Decarb.
If one were to say, hook up a thermocouple to the Nova, one would see it spend 15 min getting up to 240f. Then, it holds 240f almost exactly for one hour. Then it spends 15 min cooling off. We achieved a 98.2% decarb with virtually no CBN. (test showed 0.06% after decarb but that mysteriously cured itself in subsequent tests.) The Nova is a well controlled environment. A must have? Well I just told you how to duplicate the results. However, I like it for the set it & forget it feature. Also, good smell control. That's a biggie for the bulk of the world.
Do it any way you want. Just tightly control that temp. YES, before everybody chimes in, there are lots of other time/temp values that will work. Just remember, it's a first order reaction all day long so the time/temp are always going to be inversely related. But this is a proven time/temp to use as a baseline.
Do I recommend the Nova? Before I answer, I am not compensated in any way. Hell, they won't even answer emails. IF it continues to run trouble free for a few years, then yes, it is worth it to me. If it burns out in 9 months, I will be making my own. (it has a 1 yr warranty but you get the idea)
I'm not saying stop experimenting by any means! This is simply a proven way to get it done. Canyon and others are experimenting with pressure for terpene retention. There's plenty of room for refinement. Remember, this plant is used in a lot of ways. Decarbing under pressure or in a vacuum is worth looking at. So, now you know what I know about that.
