Large seedlings started under workshop lights have been living in a protected environment and are not ready to be directly planted in the field. They need a gradual exposure to real world growing conditions to toughen up or be "hardened off".  Over 7-10 days, transplants are gradually exposed to sunlight, cooler temperatures, wind and less frequent watering before being planted.   Here's Jenny guarding the "babies" or is she wondering if there are any worth munching on?
