Notes on worm Behavior:
●Worms will migrate upward into the upper working tray to search for food.
●Worms will re-eat their food sources several times. This means worms will
migrate up and down the working trays.
Therefore, it is important to make sure the bedding in the lower tray comes into
incomplete contact with the bottom of the upper working tray to allow the worms to
travel through the trays, and there is no hard barrier(like sheets of newspaper or
others) between trays to block the worms migrating between trays.
Worm-castings Harvest
Keep feeding worm foods into the top working tray. Most of the worms will migrate
to the top working tray for food. The bottom working tray will contain only the worm
castings or worm compost with only a few worms.
When the bedding material in the bottom tray is nearly black,and resembles soil,it
is time to harvest the tray.
If the bottom tray is ready to harvest but there are still some worms in it,which you
would like to keep in the bin,it is very easy to separate them from the tray to be
harvested； simply remove the tray to be harvested and place it on top of the top
working tray,and cover it up with the V-Board. Plow the bedding in the tray to be
harvested several times during the day. The remaining worms will move down into
the tray below because of the light. Once the tray is free from worms,it will be
ready to harvest.
Empty the tray that is ready to harvest onto a piece of plastic sheeting. The
compost is now ready to be used. Rinse the tray with water； the rinsed water
also contains rich nutrition that can be used to water your plants. The cleaned
tray is now a new working tray for the continuous rotating cycle.
