Hardening off

Hardening off

Adapting plants to outdoor conditions by gradually withholding water, lowering the temperature, increasing light intensity, or reducing the nutrient supply. The hardening-off process conditions plants for survival when transplanted outdoors. The term is also used for gradual acclimatisation to in vivo conditions of plants grown in vitro, e.g., gradual decrease in humidity.
