What’s your opinion. Does ratio of scooby to liquid matter?

My first time making kombucha. Sorry if this seems like a silly question. But I’m looking for some pointers. I’ve purchased this scooby and notice it says 1L on the pouch. I have bought a 5L jar to ferment the kombucha. My question is should I just make 1L or kombucha the first time I do it? Or if I make for example 3L or 4L would the scooby grow? (Like a goldfish if you put it in a larger tank) or would it hinder it in some way. What’s your opinion?

If I do make 1L would I be able to make more later on. Will the scooby grow and adapt?

Thank you for any help.
