I followed a video on building my own worm farm using styrofoam boxes. The video suggested having a box underneath the main box to collect the worm castings, so it required I put holes in the base of the main box and have an empty box underneath.
The instructions also suggested placing fly screen at the base of the top box to stop worms leaving and other insects from infesting from below.
I have added my worms and everything has been going smoothly and the worms are processing a large tub full of scraps every week, however the lower box is completely empty?
The boxes I am using are about 1 - 1.5 foot deep. I filled the top box with about 3/4 of soil.
I am wanting to know:
- Is the bottom box even necessary if I stack a box on top once the bottom one is full? I can empty out the bottom soil and use in the garden etc, right?
- If it is a good thing to do, is it maybe either the fly screen or I put in too much soil to start with?
- Was it even necessary to put that much soil in to begin with? I am curious because when the container is completely full and I add a top container do I need to semi-fill it with soil?
