Optimum lighting distance

Since I've got a lot of stuff starting to come up , I went ahead and made some brackets to hang that 2 tube flourescent fixture over my shelf . I have 2 gro-lux 40 watt tubes , and am wondering how high I need to hang the light . I'm currently hanging about a foot above the plants , seemed about right ... but I can go down another few inches or go up to about 2 feet .

as close to the plants as possible so they get the max. rig your setup so it can be raised as needed.

the plants grew. The fixture I had was hung with chains so it was easy to raise it up or lower it. One year I started plants with the lights about two inches above the pot, they came up quickly and grew so rapidly they were spindly.
If you can get a small fan and start blowing air slowly over the plants, will make the stems much sturdier and the plants will be stronger. I used the ceiling fan in my office. Was still working as a technical writer at the time and it was nice to look over and see the plants growing nicely.

The light is suspended over the plants on chains , I can lower or raise them as needed . The purpose of the light is to supplement the sunlight , as I think our double glazed panes only admit like 60-something percent of the light . The ceiling fan does stir the plants some , it's set to blow "up" so the warm air flows down the walls . Most of the tomatoes have sprouted , I wish the peppers would show some green ... I planted a couple of pumpkin and a couple of acorn squash as a germination check , looks like my saved seeds are viable !
