So this is how it works: I turn on all the lights around 7:00am. Pull out the flats, water everything (1-2.5 hours depending on the dryness) and then normally plant some more seeds. As you know, I'm out of dirt (odd thing to be out of) and out of money to buy the spendy bags so I am waiting until my husband can bring home a truck load. Gardening will most likely not be a 100% success this season with the late starting seeds. Anyhow, throughout the day I slide the flats in then I rotate them and then they are slid one more time. It's very labor intensive. Of course, this process could be eliminated by having two lights on each shelf, but 42 shop lights affect my light bill enough already that I couldn't imagine doubling that! Every year it gets a little better and I learn a little more. I just have to accept the failures with grace.
