Yea H202 will have roots smelling like fresh radish. It keeps roots really clean. It kills micro life in the soil that convert organic material into usable food to the plant, a reason I would not use it in a organic fertilizer program. Check out "hygrozyme", it is a enzyme that breaks down dead material like dead roots and breaks it down quickly. Hygrozyme would be best to use with an organic program and it will not hurt microlife if used right. If you are not 100% organic then yes H202 is the way to go for a good cleaner.
