I have grown some seeds from a bag-o-schwag indoors and the results were crappy because of the lighting I guess. stringy small sativa buds. I also grew some bag seeds outdoors and it was stinky skunky grade A+ good shit. The sun is way more powerful than a grow light. Remember that good seeds for indoor growing take many generations to make. They are bred to handle lower light intensity and give a higher yield, etc.
