There are lots of good breeders on there,but i choose from seed banks that are either cup winners or inducted in the High Times Hall of Fame. You can look at Barney's Farm,Big Buddha,DJ Shorts,DNA/Reserva Privada,Soma,Serious and Sensi Seeds. If you want to try a auto-flowering strain try Lowryder(Joint Doctor). There are more good breeders on there but those are the one's i prefer to buy from!
