The Takasumi charcoal has arrived in a big box. I am still thinking about how to use it.
I will be marinading some of it in comfrey liquid but I am thinking of trying some of it neat. I reckon that it would be more effective if inoculated with nutrients, however I might be wrong.
Lots of the experiments that the commercial firms have done are using pot plants. What might be illuminating is how it affects containerised tomatoes in the greenhouse. The conditions there might be a little more homogeneous than outside and the growing medium used could be from the same batch.
This I will do.
