The kefir grains have been rehydrating for 4 days and they look rehydrated but don appear to be doing anything. Should I wait longer?
Go ahead and transfer the kefir grains to new sugar water to start the first batch of water kefir. It’s not uncommon for there to be little or no visible activity from the water kefir grains at this stage. However, it is important that the kefir grains not sit in the sugar water too long or they will run out of sugar to eat which can damage the kefir grains.
