If you are looking for American clones I can recommend allpot in Vorarlberg (allpot.com). They have legit GG#4, Blue Dream, ECSD, Pre98Bubba Kush, Candy Kush and told me that there will be a lot more in near future. I grew out their GG#4 and Bubba Kush and they were both fire (low yield on the bubba though)...
