I'm moving my worm bin back inside to stabilize the temperature. I am debating if I should remove some material so the worms that are there aren't overfed. That or make a new bin for a second level and have my current bin as a leachate bin.
I currently don't see any worms besides the ones in ball of compost/worms I got to bump up their population. It may or not be a good thing but with a little digging at certain spots, I do find worms within the bedding. They may be the adventurous ones of the worms I introduced or they could be my old worms. So its really hard to tell if it is good or bad.
I am also bringing it inside to warm it up so it could have some mites to help out the worms. Mites never seem to have taken hold in the bin but in my rosemary cuttings, I used compost from my bed and its still teeming with mites. I'm going to try to bring back up my bed compost to that level and introduce some mites, again, to my bin.

I found a really old corrugated fiberboard outside today which I shredded up and soaked with aged water to be left outside for a few hours. It seems to have did the trick for my worms. I piled it on top of what I have and the worms are really digging it. I know the worms are after the microbes in the stuff they digest but I am wondering what did I do wrong with what I provided them (Lets call it "my base"). It has been around for a week or two already so it shouldn't be that poor in microbes unless something is throwing the whole system to hell... like pH.
To test it, I have been letting a pH test run for a few days on my base. My base mainly coffee ground based with coffee filters, tons of cardboard and perhaps some veg. Since the major pH player in my bin is the coffee grounds, I use that for my test. Initially it showed up as about 6.5 (ideal) throughout but now it slowly changes to 5.5 by the coffee grounds. I think its heading towards 5.0 which is what most worms can handle. Taking this in consideration... I wonder if my bin is dipping towards 5.0 at times.
The new corrugated fiberboard I used is aged and its pH should be more normal. So I think I am leaning towards my hunch. With that said, I am going to lime up my base soon. Egg shells with some more commercial grade stuff.
