I am starting seeds inside for the first time-trying broccoli first to plant out for a fall crop. My husband bought me a simple florescent grow light at walmart. the package says it puts out 75watts-it is a 24inch setup. the back of the package says it is 120v 60hz 17w 300mA. will this give out enough light? If not what kind of light should I buy, preferably something I can purchase from Lowe's or Walmart. I don't need anything elaborate-just a simple,basic setup. how close do I put the light to the seedlings? thanks for any advice to get me on the right track.
