In actuality, if you track the temps of typical baked goods in the usually recommended 350* baking environment you will find that the food rarely exceeds the temperature of boiling water. Until you bake off all the moisture that's where the heat will max out, hence the advisability of pre-decarbing your material before cooking - especially with baking/heating times of less than 30min.

Eclipse 420 I am very grateful for your providing this detailed, scientifically derived information on this subject.

This is just the sort of definitive study that I can pore over, and use to formulate a plan for success with my decarb experiments. I am cutting and pasting this precious information now, for future reference.

Once again I sure do appreciate this wealth of data, and I really do now feel that with this information, I can impart a little more method to my mad dabbling in this dark art he he.

Swamp, go to the patent link...both pdf & text versions available.

BTW, from what I can see, the relationship between temp and time is linear...in other words, plot the published data points on a graph and you will see the relationship between temp and time is almost a straight line. Example suppose your temp is only 210...not 220, the graph will indicate the appropriate "time" for 210 degrees.

I no longer "extract" so--it has a few years since I decarbed...but it is something I would consider should I ever grow a crop of substandard "weed"....decarb it first then have it blown.

That patent document does make for some daunting reading, Eclipse420, with the array of research data presented, but I can see that Table 4, reproduced from that paper in your post above, does indicate that the final TCH content produced by heating the buds reaches a maximum value only at a temperature of 105 degrees Celsius (216 degrees Fahrenheit), and after 2 hours of heating at that constant temperature.

Despite seeing these figures, I am still a bit hesitant to leave my buds in the oven for as long as 2 hours, for fear of converting too much THC to CBD, so I will try decarbing a small test batch of weed at 220 degrees ( my oven's closest setting to the optimum temperature of 216 degrees Celsius) for a duration of 90 minutes, before using it to make up some canna-coconut oil in my crock pot in the usual way, to see how the results compare to my previous efforts.

Once again I thank you for helping clear the fog so that my efforts can become a bit more focused towards replicating, or at least approximating laboratory-established findings regarding the most effective procedure that will maximize the THC content of my canna coconut oil.

Exactly....do a test batch and see what you get. Maybe a series of "tests"....like 5-10 grams per mason and start pulling them at specific intervals (I did 10 minutes a part)--then compare. I was amazed and surprised of the difference that 10 minutes made...each batch was similar but quite different.

The patent is a tough read...but focus on the "decarb" discussion--super critical CO2 processing is interesting, but of no value for decarbing. It jumps around a few spots (yellow highlighter) and it took me about a dozen reads before I actually understood what "I know"....lol. So, smoke a fatty and don't be bashful if you find yourself reading the same paragraph over and over.

Also...the lower the temp, the longer time duration---the higher the temp, the shorter time duration. Like I said, it is linear. Same...same.

Wow this is really interesting.

Thanks for the info.

I used this from SkunkPharm. Their website has a very well done explanation of a bullet proof method to decarb extracts. I have never decarbed flowers before, I have never had a need to. But I imagine the same graph still applies. It will just be harder to know if/when everything is done decarbing.

Excellent info, thanks everyone.

hot fast decarb seems where it is at.....

I do the crock pot method half the time with water....6+hours...

I have also done the quick heat butter only style watching for the bubbles....Seemed to be similar potency...but I know I am missing some as I have had some variation in the batches, dispite using the same material. Time being the difference...tried 8 hours....tried 4 hours...tried with water, without...

Seems easier to extract then decarb imho...just costs more.
