I believe the arrivals botany should start with a High capacity water tank instead of the normal one!
I don't know of anyone else, but when I play clown or mime I generally always use the arrivals botany to grow more bananas and Holy Melons. The biggest problem besides the stone-age equipment (which is fun and provides a extra challenge) is the extreme lack of water. I constantly find myself using 3 then 4 water tanks to grow the plants and gain enough biomass for the things I want.
Eventually, I will be running around the station maintenance looking around with a purpose (looking suspicious as hell) while snapping my fingers try to find the next water tank to drag off into my lair like some sort of defiled water boy.
EDIT:
I seem to be not noticing important things.
