Ya only half the Mykos dissolves leaves the granules in my buckets too but helps me remember it's there. I should probably use great white or something hydro based but I like this and my roots are sure starting to get beefy. My 2.2 lb bag has been threw 3 cycles and I can get another 2 out of it before I need to break a new bag open. tbl spoon per gallon goes along ways and they say you can stop 2nd week of flower I did last grow not gonna this time.
