CHEM S1 Chem D (Selfed) (50-50 Hybrid) When you come from hearty stock, you can be sure you will carry the traits of your impressive parents. At least that’s the deal with Chem S1, which essentially means Chem D that’s been “selfed” or bred from a single Chem D seed thanks to the fact that once in a blue moon a seed will come from a male flower. Chemdog took that seed and cultivated into this Chem S1. Think: A stronger, more vivacious version of classic Chem D from top to bottom. PALATE: Diesel, conifer trees, pepper and distant mango. EFFECT: Uplifting and euphoric for productivity and mental sharpness that crosses back into subtle and satisfying, deep body high ideal for a post-work wind-down without a knockout punch.
