I think Plants should need water to grow. maybe 1 watercanister for 24 ingame hours. a special cargocanister as a tank for all plants on a ship/base could be added. water extractors should be crazy effective and fast, like using only 1 powercell for a stack of water (after all punping water out of a lake is easy, even for todays technology) that would also encourage players to go and get the water from a planet... (and also make it unnececary to place "a lot" of water extractors just because those take forever to get a stack)
