That's what I meant, we have a robot on board with its chip backery.

I assumed freeze dried food, so a lot if not all (using special prepared
food) water would be extracted. Of course it won't be tasty at all.

In 72+18 days a member eats (72+18)*3=270 carrots
24 carrots per foot, so a member needs 270/12=11.25 foot
One stack has a length of 9*16*4=576 foot
So one stack has enough carrots for 576/11.25=51 people.
That means 20 stacks instead of 16

I wonder, do plants that grow large food (relative to the amount of leaves)
use more oxigen than they create?

I found at least one error, and have some doubts about the volume and how
much water is there in a single tray?
(It took me a while before I figured out that 1 feet is exactly 12 inches)
