As one of the major agriculture practices to improve on the yielding ability of the crop, hardening off is done to make the crop get used to the environment before transplanting. Hardening off refers to 1-3 week period of trnsition where indoor plants are acclimatised to much harsher conditions found outside as temperature varries from indoors to outside hence a need to provide good temperature to the seedlings before being taken to the outside.

Crop management

Because young leaves to direct sunlight causes bleaching, wilting, death and inreased wind also cause burn and stress to plants. All plants develop a clearish waxy coating over leaves and never expose young plants to hard conditions as cuticle is under developed.
Young plants with an under developed cuticle are much more prone to damages when put straight outside and hardening off begins 1-3 weeks before planting outside. Always pick calm, cloudy days at first without anyway wild swings in temperature and on cloudy days being best, put seedlings 2-4 hours outside in begining.
Furthermore, at 7-8 days, expose most plants to full sun and at 10 days put them from sunrise to sunset. By 2 weeks, all plants should be fully hardened off and finally, harden off the plants until weather is favourale for planting.
