Growing High School Sweetheart Breath F2 x 9lb Hammer: what to expect

Growers familiar with 9lb Hammer or High School Sweet Heart Breath will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
