Just giving you some friendly advice. The next time you tell people on the internet you have a garden, don't try to pretend you grow topsoil at a rate of a foot a year. That's like saying you have a 210 IQ. I might buy it, but you'd be linking your own videos.
If compost tea is really such a subbressed dechnology, post a timestamp to one of the vids you listed where the interviewee says a foot a year, otherwise I'll get to them when I get to them.
