Karma's D-Kush
Rez's Chemdog-Sour Diesel
Connoisseur's Fuel, Connoisseur Chem, OG Chem
Are a few that come to mind to look into
Nice suggestions. I've never personally had anything from Karma but I hear great things. Most anything from Rez or Connoisseur Genetics is fire, I've grown both of their gear.
