If you have any seeds you saved from some good seeded bud use those and that would be free. Big Bud and Chronic are relatively cheap good seeds and are not very difficult to grow and they produce a nice yield. I chose both of these for my first grow and they worked excellent! Still grow tha Chronic. Stay away from the white strains for your first grow as they are more difficult to grow. Keep it simple and small for your first grow and GOOD LUCK TO YOU. : )
