Yes they are selling GBG isolate oddly enough. the problem being CBG alone, and/or any isolated cannabinoid is the lack of synergistic interaction of different cannabinoids together that has real effect. I suppose you could use the isolate to boost the CBG content of your extract by mixing it in.
I feel bad for all these companies that spent big money on all this expensive lab equipment to make isolates, only to find out that their "pure" CBD is next to useless alone are next to nothing compared to homemade tincture. Maybe CBN will bring new use to tech that is about to be sitting around collecting dust.
I wonder what the options will be when they offer a CBN without thc product. Obviously it would probably start with an Isolate. hopefully premixed with a nice CBD full plant extract so that it will work properly.
What I would like to see though, is a full plant extract from a high CBN/low thc plant/strain. I am no breeder but that sounds like quite a breeding project. I'd love to see someone pull that off!

What state. ??
I have not seen any isolates in WA. Then again I have not been in a store in over a year.. lol
--
For me my home made high CBD concentrates, (Charlotte Angel auto) are leaps and bounds more effective than purchased CO2 CBD isolate from Colorado.
IMO the value of isolate is the ability to recombine in a formula specific to the individual.
This is the fail of big Pharma.
Full spectrum is where it's at..
Don't know about breeding a high CBN weed. To me it seems to be the handling of a hash plant Indica that increases CBN.
Air dry in the sun, heat press dry sift. Store hot for a long time.
I think most CBN is from oxidized THC.

My thoughts exactly. This is why I said it would be quite the breeding project. No in plant synthase for it.
The CBG isolate is available online all over. one example: https://discovercbd.com/products/cbg-isolate-98?variant=43730863756
Edit: my img won't show up. ill try and fix. it might be helpful

You know that's a good question. I had assumed that was part of it. I was also under the impression it broke down chlorophyll as well an that was part of the color change.
This makes me want to experiment on my next batch. I've put green c grade washes in the sun before for fun and try turned red, and seemed to be smoother. I have never put a clean A grade wash in the sun to see what happened. It might be neat though. It also makes me want to get a UV light to expose the solution indoors in a more controlled manner. Do we know if it's uva or uvb to does the conversion or if it matters?

If you use reptile or UV grow bulbs you'll cover both anyway.
I don't honestly know which is required but during grows where I've played with UV UVb gives faster results (I wanna say better but that's subjective)
If I were to try this I'd personally use vacuum assisted drying and collect the terps that gas off there and then vacuum distillation to try separate the cannabinoids from terps so I'd have a better idea what's going on.
Id also know terps weren't being negatively affected.
I dunno if it's true but I've been told terps have medicinal value too?
Lastly, I know you might not have the equipment to go the route I would and I don't blame you for not buying them for one off experiments, after all wiped film distillation would probably give better cannabinoid separation but I ain't shelling out for a unit in a hurry lol

Hehe nope I can't do all that, but I find it very interesting and I you can do it I'd love to hear the results 
. This stuff is fascinating, I love hearing from you guys with options and knowledge to dig deeper.

This is a really cool thread, and idea. Since I am the new owner of a rosin press I am wondering what would happen if I put my rosin under a UV light for a while? Likely I would get some CBN and CBNa conversion. How would one determine the length of exposure time necessary under the light I wonder. Pressing the bud @ 220f is going to convert some of the THCa to THC, but there is probably alot of THCa still in the rosin along with all kinds of other cannabinoids .

Wow
Never considered. UV only without decarb would make THCA to CBNA.
My first batch I Decarbed hard and heavy, prior to the knowledge of UV.
I assume UV does not ditch the "A"???
Anyone know for sure?

I haven't found much on UV degrading cannabis but have found a table taken from the article linked showing temperature based degradation.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2921171/
Ive no idea how folks get full size pictures, mines always show as thumbnails but I've attached the table.
Feel free to read through the link but the biggest takeaway is the table lol
THC DEGRADATION OVER 90 MINUTES OF EXPOSURE
Every study I've read thus far also hae two general points of note
1. Nobody gives a fuck about UV lol, the studies for the most part cover artifical lighting like fluorescents etc and sunlight.
2. Initial degradation occurs quite quickly (in relative terms, see table above)
I hope the above is somewhat helpful to someone lol.
A thing I'd like to point out about UV is that typically short wavelength UV like UVb (280-300nm) is classed as an oxidiser, UVa close to the UVb threshold also act like oxidisers.
Has anyone any thoughts about use of heat, UV (say an agromax bulb) and an oxidiser such as H²O² ?
All commonly available or easy to cobble solutions tbh
Edited to add:
Holy fuck, the tables where it should be

So, the only study focusing on UV I've found is
"The Stability of cannabis and its preparations on storage" (1976) by J.W. Fairbairn, J.A. Liebmann and M.G. Rowan
Theres very little else although a metric fuck load of other studies reference this.
The takeaway from that study as far as I can tell is that UV kills cannabinoids and doesn't just degrade them to CBN?
Quote from the study
"Loss of tetrahydrocannabinol after exposure to light does not lead to an increase in cannabinol, but air oxidation in the dark does."
Hmmm
