I have no confidence in the 5% solutions. Why take a chance

John, my concern for solutions stronger than 10% was for the health of the rhizome. Like others, I sometimes forget to pull the rhizomes out of the solution and have been known to leave some in the solution over night.
I've used the 10% solution for years . . . because it's what I was told early on. It's good to know that stronger solutions will do no harm.
