Step 8: Harden Seedlings for Outdoors

Before planting outdoors, harden seedlings off first to acclimatize them to the change in air and light. Hardening takes from 10 days to 2 weeks. Place seedlings outside in the shade for a few hours each day, increasing the time every day until they remain outside all day. Never leave plants out in freezing weather.

    I enjoyed the article, “How to start vegetable seeds indoors”. I have several fluorescent lights in my house that I thought I would use but you do mention that you need full-spectrum (daylight) bulbs. I take it, these bulbs are different that everyday fluorescent bulbs and to be effective the full-spectrum bulbs are necessary.
