Brian,
I definitely think there is some potential in commercial hydroponic
vegetable production. But in this matter, charcoal would be
competing against coconut husk (coir) as the main rooting medium
which has replaced rock wool in area greenhouses.
To be fair, you should be comparing the wholesale price of the soil-
less mix ($700) to the wholesale price of charcoal - $200/ton. No?
This makes it a lot more interesting...and feasible.
