How to make sure your plants never die


Recommended Posts

I've seen some posts about colonies failing because of crop overheat or low pressure.So I'm sharing some farming science.

In the current build #208689 plants still grow like normal when in complete vacuum. (not almost a vacuum, complete vacuum)

The tool tip will say "Atmospheric pressure too low" but it will grow anyway.

Also the food that drops off is in a preserved state so it never spoils.

The Dupes can access the crops/food from an angle but gas can't get through.

A complete vacuum can be made by filling in the desired area completely with bricks/mech doors then deleting them.

Happy farming

You can also just leave oxygen, or anything you want in there, and use insulated tiles.
The air will never change pressure, or temperature. You can see examples of this in any of the self sufficient base designs on these forums. They just grow repeatedly, and no need to ever check up on them.
There is not really any point in preserving food, unless you have an excess, and there is no real point in having an excess either.
Considering food doesn't need to be cooked or processed in any way, it's one of the easiest things to get going early on.

It will change temperature.
Those insulated tiles reduce or slow down heat transfer but not stop it. Of course if it is in the middle of base it would take very very long time...

And for flowers that are OK up to 29 °C it is no issue but if you want to have cooler areas insulated tiles are not enough even in real situations.

I have this hatch room in top-left corner of my base and I made it perfect 17 °C and hatch was happy for some time but now there is 22-24 °C and he is overheated.

Edit:

I should correct myself a bit... there is currently a bug that reverts tile temperature back to what they where built when game is saved and loaded.
So that's why it might seem as perfect isolation now but that will be hopefully fixed tomorrow.

For test I let my base run 50 cycles on max speed without doing anything and insulated tiles between batteries and my "cold" base part become 60°C and where totally heating my base.
But when I saved and loaded, those tiles where back to 20°C.

This picture is just after 20 cycles - insulated tiles between batteries and base room are already red hot at 40°C.

So I tried expanding the plant room and I noticed something ... if you grow plants in a vacuum and then restore pressure  they continue to grow (duh) but then they become immune to low pressure/vacuum until they die and you have to replant them.

It becomes worse the more cycles you have. And it's not limited to tiles you build yourself. At about 900 cycles it's not possible to play more than 20-30 cycles before everything on the map is almost steaming. And that's even with having everything that produces any heat fully encased in abyssalite or in a vacuum isolated room.

Hopefully, they also fix that bug.

I didn't get it, do you wanna say, after cycle 900 the entire map temperature became insane hot? And there is no point what so ever you have on your base and where, so plants will die and dublicants get starved?

Yup. Well, you just exit and reload and it's back to normal but it gets more and more insane.
