Greening mars to 100%?

[AncAinu]

I've finished the game and reach about 50% greening at most.
But afterwards, CO2 reserves go down, regolites gets emptied, and the greening process dimishes.
My temperature dropped, so I made a bit of GHG, which made temperature rise, but green still goes down.

I'm very confused (my CO2 level is 0, O2 level is 21%, N2 is 78%)

You'd need to import a vast amount of water. Earth has 70% of its surface as water, 20% as ariable land which can be farmed, 5% arid to desert, and 5% extreme desert where nothing grows.

If your water level is 500 meters, Mars is one third water (give or take?), one third ariable land, and one third arid/desert/extreme desert. 50% greening is pretty good.

Im looking at the same stats as you, at year 95.22.19 I have 34% Flora.
How did you get to 50%???
15.3 degrees C, 1202mbar pressure, water level at 500m.

I think you have to import more water, if you check your climate lenses you should notice that most of the surface is just dry. If you get more water there is more humidity and then your flora should grow. I only have roughly 500mbar yet but just passed 1000m water. Flora is already at 33% and still expanding. I have no idea tho if im doing good tho, maybe i already did something wrong that will kick me later ;)

The flora flourish until the Co2 is exhausted. Then some other kind of carbon cycle is engaged.

I dont think the water affects the flora% as long as there is Co2 and biome to expand into. Тhe water expands the biome in which the life can grow.

After heavy observation i was unable to understand what affects the % of the flora.
1. I have tried pumping Co2 using carbonate extractor, does not affect it.
2. Maybe I have a coincedance and at the same time population and the flora % increased. That makes alot of sence because people exhaile Co2. But that trend did not repeat.
3. Farms does not effect carbon cycle.
4. Then I saw a picture in the store page of the game where the flora seems like very high % and the pressure was 1430mbar so i tried pumping N2 to reach the pressure, also raised the temperature to 27deg as was in the picture, but that did not changed the % of the flora :(
Anyway, sometime after the Co2 is exhausted my flora % raised to a certain level and stopped. In my sandbox the % freezes to 53% and 46% in the campaign.

I really hope that there is a way to control the flora % after the Co2 is exhausted. After all we have teraformed the whole planet and there should be a way to do that too.

If the above is true then i wander if it is worth holding off on the Organic Material dumpsters to keep the CO2 in the atmosphere for the plants?

Raising water levels is a mixed bag. I hit a peak of 70% vegetation before I started importing ice to flood the lowlying areas and bring moisture to others, creating new viable biomes. Unfortunately most of those lowlying areas are in the tropical zone in the middle latitudes that vegetation grows really well at. You need a ton of water to fill in and connect the pockmarked crater areas, whereas vegetation happily goes from crater to crater.

Importing GHG to keep the temperature up helps too, in order to offset the plunge in CO2 or diminishing returns from comet/moon impacts. Closer to the south pole you can watch with the changing seasons, especially at lower temperatures, where vegetation receeds and springs back.

FWIW, I used to be stuck at ~46% flora coverage but then I have started pumping out CO2 using carbonate extractors and that seems to have worked (but slowly). At the same time, I'm using oxygen capture plants to keep the oxygen levels in check (I don't want to pump more nitrogen into the atmosphere as I want to stay at ~1bar).

I'm currently stuck at 60%, trying to get the new Home achievement for 70% flora. As above, there is no more CO2 production, even using the remaining carbon deposits doesn't boost CO2 levels. Tried scattering Biodomes and Humidifiers in the arid areas but they are only doing a limited coverage.

Research the "Atmospheric Humidifier". I think it's in biology on the far right edge of the teach tree. It uses water from your water network to spread humidity in it's area of effect. Then you can spread grass/plants on it. You can easily go past 75% with that method. I stopped at 75%.

I've been doing that, might need to create more of them and see how that goes. More likely to reach 1 million colonists before I get 70% flora at the moment

If you are far away from 70% and ran out of humidity zones, I think you can continue to import more ice/water to increase Mars' sea level. I did the achievements on easy story mode and ended up with about 700-750m sea level.

Update:
Managed to reach 70% flora by spamming Humidifiers where ever there was a barren spot. Nearly maxed out the build limit with support infrastructure. I should note I was playing HOME continuing on from my BLUE save, so water level was near max. Also flora gets really finicky when temp goes over 30C

I've found reaching 70% is not difficult IF you import all the water needed to fill in all of the "flood zones". This raises the humidity all over Mars. A few well placed biodomes and the plant coverage can get to 70% all on it's own over time. I boosted that to 85% using a combination of humidifiers with a biodome next to each one to fill in the dryer areas. the southern latitudes tend to need this the most.
