you can hermie an Auto man, multiple ways to do it but STS & Coladoral silver or gibbrilic acid are the chemical way of going about it, but there are other ways of stressing the plant out to make seeds, one way to achive it is rotherization sorry im not the best speller but basically you just let a plant go into flower for a very long time meaning like you give it dubble the time it would normally take before you chop it down my understanding on this it is the plant wants to make seeds that is its main goal is to continue its genetics and after being in flower for so long without being pollonated the plant goes into panic mode an throws off flowers to try an seed itself.
