I've had succes in keeping autoflowering strains going by keeping them under light 24/7.
They do start to autoflower but if your patient (I mean real patient) and keep them on a growth diet they do eventualy break out of that cycle.
Mine took over a year of this but now i get new growth and can now take clones and saved the breed.(even the original breeder doesnt have seeds for this breed anymore)
The breed finishes outdoors by mid-august... no wonder i wanted to save the breed...lol

OK,enough of me babling...(damn this weed is good )
