Experimenting with a very modest bucket, which resembles a small continuous flow through setup. I've cut out the bottom and put some thick wiring from side to side, mimicking the pvc or galvanized steel tubing you often see folks use.
My bedding is a mix of shredded cardboard and rice hulls. I think the whole setup is two months old now so I haven't harvested yet, nor am I sure this is really going anywhere.
(Also, shameless plug perhaps, but I've started !composting@slrpnk.net for all types of composting including vermicompost !
Edit: I just noticed you actually already crossposted from there, but for some reason Jerboa does not show that here for me)
I'm not familiar with the details of setting up a Lemmy instance, but can't you already get the new instance up and running with a modified /etc/hosts instead of waiting for the DNS to be updated? That might reduce your overall downtime a bit.
