Growing OB-1: what to expect
As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within OB-1 can lean either direction. Growers familiar with Unknown Strain 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.
