ahhhhhh srry man i was confused i didnt see you had stated u wanted an auto lol erm, yeah, autos are generally considered to be less potent than their photoperiod counterparts so finding a low thc variety aint gonna be a problem. But as before, nearly all breeders will give a thc rating for the strain, either by showing a % or by simply stating 'medium/high thc'
You could try a lowryder strain but there is simply so many strains out there you could try, and almost all breeders are making their own autos too.
Are you from the states or from UK?

personally, the lowryder #2 is nice and frosty, its sweet when growing but when i dried mine it smelled like nettles, kinda weird smell, but not really fruity just like a sharp veg smell. I wouldnt grow them again coz there are much fruitier buds around. But it could be a good starting point with autos because they are considered very stable. I smoked an almost pure joint of it and was stoned out of my face for most of the day, it was a bit of a paranoia high but i was so buzzed i just ploughed through the paranoia full of energy. We went to the london dungeons which was really trippy and probably made the high better because the actors attracted all the attention to them. Was good fun
