In your personal experience do you go by the small leafs closest to the bud, or do you actually check the bud it self(calyx)

I check the leaves closest to the bud, from top, middle and bottom.

Well for years the way I've learned is looking at the small leafs all over a cola, alot of people I know do this also. But recently I've been going by the calyxs trichome instead and noticing my plants can sometimes go up to 2-3 weeks more before I notice a change in trichome color. So basically by the time the Caylx trichomes are no long all clear and have some color, the leaf will have all red/popped trichomes.

Most people search all over the whole Cola noticing lots of cloudy/amber on leafs and end up pulling it when the bud is still fully clear.

I look mostly at how big the trichs are getting and wait until they are full. I want the bud to be fully developed and ripe with big trichs on it so that's what I wait for.

Trichomes & Harvesting

[indent]Harvesting your weed based on trichomes is probably the easiest way for most growers to harvest as close to peak harvest as possible.

The difficulty in the method comes with how to determining the state of the trichomes and what each state means.
If you have the equipment needed however it is very easy and with experience it gets even easier.

To explain how to harvest by trichomes Properly I will go into detail as to how to determining When trichomes are at peak and Their All which substances thesis trichomes containerization, All which are desirable and All which are not.

The first thing you need to know Is that there are three "states" in a development trichomes.

The first state is clear. Clear trichomes containerization precursor cannabinoids (cannabinoids are the different substances in cannabis).
These precursor cannabinoids are not psychoactive (they do not produce a "high") and harvesting yet clear trichomes will not give you a clean harvest.

The second state is cloudy / milky. Cloudy trichomes containerization Fully Realized THC (the main contributing by far any substance in cannabis high).
You want to get as close to 100% cloudy trichomes @ harvest to get the most out of your potency plant. It's impossible to get 100% cloudy trichomes, since trichomes are always being produced and are always maturing, just after harvest the trichomes will continued to develop.

The third state is amber. Amber trichomes containerization degraded THC -> CBN. CBN Represents a 90% loss of potency (from THC).
CBN is not desirable in any harvest, since it not only represents entry a huge loss of potency but research into the substance has Also Shown That CBN does not produce a high like THC does, CBN Produces a more sickly feeling not a true high.

Understanding the difference between clear - cloudy - amber trichomes is essential in getting a proper harvest with a peak potency.

This image is a good helper to remember the differences:

To understand how substances change and are developed in cannabis you will need to read Extensively on each substance to understand what each substance does and how they affect eachother.

This image is helpful in getting a vague knowledge of Substances in cannabis and how they develop:

I will not go deeper into what each substance (CBG, CBD, CBC, CBN, THCV etc) Thu, suffice to say they all play a part in the cannabis high, albeit a minor part for most of them, since THC is the main factor in a cannabis high.
Some bieden pain relief, reducing muscle spasm some, the list goes on and research is still being done to figure out all of the benefits or thesis substances.

I can however post an image rather well That Explains All which effects the substances have on the human body:

Trichomes are of course not the only indicator of when to harvest.
There are other factors That Should be taken into account When Determining when to harvest.

Calyxes on the plant will swell up, thesis swollen calyxes are a sign of maturity.
The Pistils (what some new growers call hairs) will change color (often to an orange tinge) and recede into the calyx.
Pistils are receding Also a sign of maturity.
Then there is the overall look of the plant. Many experienced growers simply go by this factor, they can determining peak harvest just by looking at the plant and seeing how it looks from afar Regarding color tinge and the look of the calyxes.

All thesis Factors Should be taken into account When harvesting. All of thesis factors Usally alignments When peak harvest approaches.

The best way to check how the trichomes on your plant are doing is by Means of a magnifying glass or a microscope.
I would recommend getting Ones That can at least go to 60x magnification.
Getting One that can go to 100x would be even better, but the more magnification the more cost.

All you have to do is take a small sample of a leaf with trichomes on it, or if you have a loupe or a USB microscope simply look at the trichomes on the plant to determining Their 'state'.
It's important That You check all over the plant, since trichomes Usally will develop and produce faster at the top (s) or branches and slower and the bottom of the plant.

Some people choose to harvest the tops first and let the bottom nugs grow a bit more to let the trichomes mature and develop further Top lieve but let the buds fatten up more. It's a judgment call and preference really.

It's almost impossible to harvest without at least some amber trichomes (and some clear), keeping the amber trichomes to the minimum is key if you want maximum potency out of your plant.
Usally if you are careful and watchful you will end up with around 5% clear trichomes, 10% amber and 85% cloudy trichomes.
That is a very reasonable and% split is what you Should be aiming for.

Quote from rev "Amber = past ripe, that color is rust from oxydization. You know anyone who let's their vegetables or fruit rot before harvesting?

The plants that I made that 'unclean' hash from were harvested as close to ripe as possible 5% clear, 90% frost and 5% amber. It's the absolute closest I could get to peak"

very nice one, ink. that's how it's done. and they're
great contributions of the others as well, of course.


(yo, ink ... you get my first "like this" click, mate :))



so far i have been doing it like rev and 4fourhorse described.

Hello,

Just like some trees, fruits of the same plant are not necessary all ripe at the same time, and some strains may have variation regarding the place of the bud. Some ripe by the top, other from the bottom, not rare to have a half of the plant ready a week or two before other part more or less exposed to light, airwind or cold/hot. Trichome observation (of what you smoke naturally, so not the leafes :) is the only way )

That approach will net you a more even harvest santero.

Just to reiterate why I use leaflets, we don't want to do too much damage to the buds themselves when pressing up the business end of the scope (I use 40x's).

Then it's simple math. From the top, bottom and middle leaflets, I count the trichomes and write down for example: 5 clear heads, 30 opaque/frosty heads, 2 amber heads. I take the mean average of the three positions together and base my harvest on those numbers. I've been asked many times here in PM's, "dude how can you nail down such precise trichcome counts....well that's how I do it. More times than not, when I get to really know a plant I can get 95% frosty trichomes +/- 5%. This is not an absolute science but it's what I'd like to see most people do when harvesting.

Arf Rev', i 'm much more "instinctive" and not that precise. I check (and shake too :P ) with a x30 once, or most of time a macro picture is good enough, i just "feel" how it is :"mostly" like this or like that, and it is enough for me.

Whatever works LVR, this is just how I do it and there are definitely more approaches out there :)

The only reason why I do not scope bud level or calyx's for trichomes is because I grow small personal med batches and don't want to 1)crush buds that might not be ready yet and 2) I don't want to introduce pathogens, bacteria...anything that can adversely affect the outcome.

Cheers,
RM

What about the thing it does continue to mature when cut. If you close look at cure buds, all trichome are brown, despite it is harvest clear or translucide Is there any studies about that ? It make sense, as fruits continue to mature harvested, but for sure metabolism is not the same (sugar production, exhausted taste). How long does the ripeness continue after harvest, héhé ?

Vibes to all, the ones you need ;)

Edit : an other enigm, i harvested my Coljam in 3 sample from 16th to 19th weeks. Each sample had the same trichome aspect, half cloudy, half amber, but the 16th and 19th doesn't have the same effect at all, despite the fact you'll can see difference in the trichomes colour between 16 and 19th when i picked them up. So for me, there is something else (no - no, i don't want to re-invent the wheel, just try to understand more complicated aspects of chimie )
