hmm, though im not much of an expert on outdoor growing some friends of mine introduced me to a practice called "johnny ganja seed". they would just save the seeds from their shwaggy bags and toss them allover the country side. this would lead me to believe that for the most part its pretty easy to grow bag seeds outside, and you dont have to worry about sprouting and transplanting or any of that.
if you wanna be safer than just tossing them around id plant them. dont forget to put the pointy side up ^^

good luck man!
