Yeah, probably. That’s why the folks at harvest direct are using inert gasses in there. Pressure cooking with O2 around isn’t going to do the terps any favours.
care to elaborate?
sure. but I’ve got no data on how yet, and I haven’t gone looking for anyone else’s yet. presumably trapping the CO2 will have some effect on the reaction at some concentration. perhaps not at the concentrations I’ll see. don’t know.
based on the diagram on harvest direct’s website, presumably going above the 40 PSI at 100C I would expect to see if I left a little ethanol in there is appropriate. I can safely manage 120PSI with parts on hand.
might have. not sure I understand how.
I made a couple of tries, I was happy with the results.
used a coffee warmer and 4"x6" tri-clamp spool. Should have put a gauge on there. will next time.
real issue is that I’ll need some way of determining % decarb, and my bioassay team isn’t quite well enough calibrated. they can all tell 50% from 100%, and 10% from 0% if I dose them right, but their 90% to 100% is pretty iffy. 
I figure I’ll throw $160 of TLC kit at it and see how far I’ve gotten. then re-evaluate. I think I could calibrate an old school UV/Vis spec to distinguish THC/THCA and CBD/CBDA, but working that up just to get the decarb solved seems like the long way around. it is still attractive long term if I can’t swing an in-house HPLC
Edit: CBDa decarb kinetics and more (PDF in comments) thanks @slooty
Edit: these critters are about $15k and look fairly useful to have around. essentially mini-LC with Diode array detection and some embedded analytics.
