If you can afford it, id also shell out a few bucks for seeds.
And yes, common sense will tell you to first try bagseed, cuz you will mess things up along the way.
BUT...With the help of the people on here, your odds of getting SOME bud at the end of your first grow are pretty good.
SO, wouldn't you rather smoke some Grand Daddy Purple, C99, or whatever else you get your hands on as opposed to, um, bagseed?
