How long should you let greenhouse grown vegetable plants "harden off" before planting them in the garden?

It takes roughly 7 to 10 days.
Place plants in a sheltered, shady spot outdoors. Under a tree or even on your back porch is fine. Leave them for 3-4 hours and gradually increase the time spent outside by 1-2 hours per day.
Bring plants back indoors each night.
After 2-3 days, move the plants from their shady spot into morning sun, return them to the shade in the afternoon.
After 7 days, the plants should be able to handle sun all day and stay out at night, if temperatures stay around 50 degrees F. Keep an eye out that the soil doesn't dry and bake the plants, if the weather is warm.
After 7 -10 days your plants are ready to transplant. Try to do so on a cloudy day and be sure to water well after planting.
