temperature issues

Items and tiles that don't produce heat on their own keep the temperature of the material from which they were constructed. And keep it forever. Yes, it is weird. Having a planter box made out of 125 degrees clay killed my whole farm.

surely the heat should dissipate over time, and how are you meant to keep track of what temp materials are dug from?

Yes, they should, but currently don't.

In my current game I gave up on building from granite and use only sandstone which comes only from your starting biome.

In the long run temperature kill your dupes. Not water, lack of oxygen or sand. High temp -> no plant -> no food. But if you crative you can find very cool areas in asteroids and magane farm there. Now you can be alive forever

 

currently running my o2 through a cooler and into my farm temp dropped from 29 to 22 in the room.

Planter box don't want to give their heat XD played next few days and the temperature doesn't change
