At what density should earthworms live?

[damien]

For a bit more then a year I'm breeding earthworms, but I've never seen worm pee in the bin I put underneath. If I put in an apple, it can be in there for weeks.
I'm thinking that there are too few worms in my bin to have a steady culture (although I've never run out, yet).
Is my culture a normal one or is the density too low?

Worms make "casings" that look like stiff dirt. Really, that's all it is, digested dirt.

Then what is the 'super fertile water' some people talk about?

I don't know, soaked casings?

As far as I know if you have a proper wormery 'juice' collects at the bottom, in proper wormeries there is a tap to drain off this liquid, if you don't drain it off your worms may get too wet and drown. Alternatively, add some drier soil, or some other dry stuff like paper and it will soak up excess moisture. I have my worms in a storage box with no way of draining the liquid off, all I do is keep an eye on how wet the compost is.
By the way, the 'super fertile water' you mention is liquid fertilser which can be used for plants at a ratio of 1 part liquid to 10 parts water. Hope that helps, Kerry.
