Why does oxyfern suck?

[cyboogie king]

It's a good concept but they eat up water too quickly, which is a rarity in the starting biome they are found it. Plus you need like 12 to sustain 4 duplicants, and I only found 14 across the whole biome. You have to scatter them everywhere otherwise there will only be oxygen in one area, but they need to be in a carbon-dioxide-rich enviroment. I had 7 dupes so the oxygen was becoming a problem. I decided to try out to replace them with 3 rust deoxiders and oxygen was no longer a problem. These plants are basically useless after 15 cycles. Too bad you can't reproduce them or anything.

They return more o2 per kg water than electrolyzers. Does not require power, and does not heat it to 70°. Yes you are limited in how many you can plant. That doesn't make the ones you can plant bad. Pretty strong stats imo.

Would choose electrolyzers over that any day. Unlike oxyferns, I'm not limited on where I can place my electrolyzer, plus it just generally outputs more oxygen. I don't want to get stuck with a 4 dupe colony

I don't think oxyferns were ever meant as your only o2 production. They're meant to extend the time you have to set up a proper system and make the start easier when you don't have easy algae.

If you don't have the oxygen (or food) to support them, a 4 dupe colony is perfectly fine. As Hedning said, oxyfern are a supplement, not a main source of oxygen.

If you don't have algae just get some rust. I believe the non-algae asteroids have a bunch of rust biomes. Rust Doxidizers are great. Just need to find some way to deal with the chlorine at some point.

I assume they where ment to replace terrariums on terra as there is no algea and no slime to produce algea.

Still if you replant them wild (eith pips) they can keep an enclosed area filled with o2 (if rarely visited)

The ferns can be useful, if you have created a "sink" for carbon dioxide in your base. I have such a sinkhole for Veradante bases, At the bottom a great place to grow mushrooms (takes a while , but 12 can sustain 16 dups easily). The ferns a level above and the (down) exit to the base. Is effective

You don't have to have only one source of oxygen. If you can produce oxygen for 4 dupes with oxyferns then that's 4 more duplicants you can support. Your maximum sustainable population is going to be limited by the ability to produce oxygen for them more than anything else.

Rust biome usually come with saltvines which eat chlorine gas so that can be your chlorine sink.

Ferns work fine when you build a Carbon Sink.

Water Cost depends on which map you role.
You could have no water problem at all simply having rolled an Ocean or Ice Biomes...
Depends.
Besides if you have limited Water you have other concerns such as how to feed your Dupes and then of course the question is why do you think you need 16 Dupes?

If your already low on water and there is no other water source you may not even be able to make Oxygen directly from a Hydrolyzer.

If you had plenty of algae,
Then most people will tell you that the Oxydizer is the best, but the algaeterrarium is the best and that costs you water but gives PH2O which gives off PO2...Which ultimately means more oxygen without a much heat cost component assuming you give them lights.

Yes to all this. Very yes even.

[Hedning]

Late game they do suck though. If I have rust I want to convert it into iron ore. This has o2 as a byproduct. When I'm launching rockets I need h2 and h2 production has o2 as a byproduct. I really don't need more o2.

oxyfern are pretty handy for eradicating stray CO2 that has pooled in places where it isn't welcome but where it isn't justified to setup a real solution like the skimmer or a pump/vent. They excel for keeping low lying places that are infrequently visited, oxygentated. They are not a solution for oxygen/CO2 for the main base.

They're also far better off left wild due to the water use, or you can try and get a Pip to plant them for you.

[Prometheus]

Electrolyzer is obviously the long term solution. However ferns cover you very well until you get to that point. The forest biome start is supposed to be harder than the sandstone/copper biome. So expect some limitations.

[Arieth]

I believe you are able to let seeds just sit on Soft or Firm (Superhard digging) Materials, And because it would be wild Oxyferns, it takes nothing, Also, What Blake Walsh said,
"oxyfern are pretty handy for eradicating stray CO2 that has pooled in places where it isn't welcome"
