Hi Dave,
I read your article with lots of interest. To tell you the truth I didn't know exactly how worm castings were created so I learned lots! I'm going to attempt this method most definitely.
As you know our summer here in Phoenix is hot. We're expecting 111 today and 113 for the following few days. I do compost in the ground and have lots of garden earthworms that have appeared in that spot. They do a good job of feasting. However, they seem to disappear in the summer. I'm thinking I won't try the bin-harvesting until end of Sept. or early Oct. I just don't have the room in my tiny house to set up indoors.
Can't wait! Thanks for the article!!
