1) yes, at this very minute

2) a yes, b) so-so, c) yes

3) nothing outstanding, it was low cost (good) so it didn't have many features (bad).

4) I did not get a "system", so adjusting the distance between the plants and the light is a balancing act (insert supports under plant trays to raise them up).

5) at 18 hours/day seedlings do not get leggy. on frequent cloudy days this time of year, seedlings get enough light to get a jump on the season.

6 & 7) no. plants reflect green light and absorb light above and below that frequency in the light spectrum. my grow light is blueish. so the red/orange end of the spectrum seems to be lacking. this is why is use a "GE kitchen and bath" light fixture in addition to the blueish grow light fixture. both ends of the light spectrum get covered. when you think about it, a grow light with a built in timer might be a nice feature. since I have multiple lights to cover the spectrum, I provided a timer with multiple outlets. they all turn on and off at once. FYI, I believe new plants need air circulation to prevent damping off. So (in my opinion) one needs a fan as well. it is on a different timer schedule than the lights.

I hope you come up with a new and unique design!

No I don't use Grow Lights. I use T5 and T8 fluorescent bulbs in 4 foot fixtures for growing seedlings.

The color spectrum in Grow Lights is only needed for blooming/flowering plants so isn't necessary for growing seedling transplants.

Thanks guys! I was surprised to get so many responses in such a short time. My science teacher shall be quite pleased.

I have a grow light set-up but I don't use "grow lights." They're expensive. I use full spectrum fluorescent light tubes. I am fully satisfied with them when they are 1" away from the seedlings.

The light set-up I have is from Park Seed Company. It has two levels and 4 trays on each level, with a shop light on each level.This wasn't enough light so I added two more shop light fixtures, one on each level.

Best feature is adjustable chains on the lights which I can lower and raise. I am very satisfied with this set-up and have been using it for over 20 years.
