I have been raising worms for 20 years or more. Fishing, gardening, etc. I've lived off grid for 33 years and had a homemade septic system. It finally filled up and was useless. I saw the vermicomposting toilet article and decided to go that route. I'm lucky as my cabin is on top of my mountain and the plumbing goes out the back and down the bank. Automatic gravity flow. I already had a 4" pipe in place to old septic. Just cut and attached to my porta potty bottom. Filled in and been using it since June this year. Just finished topping off with about 8 inches of mulberry leaves. Should keep them warm over the winter. I am at 6000' in S. California mountains. Gets cold and snowy. I plan on putting a tarp over the entire box once it starts freezing for long periods. Pictures attached. I also use the mulberry leaves, crumbled up, as waste covering everytime I use it. I haven't been flushing my inside toilet into it yet, when it is really cold, I will consider that. I want the worm's to get really established before I start flooding them. I am also single and don't have alot of waste going in.
I had pictures of my step by step process but I just accidentally deleted them trying to resize them. Pictures are both from when I finished and just today when I filled with leaves. Just got the sock idea off a facebook page. Love it. Used it this a.m.
