amber percentages, is it an educated guess?

Hi guys I hope these finds you well,

I've been reading a lot now people saying that they like to harvest their crops when they are at 20% amber trichomes, others like it with 10%, others even give a range like 15 to 25%. And I was wondering how are you guys counting your amber trichomes percentage? Is it just a guess or do you send samples to a lab? or do you guys use a counting method like taking a picture of a bud and expanding it and counting the trichomes that are visible?

Labs test it, that's how they know at dispensarys.

You can tell by smoking it if it's real strong or real weak, I doubt I could tell a 5% range though.

Other than that it is probably because they know that strain and know what it typically puts out if the grow goes well.

Kinda funny to throw percentages into the air then, but I get the idea. I wonder if counting will take too long? Or how long? Because you take a picture from different buds, like if you have 20 colas then take a picture of 5 colas, then count in the picture the trichomes, and get the percentage of each picture, then take the average of those percentages. How representative would that percentage be of your plant? Meh I guess the guessing method ain't so bad, but maybe ill count in my next harvest.

THC quantity is based on genetics not plant maturity. A plant's maturity, demonstrated by coloration of trichomes, determine type of high, hth. Cannabinoid content is usually done by chromatographic analysis but CN's the chemist let's ask him @cannabineer

you are right, I made the mistake of writing thc percentage instead of amber trichomes percentages, in my title and first post, I corrected them. thank you.

well i harvest as soon as as see 1% amber and hang them for a long cool dry and by the time they are cured they are about 25% amber

Gas and high-performance liquid* chromatography are the tools used, with the asterisked being preferred for precise values.

Start taking a test bud toward the end, quick dry and vape or smoke it. Start with mostly clear and if you don't like the high wait a week and try another one. When you get the high profile you like that's the trichome coloration you want to look for with that strain.

You'll never harvest at the right time if you do that. Trichomes are just a piece of the puzzle. People like to think they're being more scientific about harvesting when they say "cut at 30% amber" or something, but without the other harvest signs you'll just end up with premature bud. Harvesting by scoping for some % of amber is mostly bro science and nonsense that keeps being parroted by new growers that hear it someplace else. Read this: https://forum.grasscity.com/threads/a-guide-on-when-to-harvest.666373/. Once you break free of scopes and learn the true signs of ripeness, you'll never rely on a scope again for anything other than just one tool of many. Another thing that drives me nuts is people who think they can manipulate the high based on trichome color rather than type of strain.

I will surely let my plant go longer this time, and try to look for the signs of a ripe fruit. I'll tie myself to the bed if necessary.

I'm new, believed all that.
Looks like I need to make more room in my brain. Thanks.
