I set up my lights to shine on my tomato seedlings starting this morning as a very few have poped up already today. The start of all those seeds I planted growing.
I have a very, very basic setup. The trays are on a shelf directly at the windows and then I simply set up two reflector clamp ons to shine light on them. I have two different fancy growth bulbs for plants. One puts out the strangest red light but I do know that one works as I tried a test case in the fall of seedlings just to see how I do. They grew great with that light.
