Preventative Feminiser. Add to working solution pre flowering to prevent male flower contamination on known hermaphrodite or gender unstable plants. With age, stress or heat, plants which were once genetically female can start show male characteristics. This product will prevent this from happening. Prevention is always better than the cure. Use just before and during flowering cycle as per direction. NOTE: If male flowers have already occured, See Budwise for follow a up after treatment to prevent pollen dispersal. It basically sterilzes the male pollen so it can't do any damage.
