You could spend the extra on Feminized seeds to ensure an all female cast. Thats what I plan on doing well for one strain but the other is up in the air. Has a strain caught your fancy yet? I want those awesome Delta nine seeds, its CannaSutra and I've heard its nasty. Oh the site I used in the past and am planning on using is Cannabis Seeds at Auction!
good seeds at auction so you get a few deals on seeds. I think most sites want 200 and something for them but I'm grabbing them at a cool 90 (80's style) Good luck mate
