Great points you bring up in this article about composting your own live soil.
I could claim that this compost above was a 'hyper soil' with a certain strain of slimy fungus in it, and some people would probably buy it.
Insane.
That is certainly true, and in my opinion one of the issues with the industry. It's easy to choose the next buzz words and slap it on a bag and clueless people will buy it right up.
It makes more sense to learn how to compost your own.
I utilize a type of fertilizing composting, which is not really composting, while adding blood in a composting type of way to the soil I have sitting nice and moist in a bin. It sometimes grows mushrooms too :)
If you grow indoors, it might be different. But then you are on the wrong path to be begin with.
That doesn't leave a good taste for those who believe we take into the field what we learn in the books, or maybe better put as a question; how can it be starting off on the wrong path when valuable insights can be taken into outdoor growing? It seems a little cynical towards indoor cultivation the way you put it. Can't say that I agree with this perspective but that's ok.
