Tomato Hardening

Anonymous added on March 22, 2011 | Answered

I have grown tomatoes and eggplants from seed under artificial light. I attempted to harden them off once before when they were 4 inches high. They became sunburned. Now after two more weeks in the shade outside at 70 degrees (average temps in the day) and around 45 at night, I am scared to put them out in the sun again. Can you provide any tips to make my second try more safe for my plants?

Move them slowly into the sun. They need to build up a tolerance. The first day, just do a half hour in the sun or so and work them up from there. This article will help too:
