flush/harvest question

^^^^This I know. I am asking what you mean by "not fully developed" because in most pics I cant see actual trich heads. Even in person I cant see the trich heads unless they are magnified. In your picture of the GSC I cant see heads. But it was used as a reference for developed trichs? What do you mean developed?
Please I am asking for your own words, not a cut and paste.
@Yodaweed your shit looks top shelf bruh, I would smoke yours first.

Meaning that it seems like the trichomes where harvested during the Capitate-Sessile stage instead of the of the Capitate-Stalked stage thus being not fully developed. Of course we can't see trichome heads from the naked eye but we all love buds with plenty of frost and if you see frost like my referenced picture then I think its safe to assume that the trichomes have reached the Capitate-stalked stage. I couldn't see frost until he had a close up pictures then with a 100x microscope you can see right away I have frost and its not even trimmed.

I heard from a very renowned Cannabis breeder that 72 hours of complete darkness before harvesting does wonders to plants. I have indeed tried it several times and it does change the taste completely… for the better! Why is this and what’s happening during those 72 hours?

As we all know, plants are dependent on light to conduct photosynthesis, which produces sugar, which in turn feeds the plant and allows it to live. But, to answer this question, let’s catalogue what can occur inside a plant in the dark:

• There is a subset of chemical reactions that occurs during photosynthesis called the dark reactions. In fact, they are also ultimately dependent on light (because five of the enzymes used in the dark reactions depend on light), but they can be carried out, or finished, in the dark (these reactions are also known as the Calvin Cycle). It is these dark reactions that produce carbohydrates (sugars). Think of these dark reactions as the terminal phase of photosynthesis. Those reactions can occur in the dark, but only for a short period before the light-dependent components of the reactions run out and photosynthesis shuts down.

• Mitochondrial respiration continues in the dark, but this is merely the release of carbon dioxide.

• The plant detects the absence of light, which it uses to set its circadian clock so that it “knows” when to flower.

In short, without light, most meaningful plant metabolism shuts down. There is a chance that something involving the plant’s circadian rhythm mechanism is changing its production of certain volatile compounds (think essential oils). This has been noted in the favorite test plant of botanists, Arabidopsis,1 but I am sure it has never been studied in Cannabis and I think it is a long shot.

Instead, I believe that what you are experiencing is a placebo or “nocebo” (since you are depriving rather than adding something) effect. I realize that this can be hard to accept, but I do not see any scientific basis for why this could be occurring.

Questions like yours are what fascinate me about Cannabis husbandry. There is a lot of myth associated with this plant and without controlled experiments we are left to conjecture. I would love to be wrong about your observation, and with decriminalization occurring, I believe we are on the cusp of sorting out what is lore from what is fact.

Science aside, I see no harm in the practice and no reason why you should stop if you firmly believe it is making a difference. Crazier things have been discovered!

How does forcing the plant to starve in its most productive budding phase eliminate "chemicals?" The plant will not have any unusually high amounts of trace elements if you keep your ppm/EC at a proper level. Plants always start to yellow and slow down whenever I would flush, which is not good at point where the plant needs those nutrients.

Besides name one other plant product that farmers flush before harvest, because I've looked and have yet to find one farmer of anything besides weed that even talks about, let alone actually, flush their plants. Even during my biology classes, yes Virginia some people on the interweb did go to college too, there was never any talk about flushing anything besides an over fertilized plant or other toxicities but not typical salts. I even asked a couple of my professors on several occasions and they basically said, "How does starving a healthy plant make sense?" And I'm sure one of my prof. knew why I was asking about flushing by the way he chuckled. So yeah, idiots.

I wasn't trying to attack your one idea with my original comment, just stating I used to believe flushing had a positive effect but it doesn't. While you assume us to be idiots, you're the one making himself look dumb. Cheers.

I typically just lower ppms to around 5-6 hundred for last week. I use general hydroponics three part and cut out the grow after about week 4 and then I cut the micro in half the last week. I ran cal-mag up until the end but lowered the amount last week as well. I also try to keep the ppms lower than 900-1000 the whole grow as well.

I provided 3 sources above about flushing above guess you missed that ,and your proof again did not state leaving the plants in the dark for 36hours it states that when you "take" the plant in the dark opposed to daytime there is an increase in thc content. Slow down before you read something and see what the person is actually saying!

Everyone has their own beliefs on how to grow why don't you test for yourself like I did, I have done a 1 week flush,2 week flush ,and molasses and kelp flush for 1 week sometimes 5 days. I find the plain water flush for 1-2weeks causes yellowing quicker and the weight and bud development was not the same because it seems like the branches couldn't pack on weight(plant is eating its reserves to stay alive instead of bud development). As far as taste and smell the kelp and molasses flush seems to be a winner and the weight was a couple oz more so yea try yourself and see.

I live in Colorado weed is legal here, I ask the dispensaries that have the best fire buds and they flush, they must not know how to grow too then even tho they are raking in millions and grow in 30,000 square foot warehouses?? Oh yeah you novices on the internet know more about growing then them. They invested millions have horticultural degrees but you guys know more because of a rollitup forum post I forgot...what idiots. I am personal friends with some of the best growers in Colorado I even have met some of the best breeders in the world but then again they all must be wrong.

I've learned that flushing means different ways by different people.
And how you grow. When you say flush I think lot's of water in a pot.
