This weekend I'm going to do a little work. First I'll raise the lights a bit and then see if I can find my timer switches. I'm going to try switching the lights off for 6 hours a night. Then going to hit the hardware store and get three warm white tubes.
Thinking about trying some other plants. Going to give lettuce a try first, by all accounts it seems to be the easiest to grow, and grows pretty quickly. May also try carrots, peas and parsnips. The lettuce first. Saw a nice idea for growing salad greens in a piece of gutter. I suspect 4' of gutter could keep us pretty well supplied with greens.
