I’ve heard you say it a couple times now, you’re wrong about there being a penalty to mining oxylite. Natural oxylite tiles off gas at 50%. Yes, if you dig the tile the debris will be half the mass of the tile, but debris off gasses at 100%. So whether you dig it up or leave it in place, you will only ever get 50% of the mass of an oxylite tile off gassed as oxygen gas.

2024 came by and said hello to you all! Thank you for all the great content, have watched it many times.

i build one, maybe two bases a year, then i go to other games. But a always return ; to ONI and to your channel. 🙂 See you in 2025 and all the best to the community! 🐱

Now just waiting for the Not and the Included tutorials so I can finish my Oxygen Not Included base 🙏

Really, you deserve an Oscar for this! I finally understand that Rodriguez thing. And it worked! I just made it and it worked! I can't believe it! A small space for such a good production of oxygen. Amazing. I reduced the space for oxygen production by 70%. I used so much space on my layout it's even shameful! Thank you so much for explaining this as simply as you did for us mere mortals. LOL! Great job! Klei MUST hire you!

I really appreciate your one-stop shopping images for the full builds. They're nicely laid out and helpful for reference as I get back into the game.

I had a stackable version of the full Rodriguez... but it wasn't as tightly built. I like that better.

Two tips about the spom. First, if your water source is cool enough you can snake radiant pipes around the oxygen pumps at the bottom to keep the oxygen cooler.

Second, when you are first starting up the spom (and dealing with the mixture of gases), it is much easier to just create and off shoot pipe from the one top hydrogen pump and pump everything out (some hydrogen will get out with everything else). Then, once all the other gases have cleared out and the oxygen and hydrogen pressures have become stable, then connect the hydrogen pump up to the hydrogen generators. It is similar to what you said in the video, but this way you do not have to repair the hydrogen generators, and you can create a fully enclosed spom and never have to break it open.

Built the half Rodriguez and it worked like a charm. Thanks🙂

[axixmu]

this is such a useful tutorial, been following your tutorials for sometime and they really improved my dups lives! Thank you so much!

I have personally gotten a lot of use from the algae terrariums. Once you have a sieve, they use very little water, eliminate a tiny amount of co2, and can produce a good supply of oxygen. Just don't lock them in airtight areas, they will not stop producing regardless of pressure, so I had one chamber that popped the eardrums of every dupe in the base when someone opened that door with 24kg per tile of oxygen on the other side.

They are also best used with lights for even more oxygen.

Are they ideal? Probably not. But they are useful in the right circumstances.

Thank you so much for the SPOM design (:

[callummcneill]

Thank you! I have been wondering how to build a Rodriguez properly

[mrdrissou_]

You need to be an engineer to play this game 😅
Thanks for tips 👍

Pdirt form arbor trees are also a good option for sustainable oxygen production. I realize that this video is a year old and that back then we had fewer ways to sustainable get filtration medium, but even without filtration medium, you can clean polluted oxygen by cooling it down into a liquid and then heating it back up.

[VadimBolshakov]

My 2 cents: 1) I usually add hydrogen loop for hydrogens, and route excess hydrogen to separate grid. This makes sure oxygen is always powered and you consume all excess hydrogen without waste. 2) I never built OR gate in this game as you can simply merge the wires directly and it will work the same ...

[frankyanish]

I don’t know if anybody else has mentioned this, but the mouth breather trait at the beginning is listed as taking triple the oxygen.

[atellismarin]

did something similar to control excess hydrogen, but I used a gas element sensor in the vent pipe and a filter to delay it turning on for 5 seconds. I placed the sensor 3 tiles away from the pump to maximize the hydrogen stored in the pipes. Gives a little extra time incase something goes wrong. Also I tend to disconnect it completely just because the build running on its own amuses me

Ive played this game for years and i keep coming to CG the OGFungus 😀

Hey, I just started playing ONI again after I failed like 5 colonies back in 2019. I found your channel really really helpful and enjoy watching every tutorial even when already knowing about it or not planning to build it because they are so informative. But one thing struck my mind with all the 6 oxygen pumps designs:

Wouldn't these designs get inefficient at some point since they produce 4x888mg/s oxygen (3552) but are only able to pump 3000mg/s out, resulting in overpressure for the electrolyzers. Is it better to build 8 oxygen pumps (7.1 needed technically) or would this just be overkill?
Also do I need to build a seperate ventilation line for each pair of pumps? I haven't found a way yet to merge these pumps together without the oxygen jamming at some point in time.

[jaredboudreaux]

I agree with everything except the slickster thing... i ALWAYS pump my co2 into my oil biome with my slickster babies they eat it up and give free oil! it's so much better than spacing or washing it!

6:03 simply using vents to distribute oxygen is NOT a sure method. It relies on you having only oxygen in any area where you have a vent. Otherwise a small packet of some other gas (say polluted oxygen for example) can cover the vent temporarily and allow the oxygen out. This is fine in small cases especially where you are not significantly overproducing oxygen, but can easily lead to massive overpressuring if left for a long term over multiple rooms and with excess O2 production.

Making sure your vents are always at the top of rooms helps. The only gas in the game later than Oxygen is Hydrogen, and as long as your electrolyzer is filtered properly it's unlikely you will have hydrogen leaking into your base consistently. Removing hydrogen is as easy as ventilating the top of your base as well, although that can cause problems with Polluted Oxygen, which is the most likely culprit in the long run for gas over-pressurization.

If you are unable to keep your base clear of Hydrogen and Polluted Oxygen, you'll need to add automation to your vents. You'll want an atmo sensor and a filter gate for each vent. The filter gate will see that there has been a low pressure packet over the atmo sensor for several consecutive seconds, allowing a green signal through to release the O2 (sensor is set low=green)
