THC to CBN

Discussion in 'Weed Edibles' started by Nematode128, Feb 10, 2021.

  1. It's my understanding that you can basically convert thc to cbn at home by doing a super long decarb (couple hours vs the typical 40 mins at 240°) but what's the actual conversion rate of thc to cbn? I know if I have a gram of flower that's testing at 20% thc that it will give me approx 200mg thc after a 40 min decarb but how much of that 200mg will actually convert into cbn?

  2. Good question, unfortunately I don't have an answer, lol.

    I have tried a double decarb, 2 cycles, in my nova fx to make cbn. It seemed to have worked but the herb became pretty weak although it was yawn inducing. I suspect I destroyed a lot of cannabinoids in the process. I saved it by using that oil for another infusion and that works really well. But I used a lot of herb, so it wasn't economical.

    So I know doubling the decarb time isn't ideal. Adding to the total decarb time is probably helpful but I don't know an ideal time.

    On my nova fx it has a cbd decarb setting. I've read it's the same temp as the thc setting but it goes longer. I'll try that at some point.

    I did ask ardent, Nova's manufacturer about this and they said, in so many words, go for it, with no commitment to any outcome.

    Temperature wise I've read 300°F will turn thc into cbd, but I haven't tried that. Or have any idea of a time frame at that temperature.

    I think it's going to be tricky to find a good way to get cbn without destroying most of the thc or cbd's.
