Just a point to consider and perhaps something good you might do as well
I have been making kombucha for a while now, and a had several extra scobys the other day (ASIDE from the few that I keep in the pantry in the scoby hotel) so I decided to toss them in with the worms.
I came back today to the worms and lifted up the scobys and it was completely underlain with worms. I mean, they formed a carpet with no soil visible under the scoby there were so many worms directly under it. I saw a LOT more worm activity in the whole bin as well (up on top of soil and moving around). They were obviously loving it.
