How long does it take to grill a full rack of ribs at 300?

Grilling a full rack of ribs at 300°F typically takes about 2.5 to 3 hours. It's important to cook them low and slow to ensure they become tender while developing flavor. Wrapping the ribs in foil for part of the cooking time can help retain moisture and enhance tenderness. Always check for doneness, as the meat should pull back from the bones and be tender to the touch.
