well it might be possible, ive never heard of anyone getting more than one harvest out of just a single auto though. if u succeed in getting more than one harvest out of it then post sum pics, and share with ur fellow smokers and growers on how u went about doin it. i was gonna buy sum autos online before and sell half the harvest so i could buy more seeds for anouther harvest. that would be an easier way for u to go about doing it, probably faster too.
