Save your money, OR better yet, hit friends up for seeds.
A bad seed is a rarity among growers, these days. Seeds are generally an accident in a garden of top quality plants.
Yes, there's the risk of a hermie, but you'll save money and time.
That way, you can gain experience, save money and buy seeds before next year. AND you'll have buds to smoke while you're doing those things.
Best of luck!
