Help. Want to oxidize THC to CBN

I want to make low THC high CBN concentrate.

I let my high THC Indica hybrids mature as long as possible before mold started to show up. (10 to20% Amber trics)

Dried and cured as normal dark conditions, to stem snap, burping jars after that.

----
So I took and tossed about 1/2 lb of trim and less than perfect bud into a clear open Tupperware tote and stuck it in the sunny greenhouse.

I plan to double decarb in my Nova lift, and stick it back in the sun.

Any other ideas? Basically looking for minimal THC and maximum CBN.
(I can always add CBD to cut any THC high left)

are there popular cbn bred plants like there thc/v & cbd bred ones? can a clear/cloudy resin gland possess high levels of cbn? using uvb on the plants i think would make them age faster/deteriorate quicker while growing. can you decarb longer than normal to convert thc thc to cbn faster?

sorry for all the questions

Just wondering why you are looking for cbn?
Is it what cause's the sleepy, couch lock effect?
Is that what your looking for?

YES
CNB is a seditive, said to be stronger than Diazepam. Looking for the narcotic seditive effect without the THC high. I personally dislike THC head high. Put up with it to get couch lock after the buzz wears off.

If I wouldn't end up dead, I I would just take Diazepam, drink whiskey and smoke opium.

I got CBD concentrate down pat.

Now need to figure out how to degrade THC to CBN

I remember reading you have to decarb the material over span of almost a week to get significant cbn. It takes a while. Are you able to have your material tested afterwards to determine the final ratios of cannabinoids?

look for a lot of small red/brown trichs. that's about the only way to know you're getting a good percentage of cbn that i'm aware of, without a chemical test

Yep figure I am the human lab test. The more sedated and the less stoned the more CBN.. LOL.

Let the plants go as long as possible usually some amber trichs. Powdery mildew and mold are a real problem in my short dark damp PNW marine climate, even in the greenhouse. Growing season. Just simply ends mid September.

Want even higher CBN.

Been reading on some of the modern isolate makers oxidizing high .THC strains by decarbing for 72 hours, to convert THC to CBN.?

So I'm not sure if this is what you're looking for, but it might help.

I believe that when you expose THC to UV it degrades into CBN.

I know that if you do an alcohol extraction and expose the extraction to sunlight for some hours it will turn bright red, and I'm under the impression that this degrades the THC in the same way.

I'm also under the impression that being dissolved in the alcohol is what expediates this process.

Sadly I don't have test results on any of this. Its based on reading and research I did years ago. I have done this process and witnessed the results but can't really speak to the true effect with out test results.

Interesting!
Never heard the alcohol extract expedites the process.

Cool
I can try that. I can decarb as normal, make concentrate and pour the concetrate onto a plate of glass and stick it in a warm sunny spot, let it dry into shatter and oxidize. (Hopefully)

Way better than trying to oxidize a pile of mid quality herb in the open with critters trying to nest in it.

I would love to see how this turns out for you, especially if you have a way to have the concentrate tested. It would be really interesting to see a test of before and after. Perhaps saving part of the liquid and evaping normally then having both versions tested?

I can keep a "before" sample to compare. I will test on my self and if I feel a difference, between the two... If so that would warrant lab testing.

(Stoner science thinks it should work as a thin film of concentrate will be more exposed to 02 and UV.)

I'll keep the box of buds in the open air and exposed to light until I get around to decarb and concentrating.

I've never decarbed before making a concentrate, I wonder how that would effect the process. I'm curious which is easier to convert to cbn THC or THCa.

We need some of the resident RIU chemistry specialists to weigh in here.

@qwisoking do you know how the UV degradation on alcohol extracts works?

More questions!

Does CBD oxidize at the same rate as THC.?

Thought being one has the typical 1:1 or
1 THC: 2 CBD strain.

Could one oxidize it and convert the THC to CBN while retaining the CBD?

That be a nice med. CBD and CBN

should work....don't see why it wouldn't. i'd go with the minimum temps if you're going for 72 hours, at least the first time, and see what kind of results you get

You can let the plant sit and flower a full week longer than you usually would and you still will not produce significant cbn. I have fully decarbed my material in the past, all the thca was gone and there was thc in the sample and hardly any cbn. Again, try decarbing your material over span of a week. For example, toss it in the oven for eight hours a day at 240f, for 7 days.

Edit: instead of 240f , i would do 200f for 40-50 hours with freshly dried material. Just try a small amount, and see how it goes. I also remember someone finding significant cbn in the sample, after only 3-4 hours of decarb at 240f, but the material was already couple years old. So in conclusion, play around with different durations, and like you said, go by how you feel.
