I have used Joey Weed's seed, growing it right now...it is nice strong genetics, all 10 seeds were viable. Attitude is a seed distributer, they carry many different breeders gear, Nirvana has been around for a long time and very reputable...Joey weed is good and cheap, and I got his gear from the Hemp Depot...and these guys are on the ball, very safe, and professional. Good Luck to you!
