David - Thanks for your encouraging posts! This is all new to me! I am doing pretty much the same thing as you are doing. In my garage, but I don't have dry stuff on top of the soil. I added burlap cloth over it and misted the cloth to make it damp. I use that to keep the fruit flies out. I also keep the lids on both bins. I will say that my son turned the light off in the garage one night. When I checked on them the next day, one bin had the worms climbing up the inside of the bin, but the other bin the worms were NOT trying to escape. The difference in bins was I believe the moisture level. The escapee bin was much damper. I also think I have been underfeeding the worms. I added more liquid food and the worms were all over it within a matter of a few hours. They seemed very hungry. I was too worried about over-feeding, so I have not been feeding them but a couple times a week. Apparently I have enough worms to be feeding them probably every other day.
I have 2 more questions I hope someone here can answer:
1) How often do you add lime to the worm bins?
2) What kind of grit do you use for the worms. I know worms have gizzards and need the grit to help break down the food. (Though I do use my juicer to pulverize the scrap food before feeding it to the worms. They are all over this liquid food when I add it to the worm bins.)
