Here is the problem. Most strains that are high in CBD are not what you would consider high in CBD.
I went to my local dispensary and got cannatonic. It is the highest strain I could locate.
[TAC: 22.5%] THCA: 0.6%, THC: 0.1%, CBGA: 0.5%, CBD: 0.6%, CBDV: 1.1%, CBDA: 19.6%
So those numbers are verified with laboratory testing. But the reality is that is you order 4 seeds of cannatonic, because of the different phenotypes you could wind up with four different phenotypes.
HIGH CBD LOW THC
HIGH THC LOW CBD
Medium high THC and medium low CBD
Medium high CBD and medium low THC
You would have to grow the four plants and submit all four from testing to determine which have the high (or higher CBD) and which ones don’t.
I also live in a free state and this is something I have been investigating for nearly a year. Unfortunately it isn’t as easy as some folks would have you believe!
Now with all that being said, THC is not active when absorbed through the skin. So in theory if your making salve then any strain rated as a high CBD should be good enough.
For me and my wife, I buy pure CBD oil rated at 250mg per 30ml. I know exactly what I have got and exactly what to use.

Have a look through that list and see if any of those appeal to you and we can talk about them. Narrow the list to two or three and we can go from there! @MacGuyverMedic
