I have experience with Reverse. I use it with Penetrator, Full Botanicare pro line, and humbolts Bushmaster, Purple Maxx, and Gravity. My strain is a white widow blueberry mix (sugarberry). The mother is great and produces lots of bud in a SOG but does tend to have a few male sacs once in a while due to genetics.
I have used Reverse for a few grows now and have found no sacs, seeds, nanners or the like. This product has worked everytime for me and on friends grows as well. I use it as directed with Penetrator. I use it more as a safety pro-caution and would continue to use it even on plants that don't usually hermie just in case it encounters some stress.
