Science Fair: Optimizing Root Growth on Plant Cuttings

Key Factors for Root Development

• Temperature: Warm (75-80°F) accelerates rooting.
• Light: Moderate bright natural light helps.
• Humidity: High humidity aids many species—enclose cutting and container in a clear plastic bag.

Experimental Design Tip

Test one variable at a time (e.g., temperature) while keeping light, humidity, and cutting type constant.
