Thanks a lot for your answer, I am new to this subject of KNF and are taking the time to make all the solutions, before I start using them in my land. I consider your answer is the best you can give me, but is a shame Master Cho does not have an easy method to use rocks or rock dust, as does JADAM.
Thanks again for your prompt answer, I hope I can share my progress with you in the future.
