I have done extensive archive searches in this forum to see if I could find out the ideal and optimal oven temperature setting and length of time in the oven, that will consistently yield the highest rate of THCA to TCH conversion, without overdoing it and having significant amounts of that precious THC degrading into CBD.
In reading the sheer variety of opinions on this subject, I was reminded of a quote attributed to Bob Dylan, in which he reportedly said " One thing I learned in college, is that a lot of people go to college."
I am also reminded of the words to an old country song by Don Williams, which includes the phrase " A panel of experts can shout all night, and never figure out which one is right."
Cutting to the chase, I found in the archives no less than TEN different recommended oven temperatures and oven decarb times, and I would like to list them all together here, so y'all can look 'em over and maybe help narrow down to a most favored decarb oven time and over temperature, which I can then carve in stone and use for the rest of all time.
Here are the various opinions that I found during my archive research in this cooking cannabis forum, regarding just how long to bake dry herb in the oven, and what temperature to set the oven.
100 degrees for 20 minutes
100 degrees for 60 minutes
150 degrees for 15 minutes
160 degrees for 5 minutes
160 degrees for 10 minutes
220 degrees for 20 minutes
275 degrees for 5 minutes
280 degrees for 20 minutes
300 degrees for 20 minutes
Microwave for 2 minutes
I wish I knew how to run a poll in my post here, but since I don't I sure would be grateful if as many of you canna-chefs as possible could look over the above listed oven times and temperatures, and help as best you can to identify the most THC-productive combination of time and temperature, selected from the above list I collated from past discussions in this forum on the subject, going back over a few years of ICMag forum archives.
Additionally I saw and noted in these forums a statement made that TCH "melts" at 260 degrees, and "boils" at 392 degrees. Can I take this to mean that it would be unwise to decarb weed at any temperature above 260 degrees ?
The subject of decarbing becomes more perplexing the more I read opinions on the best way to go about it, so a summary of sorts would be much appreciated by this aspiring canna-coconut oil alchemist.
