Seems good to me too . However , perhaps instead of genocide it takes a measure of ' justice ' against the precursors instead ? Instead of the armies of terminators it engineers the precursors to fight themselves , perhaps starting a civil war . Maybe the precursors were still quite powerful and unified to withstand a robotic apocalypse that would take months to build up and perhaps give plenty of warning . If it was building up the armies for both or more sides then a sudden betrayal to wipe them all out would be very effective . Then it enslaves the rest of the race , perhaps a secret from the rest of the galaxy . They live in comfort but it delights in them as playthings . <| sep |> You must have had it set up correctly or had a real shitty one . Phresh filters are fucking great , and I ' m telling you that you won ' t need more than one for a 1 kilo or less grow if set up properly .
