This is old news. This type of plug flow digester has been around since the mid eighties. Still a good idea for farms.

However, the 30% vinegar is quite toxic to the humans applying it. I bought some to try out after reading the label I decided to abandon the idea.

I just deleted all my previous posts on Reddit. Want to erase everything I can before leaving. Any hints on best way to wipe clean to avoid being used by AI?
