Do I have to prepare the milk kefir immediately after receiving it or can it also be stored?Updated a year ago

All our crops are alive, so they can't go indefinitely without nutrients. Once our package arrives you have 2 options:

You start right away and produce your first own milk kefir.

You send your new roommates into the fridge for the time being, after 2 weeks at the latest you should start the fermentation.
