I made some BhO then sent it to the lab.......

It actually appears you did score over 80% cannabinoid mass because it's 73$ THCA and 8% THC.. I'd have to do the actual math to check but the 72.8 score appears to be taking into account the loss of weight from THCA converting to THC. Basically 100% pure THCA is only capable of producing about 85% mass of THC since 15% of the weight of THCA is a formic acid moiety.

I have no clue how to calculate those percentages... I just know how to make the concentrate....

Nice color..THC content is insane!

Strange, death star in the midwest has plenty of other cannabinoids. Wheredid your flowers test?

 

[FouRtwizzle]

I did not test the flowers. I did not grow them. I'm just using friends trim for now doing 50/50 splits. I will not have any of my own trim until the end of the outdoor season.

I think the flowers were harvested at week 11 they should prob go to week 13-14 in order to allow the other cannabinoids to develop.

IME, hexane extracts have significantly higher CBDA content than butane extracts. I'm not sure if it's the differences between the solvents or the typically longer soak times with hexane. You should try the same material but with a longer soak time/thermos method. I'd be willing to wager that CBDA has a slower dissolution rate in butane than THCA and this is amplified when it's occurring in much lower concentrations in the plant material. With Hexane extracts however, I've had noticeable increases in CBD/THC ratio over the original plant material. That said, I believe there's something fishy with the CBD testing methodologies being used as I've seen extreme variances in CBD content between tests from the same lab and chunk of extract.

 

[FouRtwizzle]

ive never tried a hexane extraction.

Is this the type of haze e you'd reccommend?

I've never used the "soak" method either.

Would I simply use the quick wash ISO method replacing the ISO with hexane?

Agreed. Until the testing and the calibration of the machine is regulated by some entity, there will be grand differences on the regular.

Yeah, USP hexane should be fine. Some only use analytical grade, but USP grade is fine to me. The main thing is that it should be free of benzene. If Benzene shows up on the MSDS or COA then definitely stay away. I'm guessing the main difference between USP grade and analytical grade is the USP will allow the presence of more similar n-alkanes and various isomers whereas analytical grade is just high purity n-hexane. For food/medicinal solvent purposes USP grade should meet all of your requirements.

You use hexane pretty much the same as you use butane. Some say that longer soak times of about a day with hexane are better and that is true if you want to extract nearly all of the THC but I've found about 30 minutes to an hour in a cooler with dry ice or freezer gives the highest purity/yield returns, ideally you want to use freshly frozen, never dried flowers/trim as with butane. In order to stretch your hexane further, you can run the solvent through two trim batches since it stays liquid at room temperature, although it will lower your yields a little unless you squeeze all of the hexane out of the trim on the second batch.

Don't quick wash, thats to limit chlorophyll absorbtion and hexane wont do that anyway. Let it soak for a bit and always wash a second time for good measure.

 

[Persephone]

Very nice FouRtwizzle, beautiful colour.

Wish I had access to a lab down here, I'd love to test some of my refinements.
Thanks for posting your results.

Cheers,
P.

 

[pip313]

Use dry trim it matters
Water and hexane = chlorophyll extraction even the water in the leaves

If you want to take advantage of hexane and ethanols azeotrope to purge the hexane whjch is what I do you have to use n-hexane not "hexanes"

From what i have seen, CBD extraction requires a soak for maximum results. My belief is that the wax jacket on the CBD trichome is thicker and takes longer to dissolve and release it's contents. Longer soaks do seem to raise the CBD/THC ratio beyond that of the flower used for processing...

Please do elaborate on your belief that individual cannabinoids are deposited/synthesized in different trichomes and also have morphological differences.

It's my understanding that the same trichomes make either or both, but the differences in THC, CBD, and CBN composition may make make them dissolve at a different rate in the same solvent.

There is enough difference that they don't come out of the GC column at the same rate.

beautiful stuff man!

I just did a run of 500g's with 14 cans of vector and I wasn't really impressed with the yield.
56 grams. Using 1" dia ss tubing 12" long

I actually saved all the material and was considering doing a thermos soak with it.
I'm not sure how long to soak it.. Would I put it in the freezer while soaking? Like the winterization technique?

I've never done a 2nd run of my material before. I've always thrown it away. But I'm thinking this material might have something worth while left in it.

It's possible it could be rich in CBN & CBD as it only takes about 3.5 minutes for the can of tane to run through the tube. So the exposure to the butane is minimal.

 

[SpaceshipNelson]

I'd keep it in the freezer during soak, so your butane behaves itself and maintains liquid form. Then you can soak as little, or as long as you like.. (Remember all the iso's/pentane/propane will still boil off into gas, so ventilate your freezing area accordingly).

 

[midwestHIGHS]

DO NOT PUT A THERMOS FILLED WITH BUTANE IN THE FREEZER. Thermos exrtaction, is not the same as winterizing. All thermos extractions should be done outside, with the use of dry ice, regular ice or mother nature, to keep the butane below its boiling point.

I'll say this one more time, do NOT put a thermos filled with butane in your freezer, I've seen many pictures of freezers or refridgerators blown to bits because of this.
