I don't really know if it would be a stable cross as lowryders autoflowering gene was an anomaly which benfitted the grower from what I heard.

Theres only one stable cross I've heard of which is AK-47 and lowryder, which is minigun. I don't know if you could get a stable cross.

But Grow it and see the sex, if you r SD is a male then crosss it with a female lowryder.

Be sure to pollinate your lowryders with each other so you can have shitloads of seeds though.

Hope it helped
