I don't buy the "grow light" bulbs anymore. I buy one "Cool light" bulb and one "Warm light" bulb to use for my seed starting area in the basement. Check the packaging and buy the two bulbs that will give you the widest spectrum of light. The two bulbs that I got actually gave me a wider spectrum of light than the grow light. I turn the try around every day to make sure the light gets evenly distributed and I have always have very healthy starts....
I'm going to try the cold frame inside the greenhouse. That might actually work for me. I also just hung a light fixture and will be getting some grow lights to add next week. We'll see if that helps.
