I think Satica (near the corner of Galena & Hampden/Havana) has them beat as the worse as they actually had product with mold on sale. Only 4 or 5 strains, all looking like it was grown with a 65w CFL and to have mold on it. Wow doesn't get any worse than that. It's too bad too as the place itself is decent looking. It was the first time my girlfriend has ever seen me walk out of a dispensary with a look of disgust on my face.
