Elaborate on numbers my kind sir.
Weight is fairly reliable, yes. But much easier to just have a set it and forget it sop.

For a oven or a hot plate?
And for less than 30g starting material?
Idk I donât think HOURS is necessary?
I do not use an oven or hotplate but I decarb at 250F. The thca to thc only turns dark if you have exposure to oxygen. Depending on decarb mass (and catalytic effects of other stuff potentially in there) I would guess 1-50 hours decarb time and 3-12 hours being more likely for small amounts. Numerous variables like surface area, vacuum, catalystsâŚ
Edit: 30g is very small and I have no experience at that mass. You need analytical testing at this point.

Ok thank you for the information
Side quest: If it turned dark brown due to oxygen, does that mean a vessel seal problem ? Like a jar not being on tight enough/too loose?
Oxygen is just a molecule found everywhere there is air at 20.9%. It gets everywhere and oxidizes stuff but it keeps us alive, thank you plants. You would need to use a pressure vessel and purge the oxygen out with nitrogen or argon.
As in âshow your work pleaseââŚ.
Cool. Thatâs the correct answer. Which is a great start.
If you actually took weights, then providing them should be trivial (hence the âor it didnât happenâ).
same page yet?
lol⌠also appreciate that information.
Argon, heard 
Bubble mites probably tricked you into thinking you had a full decarbâŚ

lol⌠dude Iâm totally sorry.
I forgot where showing a before and after picture of my math will help us determine anything but if I made a mistake or not.
Picture this: 100g - 13g
Thatâs my work.
Read your page, didnât like the tone. Moved onto the next chapter
Iâm not the one having trouble with bubble mitesâŚ
I asked for your work (numbers) before you mentioned â13%ââŚ
And 100-13 is fucking awesome math from the guy who said he was playing with 25g.
trying to help.
You DONT seem to have achieved decarb. Getting the math wrong IS a formal possibility, asking to rule that out is not being a dickâŚbut you do you boo
I decarb 10-12kg at a time. 130C. Under vac. Takes me ~18hrs.

@cyclopath we decarb under vac also, around that temp, and it takes us twice the time for full decarb. Fortunately without oxygen the extra time under heat does not degrade the THC in a way that is perceivable via bioassay or analytical testing. Unless we are taking about the time a thca supplier left some zeolite based crc media in the thca and we did not notice until after the decarb.

removing bubble mites in the Rotovap at 160C
You can tell the solvent is all gone by the size and uniformity of the bubbles.
Most of the bubble mites are dead at this pointâŚmaybe another 10min or so.

There goes the SOP. Next thing you know Willbilly will write it up in a patent.

A new standard in âweedoâ: âregular on line bought terps.â
Very informative, thanks for the response and progression of the community. Couldnât do it without ya 
Nice decarb reactor!
Bubble mites are like fleas, they take a long time to drownâŚ

Has anyone tried rigging their reactor exhaust to bubble through a calcium hydroxide solution to confirm that CO2 is no longer being released?
