Hello,

The seeds that you are thinking of is "Lowryder". This strain is a hybrid mix between Williams wonder x Northern Lights #5 x "A ruderalis type plant".

They are available through the following two sites.

drchronic.com - (Look under The Joint Doctors seeds)
Treatingyourself.com - (Again look under The Joint Doctor, this site also sells Lowryder crosses created by MDanzig. The crosses do not all autoflower, you will get between 25-50% autoflowering plants with your first couple generations. After that the autoflowering trait seems to kick in a bit better and you end up with about 75-80% autoflowerers).

Hope this helps.

Peace
