CBD to CBN without a lab

,

Is it possible to take CBD distillate and degrade it on a hot stir plate to convert it to CBN?

If not, is it possible in a reasonable amount of time without chemistry equipment?

You can get about 30% yield through this method

What does it turn into if I increase the temp significantly for an extended period of time. I’d assume it all would get converted to something else, no?

Yes, but as far as i know nobody has determined what exactly the rest is turning into.
