Hi help4dad,
Hope you're father is feeling better!
Thank you for the info. I was looking for an tutorial, lol. I thought this was something new/updated method. I've known this but thought it was for a different application other than cannabis concentrated oil. The reason why I have never tried this method (IMHO) is through the complete process of making the concentrated oil the only time I leave any stage unattended is when the rice cooker is first plugged in with the solvent/extracts poured inside. Just to clear some of the equipment that is no longer needed out of the way. When the decarbing begins I pay close attention from the start to the finish. Paying closer attention if using the double boiler method. If I want the oil to be peak THC I would remove the oil cup from the hot oil bath when the bubbles are big. If looking for more CBD & CBN to develop mid to smaller bubbles. If I want full couch lock wait until the bubbles stop completely. It all depends on what condition I'm making the medicine for. Cancer, PTSD/depression, anxiety/panic attacks, chronic pain, the list goes on. I am explaining this in a little more detail to answer both questions at once. Cancer as a primary example; I would remove the oil (after any carrier is burned off) right after the bubbles are big. Then I would make a high CBD strain of concentrate and when going through the decarbing process (double boiler) I would remove the oil cup when the bubbles have completely stopped for max cbd, cbn for shrinking any tumors and removing any inflammation. So as an example two strains for cancer two different decarbing processes. I would like to mention the double boiler decarbing process only takes from 15-30 minutes depending on the ambient temperature inside (cold/hot). The process sometimes is quicker or shorter, I do not see that kind of control using the oven decarbing method. Also an honorable mention is 'out of sight-out of mind' in the oven (especially if the person with cancer doesn't have someone else to help, is tired and naps). Then when removing the oil cup from the oven you accidently touch a hot rack and spill. You mentioned that you thought it would be unsafe using the double boiler method? If you have a large washer in the oil bath pan and a long handle on the oil cup it is very easily controlled. Especially with a tight fitting hot pad glove.
This is an advantage also using food grade carriers. If you remove the oil cup right after 'big bubbles' for max thc content are you completely sure if using naphtha light all the chems are removed? In my opinion you would have to do a vacuum purge to make sure. With food grade carrier like ethanol/grain alcohol you could simply put it on something right around 110 degrees and have a fan on low blowing a breeze over the cup (slightly pointing up) for 20 minutes or until its dissipated/evaporated. Knowing its safe if consumed.
Only insight I have is what I've learned from trusted sites. You have read them also. Best word of advice I have is practice different techniques and judge for yourself. Doing this you will be able to see for yourself to gain the knowledge you seek. You will find out it seems there is never concise information, practice will show you this. People have different opinions and methods. Have you checked out skunk pharms decarbing process? Read it to the end and it explains pretty much what I have said. It has all the charts, etc.
I hope I have clarified some things. Why I do not prefer the oven decarbing method. That being said whatever choice you decide is what is best for you. Only experience will give you 'true' answers.
BTW did you get your Dad some high cbd strain? Shrinking the tumors and removing any inflammation in the brain has a huge healing factor with the OG Kush oil you have. Is he taking the concentrate correctly? No euphoric? Give him my best regards please.

Thank you for the information and your thoughts about my dad. It is very much appreciated.
Dad is now taking the oil per your instructions and feeling much better. I think the dentures were a huge problem too because he didn't remove them and we suspect that some of the "aftertaste" he was complaining about was probably the result of the oil not fully being absorbed but maybe remaining on the dentures. This may explain his nausea too as that has now stopped.
It is not so easy for us to get different strains so we purchased online some CBD hemp oil. Do you think that has any value? Should we give it to him? If so, when...at the same time, alternating doses, some other method?
