24 hour dark period before harvest

Keep in mind that this has not been disproved either!!!!

[QUOTE=Rusty Trichome;1955561 I'm very doubtful about the assumption that a cannabis plants response to darkness is to increase trichome production. Increased trichome production has nothing to do with darkness, or lack of light. [/QUOTE]

University of Mississippi (where your govt. grows pot) studies recommend harvesting marijuana plants at night....before dawn to be exact for increased potency.

This leads me to believe that an increased dark period or any dark period will increase levels of resin.

I tend to believe the scientists at University of Mississippi. I have read about this technique in many "experts" books. Surely authors of millions selling grow guides can't be wrong.

well the reasoning behind that is (from what I hear) is that the nutrients are in the roots at night and so harvesting at night does not increase potency but rather makes for a smoother smoke that tastes better

So, harvesting before dawn has now morphed into days of darkness? Even if I were to believe you...I'd want proof of your insight, and to view the findings myself. Facts seem secondary to you "proving" your points, as you never seem able to provide them.
I would most certainly love to see this study by U. Mississippi. A copy of the summary, or the link to the report in it's entirety would suffice. Since you seem too have the report, or have at least seen it yourself...by which mechanism within the plant biology does the trichome production increase as a method of self-preservation due to extended dark periods? If anything, this is the only lunar phase I'd be willing to believe in. Just because I have more sleep in my eyes in the morming, doesn't mean I make more during the night...just means it has accumulated and not evaporated, not been wiped away, is not retracting from sunlight or blown by the wind...

Yes, I can see where your insight is soooo keen.

Again...you fail to provide proof, and your hypothesis is flawed.
So because someone publishes a book touting the existence of martians, you would, simply by the context of "they can't be wrong", determine it true simply by the sheer volume of books on the subject? And that their motives were of genuine belief, not for financial gain...? Or that horoscopes are guides to wend our way through life, as the stars have ordained?
lol. Too funny.

I am one of the University of Mississippi scientists. Working on my Masters right now, so I took this job for the free tuition. Yes, we did make G-13.

have you done double blind studies confirming this data?

if so can you give the level of THC with the dark period and without?

go ahead and throw in the statistical mumbo jumbo
(I just took an applied stats course and I would love to try to decipher it for everyone else)

Ok scientist aside (congrats btw) how MUCH of an improvement are we talking? Seriously, enough to make a difference? There's so MUCH crap out there.....C02 fizzies, 3 days of darkness, a nail through the stem. How MUCH does getting up in the middle of the night to harvest help your grow? Enough to do it or something merely recordable on a graph or something?

with the scientists at work

they could potentially tell us whether there is a significant difference (or whether the differences could be explained by chance*depending on the sample size) and how big of an effect is by computing additional formulas

[Weedhound]

I don't know anything about computing formulas.....we're talking about a plant, not an inert object Revanche.

But I sure am not getting up at 3 to harvest my plant to get one less hit off the joint to get high.

If it's REALLY significant I'll try it. But I have a feeling if it WERE really significant we'd have heard about it by now.

One thing about cannabis growers.......they tend NOT to follow the mold..... which is both good and bad. (But in growing.....usually bad )

[stinkyattic]

Without lab testing equipment, you are not going to be able to discern ANY difference in effect from plants harvested in the morning or at night. The difference is too subtle and slight.
A couple days of pure dark will definitely kick-start flowering, and is the trick to finishing a long-flowering strain in a short-summer area. 4 days darkness, then put out August 1st for a mid-October harvest before frost.
When to CHOP is totally up to the grower. IT doesn't hurt either way so it's a matter of preference. If you are going to do anything special to your finishing plants, flush them instead. THAT will give a marked improvement in product quality.
