Sheriffanswered grow question 2 years ago Before my answer:
Indica/Sativa/Afganica etc is more about marketing cause breeders are mixing that a lot so you're not able to clear out what exactly it is. Remember 70's, when strains was mixed randomly. It was even reminded in Jorge Cervantes book.
From medical perspective your decision is max CBD, low or almost zero THC, so I don't agree with Do-Si-Dos, Pineapple Express and so on.
CBD Auto 20:1 or something like that would be fine.
I strongly suggest you to avoid high THC-strains to person with active PTSD
