Sick. Eden Labs sells the CO2 and Tamisium sells the BHO extractors.Met a guy who does oxygen wax. Had no idea how complicated it was. The machine he uses to make it ran him $50k. Crazy shit. Picked some up. Looks super tasty.

Who is GW?uh... who are you and where have you been all this time!?! welcome!
Interesting about Full Spectrum. They shut down. In my opinion they were data mining, and I have good reason to believe the data is already sold to GW
[FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif]UKCIA question: [/FONT] [FONT=Arial, Helvetica, sans-serif] Further to a phone chat today (Thursday 19th May) to one of your people[/FONT]
[FONT=Arial, Helvetica, sans-serif] I've been hearing a lot about the strength of cannabis of late. This strength has been quoted as "percent THC", can you explain what this means?[/FONT]
[FONT=Arial, Helvetica, sans-serif] With alcohol, strength is measured in percent alcohol by volume (%ABV), but clearly the THC in cannabis doesn't amount to 10% of the volume nor of the weight, so what is it a percentage of?[/FONT]
[FONT=Arial, Helvetica, sans-serif] As a follow-up question, cannabis isn't simply THC, the other main component is CBD which is known to modify the effects of THC. I have also
seen this ratio reported as a percentage, so how is the ratio of THC to CBD measured?[/FONT]
[FONT=Arial, Helvetica, sans-serif] Many thanks[/FONT]

[FONT=Arial, Helvetica, sans-serif] 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.[/FONT]
[FONT=Arial, Helvetica, sans-serif] 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.[/FONT]
[FONT=Arial, Helvetica, sans-serif] 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.[/FONT]

They are talking about the ratios of canibinoids, not the ratio of thc to plant matter. If you want to prove the guys at the lab wrong, you'll have to find something better than this.[FONT=Arial, Helvetica, sans-serif]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.

[/FONT]"So the measurement they make is a percentage by weight of the oils in the sample, not of the overall weight of the sample." This statement was made to explain Mullins statement to people with low reading cmprehension. The article was written by a marijuana activist group but the information was obtained from a government agency that's dealing with the regulation of marijuana in the UK not some idiot trying to profit off of medical marijuana and is why it's more reliable.
new word for our friend: FAILTALITY!They are talking about the ratios of canibinoids, not the ratio of thc to plant matter. If you want to prove the guys at the lab wrong, you'll have to find something better than this.
That's exactly my point and is what these test give results for. None of these tests mentioned give ratio's compared to plant matter and that's why they are being misleading. If you want to go on thinking cannabis is capable of structurally being 25% THC by volume then go ahead but it just shows your ignorance. If a sample of marijuana tests at 25% then it means 25% of the oils are made up of thc not 25% of the plant matter. On the example where the hash tested at 90% and it was a 90 micron hash it tested high because it was a refined hash. I guarantee you that if the hash was tested using a 120 micron filter it wouldn't be 90% but more along the lines of the high 20's. Testing bulk hash would give you a more equivalent view of what a strain can produce and is why when you see bulk hash test results the results are more congruent to the numbers you see when plant matter that's been tested. Show me one test result where 120 micron/bulk hash has tested anywhere close to 90%.They are talking about the ratios of canibinoids, not the ratio of thc to plant matter.

They are not testing against plant matter only oils, it's not how these tests work.Percentage results generally represent a percent of total sample size.
When using a GC, the sample must be first run through a dehydration unit, to account for total water weight. So, 10% THC is also 100mg/g THC minus water weight.
I become skeptical at any flower results over 20%. Hash I begin to doubt over the 60% mark. Not that these numbers do not happen, just not likely, and more likely to be a lab/human error. And of course, only a partial dehydration can be reached, as 100% dehydration doesn't happen, we'd be left with dust.
Man, he's been on this trip for over a year now. I told him this is what I studied in school specifically. He denies what FSL published on the topic too. Ya know.Which tests? HPLC? GC?
The labs I am most familiar with, are all reporting results based on total (dried) flower weight.
