Oxygen deletion in glossy drecko farm

[CakeEater]

I keep filling in the bottom of my glossy drecko farm with oxygen via manual gas bottle emptier to keep the mealwood growing, but the oxygen keeps disappearing.

Can someone tell me what's going on here? Is my water lock somehow to blame? At first I thought it was my door opening and closing, so I moved it to the other side of the water lock but the oxygen is still disappearing.

Well, dupes do turn oxygen into Co2 over time. I would very much recommend using a pump with a filter and a high pressure vent to get the O2 inside, and exosuits to prevent the dupes from actually breathing the O2 in the ranch. I prefer this because dupes without suits will inevitably be miserable in a drecko ranch anyway, since the O2 in it won't last. They'll get wet and have to hold their breath in both the CO2 and hydrogen inside. Simpler to just give them suits. Once the ranch is done you just need maybe two suits anyway, so no biggie to keep them topped off. The water lock is OK, except that the dreckos can pass it, as I deduce by your multiple doors that you have noticed. If you make a 3x2 lock and fill it though they can not pass that, and you can keep a single door open without risk of escape.

Something like this, except with oxygen. And no space heater. I usually pressurize around 1.5-2K for hydrogen first and then push in the other gas until the cage is at about 3-4k. Depends when the level gets to where I want it.

The reason I pump in hydrogen first is that a few times when I have done it the other way around it has taken a very long time to get the O2/chlorine level down to where I want it with H coming in at the top. It tends to accumulate in the top and then Abruptly all whoosh down at long last. If the level is fine then, all is well. but once it wasn't, and I had to spend another half hour pumping in more O2 to get the level up. Maybe it doesn't matter and I'm just clumsy though. It's always possible...

I thought it might be dupes breathing it in, but I never noticed any CO2 in the ranch with them. All the oxygen just disappeared and got dominated by hydrogen. My screen shot as it is now is a good example of this.

To your water lock point, I kept it minimal so my dupes only got the soggy feet debuff, and not the sopping wet one.

Yes I figured that. But at least for me the problem with this ranch in particular has always been exhaling Co2 over time. I'm sure you could design a ranch that lets out Co2 and keeps the O2 level steady, but I'm not sure how. This and the wetness debiffs is why I decided on exosuits for drecko ranches. It solves both problems, plus you can have a more filled lock to keep them inside the ranch at all times.

here is my setup : (you dont need water)

See, i tried to build them like this at first too, but the hydrogen exposure becomes a problem when you have an entire "basement" just to get rid of Co2.

Is not that bad but if you like you can change the floor to air flow tile and have the base pressure handle the level, thats why I add a pump and a tank to set the correct pressure

Wiki says dupes breathe in 100g/s oxygen but produce 2g/s CO2. So yeah, they reduce your gas by 98%. You could just fill the room with CO2 and have them hold their breath until you have suits.

I have no problems with people having different philosophies and solutions. Just stating my experience with more open solutions, which are why I have landed on suits-only for drecko ranches. With suits I can completely seal the ranch and keep a fixed atmo in place that never changes, and without the need for an overflow Co2 system or somehow replenishing the O2 that gets inhaled by the dupes. And I can use drecko proof water locks too without constantly debuffing the dupes, who now also do not need to hold their breath in various noxious gases while tending to the critters. To me it's just better, full stop. And by enough that I always rush the suit/crusher/ranching techs to get drecko ranches up and running as soon as it's practical.

The only remaining problem for me is squeezing in automation into the smaller, hermetically sealed ranches. Manually they become quite labor intensive. But this is a smaller problem I think than constant soggy feet debuffs and the morale effects of not being able to breathe.

Skull you are right and yes you can close the room but hydrogen will go up if you have more pressure below with O2 or CO2

so why close it or use water if you can just add something to keep up the pressure, I have my setup inside the main base so the pressure of the O2 will be strong to keep any hydrogen on the top of the room

Because it fluctuates, particularly early on when you're working on the O2 system. I am not even slightly interested in having a moving hydrogen line in my drecko ranches. I want to set it at the level I think is best, pressurize the room and not have to think about it again. Plenty of other things to micro manage in this game without adding more when you don't have to. That's why you close it.

Sure, like you say before "different philosophies and solutions"

Well if you already have a problem on keeping the pressure on the main base them I can see why you say is hard.

You dont need more micro manage, you already need to have on the main base a way to control pressure, or do like many and add gas vents, turn on and forget.

The gas vent go a max of 1800g and dups get the debuf after 2000g, if you add 1000g or 1kg of
hydrogen the O2 pressure will kep the hydrogen on top of any room.

If you have any fluctuation is in the range of 100g to 200g, I dont see how this is a problem.
