This is my first time starting apple seeds, but I am an old hand at
tomatoes.
To help my tomato seedlings grow strong stems, I plug a small fan into the
same timer that runs the grow lights. This makes the seedlings stir in
the breeze created by the fan and replicates natural coditions.
I will try it with the apple seeds and let you know.
I wonder if the moving air has prevented me from ever haing problems with
damping off?
