Extraction Decarbing before making cannaoil?

[pop22]

Thanks for the advise Pop! So what you're saying is that I can decarb in oil, it will just take longer to fully decarb that way?

About the temp on the slow cooker, yeah I agree. Perhaps I should have it on high for an hour to let it heat up and then turn it to low for another 8 to decarb? Or I could take 20 min and decarb in the oven 1st and then I don't have to leave it in the slow cooker for as long and just keep it on low. Am I on track here?



DAMN! That would make some potent ass oil I would imagine!

No, I much prefer decarbing in the oven and cooking at 190F that way, decarb is already at its highest and the cooking temp won't increase or decrease active THC, This gives plently of time to cook all the cannabinoids out of the plant matter. Ir, you can cook at 1900-200F then decarb the oil in the oven at 250F for 27 minutes.

I now cook in a double boiler. You'd be suprised how well you can cintrol the temp of the oil this way. I use a candy thermometer to set and maintain the cooking temp. I can get it to exactly 190f and keep it there with this, inexpensive method. This way, I'm getting consistent batches of oil with the only variations being created by using different strains, but my oil is consistently potent.

Awesome bro, thanks for the info! I'm getting what you're saying haha.

How to Decarboxylate Weed

Raw cannabis contains a lot of THCA which is not psychoactive (and what's the fun in that?). When you smoke weed, the THCA molecule loses its carboxylic group (COOH) in the form of water vapor and carbon dioxide and becomes THC. Long story short, THCA becomes THC and your cannabis becomes psychoactive. This process is calleddecarboxylation or decarbing.


When you smoke or vaporize marijuana, the cannabis is decarbed by the heat. If you ingest cannabis and want the full psychoactive effect, you need to first decarb your cannabis before you cook with it.

Temperature
The lower the temperature, the longer it's going to take to decarb your cannabis.
Keep in mind that a lower temperature will allow you to lose fewer terpenes.

What are Terpenes?
Terpenes are the pungent oils that color your cannabis with distinctive flavors such as berry, mint, citrus and pine. There are many medicinal benefits to terpenes; some will successfully relieve your stress while others will promote focus and awareness.

Decarboxylation Methods:

​

Flower / Buds

1. Preheat your oven (see table above). Use an oven thermometer to check the temperature.
2. Break down the large buds with your hands
3. Distribute evenly across the pan
4. Place in the oven
5. Check on it after 20, 30 and 40 minutes (don't open the door fully)
6. Make sure it's toasting evenly
7. After 40 minutes it should be done - golden brown

Keif/Hash

1. Preheat oven (see table)
2. Sprinkle hash/keif on pie plate, cover with silver foil and crimp foil along edge of plate. Place sealed dish in oven for (see table).
3. Remove plate and let it cool down slowly without removing cover to allow any vapors to reabsorb into cannabis.

Boiling Bag method:

1. Place the cannabis flower/keif/hash into a boilable cooking pouch. Seal it.
2. Place in boiling water for 90 minutes. Make sure water does not boil dry.
3. Take bag out of water. Let it slowly cool before opening.

Cannabis Oil

1. Place heat proof container of cannabis oil into a cooking oil bath (canola oil works well). Heat cooking oil to 121C/250F.
2. Stir cannabis oil to break up bubbles.
3. Remove cannabis oil from heat when bubble formation starts to slow down — or leave on heat until all bubbles stop for increased sedative effect.

If you go back and look at the graph, you'll see he's WAY over cooking during decarb and losing a lot of thc. That graph was from a scientific type study of the decarb process. Once again we see there are too many "experts" . I'll bet you can find 20 different oil recipes that use 20 different decarb time/temp combos. they can't all be right/ I make a LOT of oil and I've found that going by the chart, cooking at 252F for 27 minutes always give consistently potent oil. I am planning to do some experiments ( not to any strict scientific standard ). I plan to decarb as I always do. I'll take samples of the oil at various cooking times: 30min, 1hr, 1.5hrs, etc. the I'll take capsules from each batch over a period of days to see if there is a peak point for cooking your oil. Temperature of the oil will be measured throughout the cooking process with a candy thermometer to help maintain even temps ( I do this already ) What I'm hoping to accomplish is a solid, repeatable baseline for making canna oils.

 

[pop22]

let me clarify one thing, I've no way to get my oven to 252F. O got an oven thermometer and get my oven to 250F, and decarb for 27 minutes as I'm sure the 2F doesn't make a lot of difference maybe 1-2%? I'm planning on getting a fondue pot so that I can cook in an oil bath, as per skunkpharm research, then using a candy thermometer, I can get an accurate bath temp for decarbing. It will also be a better way to cook as you can get the temp at 190F and cook without your bath fluid evaporating and much better temp control than even my double boiler method.

Is there any reason to Decarb ABV ? I currently have about a cup of ABV soaking in 1.25 cups of Ever Clear 190 proof ... plan on leaving it about a week and then straining it ... after straining it, I may not evaporate the alcohol and instead use it by mixing it in coffee or other beverages ... anybody know if it should work ??

Couple picks of my ABV ... 380*F for about 7-8 min ...

No reason to decarb AVB, its already been done when vaped

 

[tag60435]

So, is ABV a good source for the foundation of some oil? I have read random references at several sites that list ABV as possible source material. So I was wondering if I should go ahead and cook some up. To my thinking, based on some charts and scientific writings on cannabinoids/terpenes and temperature profiles, ABV should be fairly low in most of the THC constituents as the normal temps for vaporizing are 350--390 which coincides with most of the THC. Leaving the CBD constituents mainly untouched since the require higher temps to volatize. Is my mind on the right track? Or should I slow down in my production of ABV source material:Hookah:

We have been vaping an early harvested Dinafem Original Amnesia Auto, which is described as being medium/high thc (9-13%) and medium cbd. (no measurement given) Since we only dramatically lowered thc levels, why not get the most from the plant and turn it into another product.

This weekend I've been working on making my cannaoil.

I decarbed about half O of popcorn buds and half O of good quality trim.
I set my oven to 240 (to compensate for oven thermo) and baked for 30 min.
I took the popcorn buds and put em in my crockpot and let them cook in the oil on low for 6.5 hrs.
I strained it out using cheesecloth, a mesh strainer, and a nylon pantyhose for extra fine quality oil.
Then I took the other half of trim and put them in the crockpot and used only the same oil that I just strained.
I let this cook on low for another 6.5 hrs and once again strained as above. I got 2 cups of some nice potent oil.
Which I then used to make a few desserts. Oatmeal choc chips & "Cannasquares" a modified version of a family favorite.
I've sampled a few cookies and am baked. My first time making edibles.

I have never de-carbed. I had made cannabutter a couple times before I heard of it, and the only problem I had was getting too stoned. Since I wanted a good cbd-THC ratio for the medicine, it wasn't an issue.

But even the intent wasn't medical, it was still far too easy to get overly stoned.

Truth in advertising moment, I am more of an indica guy than a sativa guy to begin with, so YMMV.
