The cultivation info here is not specific to P. yoco, but my guess is that it might be similar to guarana... sounds like low pH might help, and says maybe take up to 100 days, so dont gets be up on them!
https://hort.purdue.edu/newcrop/1492/paullinia.htmlThere’s also this study, not remarkebly exciting info, but it’s data on several interesting species, including P. rugosa, which I’d assume would require similar germination conditions. Basically all it says though is don’t let those seeds dry out. Grown at 25C, 12hr light sched. Or that’s all I gathered from my quick skim.

Idk about kola, sorry, if I find any good info I’ll be sure to share.
