Depends what your goals are do you want straight chem s1s or you trying to create a new fem line ? If you want straight s1s use another cutting from it to reverse then polinate another cut rather than just reversing it expecting it to polinate itself good enough works better that way and if your trying to create a new line then you could pop fems find the best and reverse that your better off finding a nice female in reg seeds then reversing that onto the chem imo tho
