Don't be insulted by the title. It's probably the best article I've seen that explains and compares the incandescent, fluorescent, mercury vapour, metal halide and high pressure sodium lamps as light sources for indoor gardening. I subscribe to The Growing Edge, a US magazine out of Oregon. It can be bought in magazine stores in Canada, and highly recommend it, especially if your interested in hydroponics and light gardening. Briefly, I agree with Don Parker in his article, fluorescent light sources such as grow lux are great for starting seeds and cuttings, and you may even be able to grow some lettuce with them. (I grow orchid seedlings, pleurothallid orchids and vegetable starters for the spring under fluorescents). But there poor for plants that need lots of light to fruit or flower, as well as for tall plants. High Pressure Sodium works well for these especially the Son Agro. I used one this winter and was very happy with it. But beware of the heat generated so water your plants well.
