I've been to the vendors that the wiki said had them, but they just don't for some reason. What am i doing wrong?

First time player, no tutorials or help yet. Feel very stuck, any tips? also please dont judge lol.

Can't seem to get any bright green, do i just build more centrifuges? that feels wrong lol.
