that is a nice system although a little small...what is the height of those bins. Would they not fill up too quickly? They are good for a start though and can be used again for something else when you want to upgrade your bin.

Those nursery flats are brilliant, why didn't I think of that?

I figure if you want to augment the system, just add extra levels with more of the trays

Right after I got my Worm Factory, I saw a tray sitting in the corner of my yard and realized I could have made it myself. D'oh
I may get a second system going (mainly to put those trays to use).
