My pufts always starve.

[Devs]

I like messing with puft farms, but I can do pretty much anything and they still end up hungry/starving. I had one successful attempt, so added a new one, and then they both went hungry. I then hunted the spare one, and the survivor is still hungry. There was P-water in the cage, and I had a vent to pump out unwanted gases, and I even had a subliminator and a device which released P-water. Getting frustrating. What else could I try? THNX.

I've only done one successful puft farm but I would say to keep in mind that they "eat" a lot of gas.

Perhaps your polluted oxygen pressure is too low. AKA, the air is too thin.

[Devs]

Never had issues with grilling pufts (yet). The air is definitely too thin as the pufts typically run the sources dry. Still, what else makes P-oxygen, and not just P-water?

[Ender's games]

Polluted water is the solution, if you ask me, but you need to consider a few things, just to be safe.
1. Have enough polluted water.
2. Don't have high pressure of other gasses (specially CO2). This will set up right above the water and prevent it from giving polluted oxygen.
3. How many pufts can your polluted water/polluted oxygen sustain?
4. Is the polluted oxygen going somewhere else?

[Devs]

The P-oxygen was bursting outside of the pen, so I grabbed another puft- thus the setup failed. As for the P-water, my dupe made a mess in the puft pen, and as it was for pufts, I just left it there. I'll probably make a toilet that just releases its stuff in there eventually. I ended up restarting since then, but the setup for the next puft pen should be roughly the same this time around. I have a mod that has a device which releases P-oxygen while it converts P-water into clean water, and I pump out any gases that aren't the P-oxygen. With this setup, I guess I can only have one puft, which isn't very useful for collecting slime. After getting the second one, I added the subliminator, which didn't really help.

Theory... I might be able to make the next pen by going to a place infested with slimelung, P-water, and and a wild puft, and just plant a stable there and slowly block off the area with tiles to fit the stable maximum space count. Unsure if that area will get drained of P-water and P-oxygen, though. I had one successful farm that way, but I'd rather find a way to do it so my character(s) won't have to take a long trek to get to the pen and back to the base.

1. Can you post a screen shot of your "Pen"
2. You could also put a a storage box in the room and fill it with polluted dirt to help off gas.
3. Why do you need slime?

[intenselygoodtime]

If there was a wide pool of p-water at the bottom of the room generating p-oxygen, you could build a simple air filtering system (say, one battery and one hamster wheel), where the intake vent is the center tile just above the p-water, and the output vent is at the top of the room. Only dump p-oxygen back into the room, and everything else vents outside. It'll only run when the room is NOT at full pressure.

Now that I'm thinking about it, I don't think I've had more than 2-3 pufts at a time either, but I do know that I've never pumped outside p-oxygen into their rooms. Typically just carve whatever p-water bowl existed wherever I found them, such that slime excretions would only ever fall into p-water below, never on a solid dry surface.

Wide pools are... less than ideal.

Build a reservoir, pump it full of p-water, then deconstruct it. You'll be left with all of that p-water in a bottle... which off-gasses much faster. Leave the pipes in place; if/when you need more p-oxygen, just rebuild the reservoir and do it again.

I actually like this idea! I'll have to come around a puft or two and try it out. I wonder if I could also just dump them in a room full of those algae plants and leave the P-water down there? Get rid of the CO2 as well.

Algae terrariums eat CO2, but they also produce clean oxygen. Ideally, you want your puft ranch to be nothing but p-O2.

CO2 is heavier than O2 or p-O2, so just put a carbon skimmer and a water sieve in a loop at the lowest point in the area to handle it.

That is, run a pipe from the skimmer's output to the sieve's input, fill that with p-water, disconnect the bridge used to fill it, then run the pipe from the sieve's output to the skimmer's input. It will run forever from that point on, needing only power and sand.

[Myriad]

Quite a simple approach, but I usually just dig into a confined slime biome if I want to store a few Pufts. Partially clear it out, leaving the p-water at the bottom and some slime around. And I find they thrive well enough.

Never tested it with bottles. But since one tile offgases quite a bit even in vaccum, Maybe we can create a vacuum chamber over the polluted water pool with a small pump and turn it basicaly into P Oxygen production machine this way? If there is no overpressurising we should get 20-30 Kg per tile right?

If you really want to produce a ton of p-O2, I saw some guy in a YouTube video pumping it into a single layer of empty tiles, completely surrounded by airflow tiles. It can then offgas in every direction (which is why pools don't work so well; the liquid (or solid tiles) below and on either side eliminates 75% of the liquid's surface area). As it offgases, the pump pushes more into the space, so it's always at maximum pressure... which means it's constantly trying to make the air around it be at the same pressure as itself; ie, 100kg per tile.

He had a bunch of deodorizers turning it into "clean" O2, but there's no reason it wouldn't work just as well for keeping pufts fat and sassy.

[XceptOne]

Did you try this yourself?
I mean the offgassing in all directions thing. To me it seemed like p-water will only ever offgas to the top, even when completely surrounded by low pressure po2 (I have built things like this).
(The 'new-ish' (introduced with dlc) polluted dirt and polluted mud tiles will offgas in any direction)

Otherwise that build works nicely as offgassing polluted water is proportional to its' mass (haven't tried the infinite storage scenario, yet), but the gas pressure limit is still 1800g, so...

...this is just wrong.


Edit: you can have singular low pressure co2 (chlorine, anything heavier than po2) tiles roaming around the lakes surface to trick pressure checks. That's what happens in highly pressurized slime biomes.

Edit2: What I've never tested (thanks for sparking that idea), maybe p-water can offgas in all direcetions, but not a tile in multiple directions at once. So maybe I test with two layers of p-water (on airflow tiles).
Edit3: Though, my expected result would be the lower layer being completely inert. (Maybe I did test that at some point)

Algae terrariums will happily pressurize their environment to 20 kg/tile, if you let them; there is no actual limit to gas pressure, you're thinking of vents and algae deoxydizers. Also, you missed the part where there are deodorizers turning all the p-O2 into "clean" O2 as fast as it's produced, so it will actually pressurize the local region to ridiculous levels... again, if you let it.

You're right, though, I shouldn't post before I've had my coffee... I explained that very badly.

[XceptOne]

No, I was thinkling of polluted water. I missed the bottles, though.
