i'm afraid not hybrid. As far as I know the only thing Reverse will do is halt the growth of male flowers on a female plant. It won't change anything on a male plant at all. Rock said he thought it slowed regular male flowers but I think he just had a slower growing plant to begin with......I never saw it slow down (or change) the males I used it on before I went to female seeds. But it cerainly stopped ALL hermies in their tracks right up until I developed a continual light leak. I've gotten THAT stopped this grow but only time will tell for sure.
