I like your answer betterThere are several appointed stoners in every country that smoke every strain and make an educated calculation and provide the results to the breeders. The breeders then advertise the results.
Hope this helps
Thanks for the answer!Here you go: http://www.ukcia.org/library/skunk_strength.php
"The percent THC is the weight for weight of THC in the dry cannabis sample selected for analysis. A fresh cannabis plant contains a lower proportion
of THC as fresh plant material contains a lot of water.
THC is the main active constituent of cannabis. The.proportion of other constituents of cannabis is therefore not of interest in terms of potency.
The THC acid (delta-9-tetrahydrocannabinolic acid) is converted to THC when cannabis is heated (e.g. in a cigarette) so some scientists use gas chromatography (GC) analysis to measure THC. This method. effectively measures the total available THC, as the sample is heated in the injection port of the GC.
Ratios of cannabinoids are sometimes measured when comparing cannabis samples. The ratios are relative responses.obtained by the particular method of analysis and so do not directly relate to actual ratios of the percentage compositions. Absolute proportions of CBD would not normally be measured."
that is probably blood meal and bone meal answer ... ?There are several appointed stoners in every country that smoke every strain and make an educated calculation and provide the results to the breeders. The breeders then advertise the results.
