THC % in weed is misrepresented. It is not 20% ( eg) it is closer to 2 or 3% .

Hello
so this post got me banned from 2 other forms. 700 hate messages. 4 death threats and an offer to fly to northern BC to fight a guy .I am hoping we can do better here.( read into that what you will :)
I would appreciate some ground rules. :
- no emojis
- no name calling
- no indirect name calling by negative comparisons ( ie my dog is smarter than you)
- please post references so we can discuss. Not everyone will be completely familiar with all the terms relating to testing such as hplc ( high pressure liquid chromatography) or the parts of the plants that contain thc such as trichomes.
ok , here is my first question to be explained:

if 100 grams of weed is rated at 20% thc then that should mean 20g thc
but the most resin (trichomes ) I have ever harvested or heard of anyone harvesting
is around 15 % ( my observations have been 10 to 15% trichomes back from seiving or ice water crystal extraction. I have never read of any higher) .
I know that the thc needs to be decarboxylted? to turn the thca to thc .
let's assume that 100 % of all thc analogues are converted successfully for sake of math .
where does the 20grams of thc come from if the trichomes that produce them ( in the head cell according R Clark in Marijuanna Botony ) when those trichomes are NOT 100% thc .they also contain terpenes and calcium carbonate.
the common belief math is
100 grams weed at 20% thc should be 20 grams of thc ,
so where does the 20 grams of thc come from if trichomes are 15% max ? how can that be ? it can't.
the mistake is NO ONE POSTS THE PROCEDURE FOR TAKING SAMPLES FOR HPLC. IT REQUIRES THE SAMPLE TO BE PROCESSED TO REMOVE LEAF AND THE TRICHOMES SEPERATED AND DISSOLVED IN LAB GRADE METHANOL.
The THC content is rated based on the extracted trichomes NOT the weed
it's the trichome that is 20% THC NOT the leaf matter .
so the actual math is :
100 gram weed rated at 20% thc
contains 15% of trichomes that produce the thc as well as terpenes and calcium carbonate. the thc level is 20%
the actual math is .
100 grams weed at thc 20%
15 gram trichomes at 20% thc
100x 0.15 = 15 grams x 20% = 3gram thc
5here is 3 gram thc in 100 gram weed which makes weed 3% thc NOT 20 % .
it is a misrepresentation based on no disclosure of testing procedure .
bottom line..weed is 3% at best thc NOT 20%
how could you get 20grams of thc out of 15 grams trichomes.?
that would contravene the law of physics and the law of CONSERVATION of mass and ENERGY .

let the games begin but try to be polite please:)

I've actually wondered this myself but then how do you explain that when you press weed, you get a yield of 10% of the weight of the flower you press and the rosin is around 75% thc?
After pressing 100 grams at 20% thc, you get roughly 10 grams of rosin which is 75% thc so you end up with 7.5 grams of thc and there is still some left in the flower.

Yeah as you mentioned there is some left in the flower, and that loss can account for some of the difference we are seeing.
That being said I agree that lab testing is bullshit, because they are testing sample nugs, not the actual nugs you are receiving. Their is no way to tell the thc of the nug you are receiving, without making the faulty assumption that the thc concentration is homogenous across the batch.

My point wasn't that there was missing thc, it was that the 7.5g is more than 3g.

2-3%?

I dunno man... Ive done a lot of extractions, and tested a ton of them.

Last one i did I extracted 48 grams of oil from 10oz, and the oil came back at 87% cannabinoid and 84thc%. Putting it around 14% thc extraction from 10 oz. And i likely left some behind.

hello Aaron
so first. thank you for the civility.
question. how do you know the rosin is 75 % ? if the rosin is melted resin it should still be the same % . the only way 20% thc can change to 75% thc the concentration must increase by 3.75x .( 75/20) there is no extraction or separation going on as far as the rosin goes. the only thing you are doing is separating the rosin from 4h3 leaf matter. there is no purification of the actual resin such as an alcohol extraction. the math says that the rosin has to the same thc % as the trichomes it made from . I make 79% thc oil and it requires separating the resin from leaf by water extraction as well as screening between 150/50 micron. I get close t0 15 % resin back from weed .now this is still just 20% thc because the leaf matter was never part of 4hr equation. I took resin that was 20 % thc off a substance that has no thc . as far as math I increased the 3 % leaf /resin mix and increased the percentage from 3 % TO 20% by the removal of the leaf. now I out in in 95 % ethanol. then filter out solids and waxs. distill off alcohol and I am left with now 2.5 gram of 80% ish thc from 10 gram resin.
so the rosin could not be 75 % thc either . how do you do testing ..I am hoping it's not the Tcheck device.. that is my next page .they are a fraudulent device . they do not test thc. they are a VOC ( volatile organic compound meter. they test bio gas) the spectral reduction of a gas or vapour between the test led and the receiving sensor interprets disturbance and light reduction as a percentage of vapour . then the data base sends a description of what they say that strain is .it does not test anything. you send a reading and it sends back pre written responses based on other testing noting to do with the sample sent. like using a flash light to make a shadow and sending a pic of that shadow to a company that then tells you how much weed you got based on other pictures of shadows in their data base

but ...if there is skepticism then show the math. I do get mine tested as required by health canada as required under the licensing act . not just for thc but pesticides.
I know most dont agree ..so show me the math .
100 gram weed
how much potential trichome?
100 gram weed at 20 % thc =20 gram thc .
ok 85 gram leaf with 15 gram resin at 100% thc ? not possible
80 gram leaf with 20 gram resin that is 100% thc ? not likely.
75 gram leaf with 25 gram resin at 80% thc ? maybe but unlikely.
50 gram leaf with 50 gram resin at 40% thc ? nope
now let's look at resin itself..
how much oil do you get back from 10 gram trichomes? 50 % ? no
usually 30? and not pure thc and the leftover resin is devoid of thc

just show the math

Hmm that's actually true. I'm unfamiliar with how thc potency is tested but what about distillate, it is tested at sometimes 99%+. According to what you're saying, would that mean it too is only 15% thc? Distillate doesn't contain terpenes so what would make up the other 85%?

My method of dry ice kief /oil mix yields about 25% of I'm guessing 50% thc. But I'm sure I'm not getting it all. And I don't care about lab tests. But yeah, still more than 3%.
ok so show the math . you get more than 75% of your kief back as oil ?
if thc 50% and oil comes back at even 80 you still need 70 to 80% substance back

I do not doubt distillate is 95% . it does not speak to the percentage of the original product only to th4 the percentage it was extracted to. .. you can get 95% alcohol form a variety of sources such as beer 5% ( Canada) wine 12% you just need more beer than wine but the end result is the same.
I make distilling systems on the side .we dona lot of hand sanitizer. I am just doing a unit for a legal grow and they ( who don't even. smoke ) were very upset when I told 4hem ...and showed them that their 20% product did not yield the 20 g per 100g but 2.6 gram. I built a small vacuum still . it is small version of comm3xsil they would need to do the ( way 5oo much to mention on this site ) amount they have

So you'd only obtain a max yield of 2-3g of distillate from 100g of flower?

As someone who personally knows someone that operarates a short path fractional distillation rig, i can attest to this being not true. He fractions returns of about 7% using tight trim or about 10% on average using flower. 2-3g distillate returns are what i would expect from leaf.

Has anybody else made distillate and had a higher final yield than 3%?
I also asked 4his question but about resin % on gra$$city but neve got one straight answer . I hope we fair better..
also may3 resin ? how much resin or crystals have you got back ? anyone?
