To your first question regarding decarbing twice, the Skunk Pharm chart shows that decarb takes a long time at 200º, so to ensure the THCa is converted to THC, I decarb it first. After decarb in the oven I use a crock pot on warm, which is in the 180-190º range.
Regarding heating pumpkin seed oil, what I've read involves "cooking" with it, which would indicate temps higher than 200º. I haven't used pumpkin seed oil yet but I have some on the way so I'll see how that goes. My last batch was fractionated coconut and grapeseed oil.
SweetSue's decarb/extraction process of 36 hours is for capsules to be ingested, not for massage oil. Additionally, I believe she has gone off that method after finding that the cannabis is still not decarbed after that time. After decarb, I did 4 hours on low in a small crock pot, 8 hours cooling, 3 more hours on low, cooled over night. I read that somewhere!
I hope this helps!
