I read some technical description that decarbin needs 250F for a set amount of time, but with some observation of extracts tested with liquid chromatography, just using Iso/Acetone/Ethanol and adding a bit of water, and boiling off the water will fully decarb the extract. So, what I am saying, is just evaporating off the solvent with heat will decarb completely if it reaches water boiling point just for a bit. Seems contrary to the information out there, but this has been the lab testing results.
