Do I REALLY have to wait until morning to harvest?

I have been reading that I need to wait until morning to harvest. Apparently the THC content can be higher then as opposed to later in the day. Any truth to this?

as far as I can tell for harvest, you cut nnutes to water in the prior week, right before you chop it you can put the plant or plants into a 24hr-72hr dark period. that should "stress shock" them into putting out more trichs. then, instead of turning the lights back on to chop em, to cut them in the dark because the nute levels in the plants are less since theyre not taking anything up from the soil. i could be off a lil bit due to me compressing a few posts ive read, but i hope it helps ya out.

Gosh all the effort and money I put into keeping my plants at maximum health 1K hortilux co2 generator and controller when all I need to do is "stress shock' them in the end lol,thats a good one.Not trying to be a smartass man but I cant help it when I hear this kind of shit,kinda like improving potency with 48 hours dark..its bunk.You are going to reap what you have sown in 100 plus days,nothing is going to magically improve a fully ripened plant.I'd like to suggest full hydration hours before or the night before harvest,a hanging hydrated plant takes longer to dry resulting in a better cured smoke.No magic trick just common sense

If I remember correctly, the 48 hours of darkness at the end has been de-bunked... Someone in Holland several years back tested thc content with and without the totally dark days and found a slight drop after an extended dark cycle when compared to the plants given normal lighting.

exactly, or if you want to harvest in the morning they will dry a litle faster because they have let most of the water return the roots as opposed to having all up in the flowers and leaves

It seems to me that if you need to be concerned with doing something in the closing period of your grow to boost the THC content, then you did something wrong all along. I doubt there could be much difference. Just focus on growing healthy plants with a balanced diet. There are no magic tricks. The most potent, tasty kick-ass weed I have ever encountered is from an old hippie witch lady who grows in garden compost, pro-mix and a handful of cheap lawn fertilizer. She could match any bud you find at the Cannabis Cup, and beat most of them.

You just described my dreamgirl,I'm an old hippy warlock grower.If she's Floridian I must have her.

I think i read the same thread where it says to cut them before sunrise because it will allow all the nutrients built up in the leaves from the day before to drain down into the roots at night. Therefore there will be less chlorophyll in the plant when you cut it. I think it just makes for a smoother smoke and helps in the curing process.

yup... this is big myth. The nutrients do not flow up into the leaves and back down into the roots.

The nutrients which are mobile in the plant (N, P, K, and MG) can be taken from one part of the plant and used by another plant, such as when a deficiency shows up in the lower leave because that element is being moved to the tips to support new growth. The immobile elements must be in constant supply to be available to a plant because they cannot move around with in the plant, that is why a deficiency in these elements always shows up in the new growth first.

The chlorophyl in the plant breaks down as the plant dreis and cures. you can see it happening as the plant material goes from green to brown. Other than that the only way to limit chlorophyl is to stop feeding the plant well before harvest (two weeks at least). This allows the plants to stop taking in immobile elements and start exhausting the mobile nutrients it has stored.
The only nutrients and energy that goes down to the roots is for growing the roots. The roots are not 'storage tanks.'

The theoretical reason to harvest in the morning is this... light enables the plant to produce thc, but Light also destroys thc. During the light cycle the plant absorbs more energy than it can process, so it continues to process this stored energy during the dark hours until it is exhausted. The resins produced overnight, using that excess energy doesn't get used during daylight hours, don't get acted upon be light and thus have a slightly higher thc content vs cbd content than if the day's light had broken some of the thc down and elevated the cbds slightly.

With that being said, My theory for the reason that the extended dark period ened up resulting in less overall thc, is that the plant run's out of stored energy and can no longer continue to produce more. Basicly just sitting in the dark, not having it's 'batteries charged', so to speak...

So how does one know exactly how "charged" a plant is? Perhaps if you are harvesting a plant that has not been fed pure water the last 2 weeks it would have plenty of "stored up" energy sitting around for 48 hrs of dark to make a difference. Or maybe its the size of plant that matters, or the number of fan leaves, or size or mass of them, as fan leaves are known to be primary "storage" facilities for the plant.

The fact is you cant tell whats going on. there could be a whole other reason why it doesn't or does make sense and we are completely missing it. Until we know for 100% fact, anything you see here is just 100% opinion, theorized conjecture sitting on a table.
If you really think it makes a difference, then do it. Otherwise, don't. But dont run around telling other people to do this or that if you arn't 100% sure yourself to begin with.
speaking from pure common sense point of view, you dont normally see big changes in plants in just a 24 or 48 hour period, and if you do, its just the very very beginning of a change. On the other hand, environmental changes (such as a foliar feed) are known to make much more sudden changes. So dont rule out darkness as a variable for sudden changes if you dont know how it affects trichrome production and things of that nature either... you really cant win this argument whichever path you take haha. That is one problem with forums, you can ask a question that has no real answer and there is no end to the line of people waiting to answer it.

I'm not talking about storing up nutrients, I'm talking about energy which comes from light, which is all used up before a 12 hour night is finished, the chemical reactions and metabolic processes from the photosynthesis winding down. Nutrients stored in a plant generally take a couple of weeks to use up.

The fact is... just saying 'the fact is' before you make a statement doesn't give it any authority... In fact, you're simply wrong. I don't now why you have a problem with me sharing. The small portion that was actually opinion I said was my theory. The Fact is there were conclusive test done in holland showing NO measurable increase from an extended dark period, and in fact found a decrease.

I don't run around telling people anything I don't know. I remember when the data was published, wether or not I can find it now. If you really think it makes a difference, then do it by all means, but it won't change the way things work.

No one is trying to win any argument, I was simply pointing out what the only actual research ever done to test the theory came up with for results... I could care less what you believe... I'm trying to pass along things I've found out, not argue with your opinions,and am not going to argue any more about it...

I dont really think that there was an argument going on here. We were all just giving our two cents about the topic to maybe come to a conclusion to this hypothesis. Noone said anything was set in stone. This comment is aimed at you extinctx11.

Would you trust a conclusion on this particular subject from anyone here when at next harvest you can know yourself?I say bunk because it has been in my case with all strains I've grown.Other people may think its helping I dont know.Your pistils turn a tad but probably would have with 48 hours of light anyway.Don't be shy give it a try!
