OK, folks, you convinced me. I hauled out my T12s, and now they are under 14 T12s and two shop lights. Thanks for your help on convincing me to do more work.

The water is bit more tricky since I have a non-gardener watching them who killed hundreds last year with over watering. Here is how I organized it: an 8 ounce Dixie cup filled with dry ProMix HP is 1.5 ounces. The same cup properly watered weighs 4.5 ounces. So I have a digital scale in the room. Every four days, my helper will weigh a random set of 3 cups from each tray. If the weight is below 2.5 ounces for any one from a tray, he will add 50 ounces of water in the bottom of the tray. Et voila!
