I start my seedlings on a heat mat until they sprout. Once they have sprouted, I put them under my grow lights. I use grow lights that I purchased from Chraley's Greenhouse. ww.charleysgreenhouse.com. I have two sets of two tier grow lights, the top light and the bottom light both have two sets of 40 watt bulbs. You can use shop light fixtures, but the right bulb and the right day lenth is what is importrant. Many seeds require a long day like 16 hours of light. But there are some flowers that require a shorter day. Doing some reading on line, or in garden books will help you out with the right amount of light. There are many books availaable to read on growing plants under lights.
Below are some pictures of the plants that I grew from seed under these lights last year.
