do you not understand the relevance of THCv?
(https://www.caymanchem.com/news/why-does-alkyl-chain-length-matter)
Or currently available genetics?
See maybe: CBDP and THCP?
Is it possible to make from cannabis
no. It cannot be “washed out” with current genetics.
is anyone making THCp in the CA L2L market?
No. one cannot change the length of the alkane tail on THC after it has been synthesized (by the plant), so one has to make it from scratch. the CA market does not allow synthetics.

the trick (biologically speaking) is to feed OAC a shorter or longer tetra-ketide (the TKS step) to the cyclase (OAC, although it won’t be Olivetolic Acid it is performing it’s ring closing magic upon).
