Jonas, I have been reading and re reading your blog posts about soil types and again found your posts super helpful. I have been learning as much as i can about the different soil types.
I know the ready mix you sell is 70% clay king and 30% pumice. I understand that clay king is akadama, kanuma, and kiryu. I also understand that kanuma and kiryu are named after the areas they are harvested in Japan.
What exactly is kanuma and kiryu?
What is the average % of each in clay king?
With your ready mix would adding lava rock to it be pointless since it already has pumice to make it dryer?
