Seed Starting Under Lights: Bulb Choices and Timing

Use inexpensive cool-white fluorescent tubes until seedlings reach 3 inches. Then add a couple of 40-watt incandescent bulbs for red wavelengths. Run lights 16 hours on/8 off via timer. Start seeds in egg cartons with sterile media, covered with plastic wrap. Move outdoors to shade in mid-April, transplant when sturdy.
