THC is not 20% in the bud it is closer to 2 to 3 % .
the thc percentage given is in relation to the extracted oil during sampling not in relation to the bud .
during sampling the bud sample is ground to a powder and centrifuged in lab grade methanol for 4 hours and then strained through a 1 micron filter to remove all contaminants such as leaf .
the remaining oil is what is tested
the average percentage of oil is 15% as per the lab tech ( and anyone who had ever made bubble hash or rosin)
So got my THC test back from the lab today. The THC came back at 24.64 . ( thca+thc)
I asked the lab tech specifically does that mean I have 0.2464 grams THC in a gram ?
He said NO SIR , and preceded to explain the sampling procedure for the HPLC CHROMATOGRAPHY unit .
The 24.64% is based on extracted oil .

Below the HPLC chromatograph are two charts that highlight the cannabinoid potencies of your product. The first chart identifies cannabinoid concentrations (Fig. 3). As you can see, the delta-9-tetrahydrocannabinol (THC) level is 24.64 per cent (the product sample analyzed in this example is a cannabinoid extract, so the concentrations are much higher than what would occur in dried flowers).
I will post a pic of the sampling procedure .
I do not know why this is not known more widely?
it only makes sense. you can't have higher percentage thc % that the resin content of the plant.
the extracts are correct as their original mass is tested and not reduced ( no leaf)
