It only affects Creepvine growth in that Creepvines (and Bloodvines) will never finish growing unless the stack is at least two high. Otherwise no, the maximum size is fixed, stacked containments only affect the maximum number of fish that can live in there at once. To get it to be an adult you need to pick it up, take it outside the base and discard it from your inventory.
