each of those little catagories is a different seed breeder, some of the breeders offer "female" seeds", which will most likely be more money, but there is a breeder, female seeds.nl, that offer 4 packs and ten packs, i got a 4 pack of Nev.haze hybrid and a 10 pack of northernlights. the northerlights were nice and i havent done the nev haze yet.
