Help Please ! What Kind Of Seeds For Me

Hi, i'm in northern ontario,would anyone know what kind of seeds for this area with high yield

depends on indoor/outdoor. im guessing outdoor since you dropped your specific region. then check to see if the flowering time/finishing date gives you enough time to grow after the last frost. and then factor in what you like to smoke. indicas, will put you on the couch for the rest of the day and sativas will give you a more subtle, mental, thought provoking high.

Northern Lights, for indoor high yield very forgiving. Wish I could get some.

Welcome OP but please post in the *appropriate* forum from now on. This does not qualify as a "Do it Yourself" thread.
