Sorry, I'm interested in this, the whole biochar thing is new to me. I seem to be missing a step in there. So you get all these free wood products (nice!) you put them in barrels and soak them in rich organic, bacteria growing stuff for four days, like making compost tea but anaerobic (right? you aren't doing anything to aerate this mixture while it brews for four days?).
Then you said something about the weather is perfect for such a burn, and burning is implicit in bioCHAR. But the burn part isn't very clear. You do the soak in plastic barrels and then you said you have metal barrels for the burn. So you move all the now very wet, heavy stuff from the plastic barrels to the metal barrels? That sounds hard. And then you burn in the metal barrels. How do you get this soaked wet stuff to burn? What are you burning to get the heat to get the wet stuff to burn. Is it all in the barrel? Is the barrel closed or open?
What is the point of all the nice worm castings, molasses, fish etc, if then you are going to burn it all? Doesn't it just get burned off again?
Sorry, but you are into an area I am totally ignorant of, so if I'm sounding ignorant, it's because I am.
