Auto or not?

So I have a K2, a Purple Haze and an Afghan Kush Ryder. The AKR was a freebie from Attitude. Is it an auto? It said nothing about being auto on its packaging and I seem to remember Attitude differentiating between an Afghan Kush Auto Ryder and a Afghan Kush fem when I got it, but they no longer do... Also, I have read somewhere they plants called Ryder's are autos!? Anyway just curious if I imagined that attitude had non auto Afghan Kush...

Yes that is a auto pretty much anything that is crossed with a Rudderallis is going to be Auto.

uSo... The AFK is in there with the K2 and PH. What should I do with lighting hours? Sorry I know these are stupid questions,... They're just on 24 at the moment.
