The dreckos will live on the walls and ceiling primarily, basking in the hydrogen and growing scales.
Thus, the room produced electricity, O2, and remains half full of hydrogen.įarm tiles on the floor - one per drecko is fine, maybe an extra or two to account for any issues - growing mealwood.
Hydrogen pools at the roof (which obviously has no vents!) and once it fills half the room, it turns the gas pump on and sends hydrogen out to a hydrogen generator or wherever else you want to use it. O2 leaves the room via vents on the floor/standard doors, helping to oxygenate your base. The electrolizer produces O2 and Hydrogen. Set the gas sensor to hydrogen, and you're golden. I don't have that save anymore, but I did set it up thus: Largish room around 8 tiles high, with a electolizer, a gas pump close to the ceiling, and a gas sensor half way up the room. That space heater is an ugly temporary solution to the problem. Balm lilies also need higher temperature so I shouldn't have built mine in the same stack. Without this, CO2 will creep in and stunt the plants since they need chlorine. The balm lily version has a CO2 trap as well with a mini-pump. The grooming chamber is open to the rest of the base with a pneumatic door so it gets oxygen, but the narrow ladder generally keeps the oxygen from penetrating the main chamber if you have enough pressure. This does cost you on the back end for grooming time, a bit. The room is designed to be circuitous in the hydrogen area so the animals spend more time there. The basic idea is to lay down a tile or two of carbon dioxide (for mealwood or bristleberry) or chlorine (for balm lily), then a bunch of hydrogen for scale growth. The pump is activated by a player-interactive clock sensor whenever you need to flush some oxygen that snuck in.
I tend to use a gas canister emptier now to add gas (more controllable), and I have a system in each ranch to selectively vent gases that find their way in. The ranch has 12 plants, which is enough for 4 glossy dreckos or 6 (?) standard ones. As a result, it'll probably need some maintenance every once in a while, but not terribly often. I don't like liquid locks and I reserve atmo suits for space and oil, generally, so this ranch is designed without those "crutches". Lots of ranches are super-finicky about gas separation so use waterlocks or atmo suits or something. Started with mealwood to up the egg-laying chances and swapped to bristleberry: I'm at cycle 120ish and build my first of these 3 around cycle 30-50. This is my usual drecko ranch, designed for early / midgame.
