Growing Sour Sapphire: what to expect

As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within Sour Sapphire can lean either direction. Growers familiar with GMO Cookies or Dirty Sprite 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.
