3) Condensates Production set up set up for 24 or 5 hour cycles. (handles both equaly well). Oxygen is imported to the planet. I could produce oxygen on the planet but because of the size of gas giant planets, the links would have consumed a LOT of the PG available from the command center. As a result, i clustered the entire colony to reduce the link PG use. 20 structures on a gas giant with command center 4 as a result Pretty happy with this colony setup.
