Hardening off refers to the process of acclimating plants from indoor temperatures to the outdoors. Because plants usually are grown in greenhouses (or, as seedlings in our kitchen window!), they've been pampered.
This transition period is called "hardening off". Hardening off gradually exposes the tender plants to wind, sun and rain and toughens them up by thickening the cuticle on the leaves so that the leaves lose less water.
