the eternal search for a short auto sativa. My advice is to search for 50/50. That's the best I have found. Almost all the short sativa dominants out there are some kind of ak 47 crossed with of course ruderalis but also some short indica and by then it is about 50/50. The ones I have tried I would not rebuy due to very low yield and too many males., oh well, Hijack by auto seeds has a good stone and a light yield, about 2 oz maybe a little more, but I can't find it anymore in USA (herbies). 30 inches is the deal breaker.
I have some Heavyweight Massive midgets in the fridge for next grow. Like I said, only 50/50 but at that height probably the best for right now for me.
