Here's the direct link to Pat's FT...and here's just one of the photos. Click on the link to see the details. The harvesting mechanism is pretty cool.

I completely disassembled my second FT. It is designed the same as the one shown above. I got a consistent 30% usable VC each time. I took it apart to really see how many worms I had. They do not show themselves and few (in comparison to the overall population) fall out the bottom even with my harvesting system.

I love the mini flow through system. Looks like a good couple of pounds of worms in there.
