What is “Hardening Off”?
Hardening off is the gradual process of strengthening seedlings against the variables of outdoor living. (Strong sunlight, wind, cooler temps) To harden off, move seed trays outdoors for several hours a each day. Avoid exposing them to direct sunlight immediately. As the temperature begins to rise outside, they can spend longer and longer periods of time outdoors. Typically, the whole process takes one to two weeks.
