beckygardener said:I was told years ago to use 1 "warm" light and 1 "cool" light in each shop light fixture to emit the full spectrum of light needed for the seedlings to grow well. That is exactly what I did.

That is what I did as well. I just did not want to spend the extra $$$ for "grow" light bulbs. Subsequently bulb technology came out with the "natural" light or full spectrum. When you use them, they provide essentially the same resulting light as using one warm and one cool. That is what typically I use now
