So as far as I understand it, the way they calculate THC potency is by taking a picture and counting the number of trichomes in say one square cm or inch?

Gas chromatography-mass spectrometry is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample.
Using Gas chromatography your marijuana is separated into each molecular component. Then by using Mass Spectrometry each component is individually weighed. The result is a ng/ml (nano-grams/milli-liters) measurement of every molecule present in your marijuana sample.
What I haven't been able to find is what is being used as the equation to determine percentage - is it: (the weight of the THC) / (the weight of the total marijuana sample: dried or wet?) ... or is it: (THC) / (weight of resin in sample) ... or is it, without using a GC-MS: (resin) / (total weight of sample ~ dry to get highest percentage)?
IMO THC percentages are the biggest load of bullshit a seed bank can shovel. Disingenuous at best. Look for a smoke report.

ps my money is on equation three.

Please don't send any stool samples....please. I'm only willing to test out flower samples"Send some samples my way and I'll be sure to let you know what I find!"
Uh .. ok man, but the post office isn't gonna appreciate delivering Stool-In-A-Cup.
Dude, asking people to send you their samples is kinda weird, in a disgusting kind of way.

. Thanks for the offer Hobbes, I should charge for my services, but I'll let this one slide for RIU guys!

I actually have an old school one of these in my garage. I need paper for the built in printer though

I heard somwhere that there were home kits for measuring thc content,maybe just bs ,any1 heard of these?

Ok so if this is the method then all of these independent grow shops have secret scientific labratories that they send there samples off too?
YEAH RIGHT.
Not only is that highly unlikely, but expensive as heck. I am with you, THC % would be a nice jewel of information to have to compare harvests but a completely non-feasible measuring method for the common man. Maybe if bill gates had a grow op it would happen.
I am not putting any stock into the % numbers i see on these sites anymore. And alot of them dont even care to list them. BCBUDDEPOT won 2 cannabis cups with godbud and the purps, nowhere does it list their relative THC %'s and nor should they.
Sounds like YET ANOTHER marketing gimmick. Isnt free enterprise wonderful?

MedicalMarijuana Inc. Has test kits that they sell to collectives to test THC levels.
this is how a lab does it http://www.unodc.org/unodc/en/data-and-analysis/bulletin/bulletin_1997-01-01_1_page008.html

Wow did you even look at the date?
Although I did seriously laugh out loud when i read the OP. "take a picture and count the trichomes" lolol
