AZS, I think the last two pics are tacaquirensis... the first pic, "werdemanianus" could also be some form of taquimbalensis... beautiful specimens everyone
It looks like T.glaucus or any of these "species" names that refer to a more tubercloid, sometimes with reddish spines macro/peruv types. Nice specimen!

Fresh seeds have a pretty good germination rate without cold stratification.
This is a year-old seedling , its so small due to the shallowness of the tray it was sown
