Not sure,just applied my intent whenever i felt
like it over a period of 4-5 days(sometimes up to
10 times a day.
I used three samples of water and rice,one i applied positive intent,the other negative intent and the 3rd
no intent as a control.
Had amazing success....positive intent resulted in
a sweet smelling rice ferment,negative intent yielded
a foul smelling black scum and the control didn't
change much.
