Chow_13answered grow question 2 years ago If both plants( male and female) were automatic chances the seed will be automatic. Its rare for an automatic to revert back to a photoperiod but it does happen, The genetic's that make a plant photo can be passed on but recessive. Strange its only one seed. Usually when this happens it from a herm that grew a banana or pollen sac's that were not seen. If that is the case then the seed would be unstable as it only has female genetics and is missing the male counterpart.
Happy Growing.
