When do I stop feeding in one tray and start another?
Since I am new to vermicomposting I have a lot of questions and have found most answers right here, but I am looking for some advice regarding one nagging question I still have...
I have one of those flow through bins that all you to add several trays on top of one another. My question is:
When do I stop placing food in the working tray and start a new tray on top? I mean, do I simply fill the working tray up, feed occasionally, and wait for the guys to process everything and then start the second tray for them to migrate into? Then, when I am ready to start a new tray will they stay on the bottom until all the food is consumed before moving upwards? If the idea is to ensure my little workers leave their castings behind and nothing else before moving upwards I don't want to tempt them with a new tray too early. How do I tell when it is time to start the second tray?
Thanks for the help
