The other day, my husband helped me to make a video showing how to harvest the castings from my flow through worm bin. The clear advantage of having a flow through worm bin is how incredibly easy the harvesting process is. During this harvest, I got about 13 pounds of beautiful vermicompost, but only found a grand total of eight red wiggler worms and no cocoons. There is no other in-home red wiggler composting system that is so quick and easy to harvest.
Here is the link to the video. Please let me know if you have any questions!
