Good info @SDK ...thanks. And that's exactly my problem, was that the starter culture I got in the mail wasn't a very big culture at all. But I tried to spread them over 3 containers, one a tad smaller than a shoe box, the other 2 a bit smaller than that. I've been cutting up one slice of wheat bread into 6 slices, and putting in 2 per box is all. The large one seems to be doing the best, only because I think it got the 'majority' of the worms when I tried to split them up. The last time I changed it, I skipped a day ...went 3 days instead of 2..and they were moldy with the white hair type...yuck. I try to be careful scraping off the dirt too, cuz I do see some worms in the dirt attached to the bread slices.Two months isn't terrible. Also, if you feed them massively the culture just crashes faster, so getting to "just enough" is where you want to be.
When you are ready to redo the cultures, don't wait until they start going downhill. Grab a big pile of worms from a healthy booming culture. You can start your new one with many more worms than you received in the mail. This will skip you over the "moldy" stage, and your new culture will be ready to start feeding off in just a couple of weeks...
It's better to err by starting a new culture too early as they can crash quickly. I like to keep two running at the same time that are started two months apart. Then every two months start a new one, and toss or give away the worms from the oldest culture...
So it seems that I may be on the right track atm....getting some growth like I said. I'll try and post a pic if I can....
