BSFL Castings for Red Wigglers
I have a bin of black soldier fly larvae. I love the way they process large amounts of food scraps so quickly. However, I have read that the resulting castings are not stable compost. Several sources recommend feeding the BSFL castings through red wigglers.
I can not figure out, however, how to harvest the BSFL castings. My red wiggler castings are easy to harvest. I just kind of mix the bin, the worms bolt toward the bottom and I scrape the black gold off the top. Things are not that clean in the BSFL bin. The big maggots infest every level, making the separation very difficult.
Any ideas? Anyone with experience?
