Hardening Off Seedlings

To make room for the APS-6 seed starting units, I have had to start hardening off my Cherry Tomato and Winter Melon seedlings.  

 

I have 7 Cherry Tomato seedlings and 2 Winter Melon seedlings.  I plan to put them out in the sun for 3 hours the first couple of days.  I will put them out for the full day (~ 7 hrs of sunlight) afterwards.

I will take them inside at night.   I won't let them overnight outside until March.
