That's one method I read of.
Others included plastic trays of kitchen green scrubbers in perforated thick plastic bags, kitchen sponges in plastic containers with air holes and soil in wood trays. One blogger warned off using peat and garden lime because it's easy to overdo the lime and that'll kill the poor worms. You're quite successful using it, as you have multiple thriving colonies XD
My takeaway is the material varies but the bottom line is damp, neutral, porous living space that's kept cool and dark, remove any moldy stuff immediately, don't let the colony get too large or it'll poison itself. Harvest off the food/food tray/glass feeding gimmicker because it's easier than digging around, damaging them.
I loathe the idea of not taking care of living things properly. If you have a fail safe ratio for peat and lime you're ok with sharing, I'd be thrilled to rack a few dollar store containers instead of making trays. This is, by far, one of the cheaper methods out there.
The foam box stays. I don't have room for a second fridge, so I need a container to put the worm housing in that I can put a lunchbox sized freezer pack under. The lid doesn't get sealed, just placed over the top to keep cool air in. The basement gets close to 80 in summer, which is why I worry about keeping these guys in the first place. My fridge freezes things on the top two shelves, lower down isn't much better. I rent, so I'm not shelling out for a replacement.
Maybe worms are a terrible idea! Hahahaha ?
