dark cycle is when cannibidolic acid (spelling?) is converted to THC bro, it's a proven scientific fact

I've read otherwise, but not from a reputable source.
Could you provide a link?

Dude come on, the rest of us had to research it, is Googling "does THC protect from UV" that hard?
Its been proven that cannabis grown at higher levels(where UV is higher) have more trics than plants grown under standard lights...it all makes perfect sense man, just think about it.

Why do people supplement UVB bulbs to increase resin production?

" it's a proven scientific fact". Source from christian scientologists. They are very smart.

Never seen outdoor grows putting plants in the dark on harvest. They must not have any christian scientologist working for them. I will put the word out.

If your going to claim it is a "proven scientific fact" than please provide the link.

I could be stuck sifting through threads just like this for hours doing google searches.

Often articles relating to cannabis provide zero evidence for the claims they make. Providing us(not just me) with a scholarly article will do alot for this thread, instead of just filling it with possible truths. I'm too scientifically minded to take "proven scientific fact" as real evidence.

Also I think your confusing two separate concepts here-

"The dark cycle is when cannibidolic acid (spelling?) is converted to THC bro, it's a proven scientific fact "

We were talking about whether THC can be synthesized in the absence of light.

We were not discussing this-

"does THC protect from UV" that hard?"

That is another question that I have an interest in, but they are two distictly separate inquiries

Also this-

"Why do people supplement UVB bulbs to increase resin production? "

I'm sure most people supplementing UVB light do not fully understand why they are doing it. And just because they are, does not prove anything

What I have read(and it was not a reputable source which is why I am interested in finding one), is that UVB light is needed to convert the precursers of THC, into active THC.

There is another thought that UVB light stresses the plant in such a way as to create a response in the plant to produce more THC.

Those are two distinctly unique posibilities for an answer to your last question. And the implications are huge.
If UVB does not in fact trigger more THC production but rather merely converts precursers into THC, then using UVB througout the entire bloom is unnesseccary and possibly detrimental to the total levels of THC(because THC is also broken down under UVB light).
If this is the case it would be best to wait until the very end of the cycle just before harvest allowing THC precursurs to accumulate in the trichromes(and thus not be broken down from THC, as they will have yet to be transformed into THC) before illuminating the plants with a significant dose of UVB, immediately prior to harvest.

That is why I am interested.

The extra dark time also starves the plant and forces it to use up any stored sugars and carbs it can to keep itself alive.
So not only will you get more resin(not going to join this debate) but you'll have a smoother smoke

I've read that light is needed to convert THC precursers to THC. Does anyone have any good links regarding this? If that is the case the 72 hours dark may swell the trichs a bit, but unless more light is then given the precursers will not convert to THC

Why do you want the plant to use stored sugars? They play a key role in the curing and fermentation process after harvest. And those sugars are mainly stored in the fan leaves, which most remove at harvest day anyways. So why starve your plant to force it to use up something thats going to be removed anyways.....

I would love for just once that someone used this:


For those of you that don't know what it is...you need to re-visit grade 5 science.

The idea(and I'm not trying to claim this is true at all... just an idea), is that the buds would already be partially cured even before the plant is chopped and the drying process begins.

I agree, but if someone else has already done the experiments for us, then we don't need to do the tests ourselves

Actually there is no hermie as you incorrectly stated. Marijuana has a survival instinct that will, on occasion, allow a plant to make a seed or two without being pollinated. This happens in order to ensure the survival of the species in adverse natural conditions. If it was a hermie there would have been far more than 1 seed.

If you understand the life cycle of a MJ plant this makes perfect sense. Trichomes are simply a tool that the plant uses to catch pollen to reproduce. The later in the season the more the plant produces to try to reproduce before the season ends and the plant doesnt carry on its purpose. When you put the plants in darkness it sends a message to the plant that the season is coming to an end and thus it is losing its opportunity to reproduce. Thus it makes more sticky trichomes in an effort for a last ditch effort to catch pollen before it dies.

So in your world the trichomes collect pollen and plants seed themselves without pollen. Trichomes are (as previously stated) a natural defense to uv rays and also insects.

So trichomes are made by UV and not by the dark? All the different scientific claims are confusing me.

If what people are discussing, or arguing, in this thread would be on a 5th grade science level I would agree, but what is being discussed/argued is something that takes actual true scientific experimentation by highly educated people with doctorates and lots of high tech equipment all used in a highly controlled environment and using control groups.

This is not the sort of thing someone can prove in their basement or closet or storeroom or attic of garage or grow-tent etc.

And if you play semantics long enough a bit of true has its way of leaching out...also has a way a separating fact from fiction...

Why not?

what if I just happen to have a high performance liquid chromatograph with diode array detection in my grow tent?

hahah just kidding BT

On grow sites semantics are usually relied on to deny fact, proclaim it fiction and then used to validate opinion and personal belief that then replaces fact.

Nice dig...

The problem is it's still only scientific speculation regarding the exact function of resin/trichomes on marijuana. Particularly why the resin changes in the final days that would seem to serve little purpose to the plant. And it would apear that all those tiny crystal clear trichs would stop little UVB or sunlight, and may even act like micro-magnifying glasses on the plant's surface. And if the sunlight/UVB theory were correct the plant would likely produce more prominent trichs earlier on in the plant's development from seed. It doesn't seem to make sense that they're particularly more fragile or sensitive during the seed development stage that likely supports the idea of resin and trichs. Insects seems to be the only logical basis that may fit the question. But it's still only speculation. Resin, THC & Family, and the great mystery of why it get's us high.

They start to talking about cannabis around 55 minutes. The whole thing is very good, worth a watch.

you cant and dont flush organic soil... if your using true orgnaic soil then theres no need to flush, the only reason you ever flush your soil is if you use bottled nutes...

No it wouldn't because the SAM (shoot apical meristem) doesn't turn into floral meristem until it goes through the inflorescent meristem stage. That's why the trichs don't get produced until flowering. Notice how if you just shove a plant into flowering, after two weeks (the inflorescent stage) you'll see trichs.
