Keeping this thread alive!

A couple new samples tested earlier this week.

Cannatonic
9-THC - 1.12%
8-THC - 1.09%
CBC - 0.00%
CBD - 14.12%
CBG - 0.03%
CBN - 0.31%
Total - 16.67%



Cheesequake
9-THC - 12.96%
8-THC - 0.00%
CBC - 0.00%
CBD - 0.18%
CBG - 0.08%
CBN - 0.50%
Total - 13.72%

I own dual column GC with FID/ECD. I used to have a lab in Gaylord area, now the equipment is in Bay City.

I have to say, Cannalytics is getting a bad rap here. Their equipment is unlike any other lab in the state. They use HPLC, which gives you both THCa and THC numbers. Given the same bud sample, THC numbers generated by a GC will be roughly 87% of the THCa number generated by an HPLC. I think they are now making the conversion for you on their reports so they won't get accused of inflating their numbers. I know the gentleman that runs Cannalytics, and inflating numbers is just something he wouldn't do.

Where HPLC shines is testing edibles and decarbed oils. It can give you the degree of decarboxylation where a GC can only give you the THC readings because a GC automatically decarbs any sample injected into the machine.

I never thought that any lab was inflating results but I did suspect that there was something like this making the results less than idea for comparison from lab to lab. Thanks for the explaination on that skirulz

You're welcome. I'm happy to answer any cannabis science related questions. If I don't have an answer, I can usually BS through it or find one for you. LOL.

Ironlabs stated to me their methods were most like the likely route of ingestion (smoking) and that is why they used the GC-most people will fully decarb thru combustion anyway. thoughts on that? I'm learning slowly but don't have a great chem/lab background; my limited science background was in animal research mostly and away from the real lab section of my facility.

That's not why I chose a GC over an HPLC, but that is sound reasoning. A GC is much easier to set up to look for a variety of analytes like terpenes, cannabinoids, and pesticides only performing minor, relatively inexpensive, modifications. HPLCs are somewhat limited in these areas without significant upgrades in detection equipment.

Neither machine is more or less accurate than the other when operated and maintained properly. Anyone who tries to tell you different is full of ish.

Do you know of a lab that does the terpene and pesticieds testing? I am not a member of Ironlabs so I don't see the whole report but the guys at the disp where I take tests to logged in and showed me the whole report and those 2 things are not in there for a standard plant material test. I am interested in the terpenes and if someone somewhere can show me a lab test that identifies the boogy man in hydro growing (any impurities or left over ferts or whatever that makes this "organic" shit soooo much better than hydro) I would love to see it. I don't think you can tell the difference and all these organic potsnobs are just tasting an inferior curing process and not some chemical shit from hydro.

Tumbling Dice Diagnostics in Bay City. Just google them.

It's virtually impossible to determine by Chromatography if something was organically grown or not. The only thing that may give you an indication is a pesticide test if the non-organic material is contaminated with non-organic pesticides.

Iron Labs does both, terpene and pesticide testing. What member name are your results under?

That's your tonic #4 huel? I'm at 30 days on my first round of her.

Mine actually isn't a #4 cut, its just another Cannatonic with the high CBD pheno found by seed. My cut actually tested higher CBD than 14 out the 15 Cannataonic #4 samples that Iron Labs has tested. Only the Cannatonic X from GLCCC tests higher. I'm hoping i can improve her even more on my next grow.
