well, its simple, the ruderalis type of marijuana plant relys on time, not light cycle to finish. so people take the low thc ruderalis and breed it with more potent strains until the characteristics they want are stable. by selecting the type with the characteristics that match that of a certain strain, making sure it autoflowers, and BAM you now have a more potent, autoflowering plant that will finish in a very short time under any light cycle.
to be honest i ordered diesel ryders over a year ago and never got my beans(somtimes this happens) and after that i ordered auto ak47, and after trying to find a location, havin to start and stop, and to many idiots in the group- out of 9 beans that germed i couldnt finish a single damn one lol.
so im angry with auto's but its soley out of spite for the money i wasted, i hear the final product can be worthwhile. but im sticking with good ole fashion beans, no question on quality and i can grow them as big as i want.
