Aerogrow seeds

Hi everyone.. I'm a newbie grower, have purchased myself an aerogrow, I'm just wondering if anybody can recommend any seeds from Canada I can order online that don't grow too high like lowriders or something like that I heard about. I figure these would be best for the aerogrow. I appreciate your knowledge and support.

Why does it have to be from Canada?

Here is a page of autoflowering seeds. I hear good thing about this place.
