Sorry, no pics because my set-up is torn down right now.
I have an unheated basement, so winter temps are around 60 deg. I lower two florescent fixtures from the ceiling and set my growing cells on a table underneath them, keeping the lights as low as i can to still cover all the seedlings with good light.
As seedlings emerge, i run a fan through the day to move air and help the seedlings build stem strength.
My cells are large "conetainers" purchased from stewe and sons.
Its pretty basic, but works well for me.
