So I'm preparing for my first trip to the moon, and I want to know a few things first: How many units of air can the fluid tank hold? I want to build a bunch of air canisters, fill them up, and bring them to the moon. then i will decompress them and put them into the tanks and then into the sealer. With the oxygen collector, how do i get it to work on the moon? i understand that i need to place trees around it, but is it a special kind of tree i need to find on the moon, or can i just plant saplings from the overworld normally on the moon surface? thanks.
