Does anyone have any experience with Osram lighting as pertaining to the growth of aquatic plants? I have read a number of technical articles (The Krib, newsgroup archives) and would like to receive information of a more practical nature. I am considering a fixture consisting of three (13W, 5000K) daylight bulbs and 2 (9W, 7100K) actinic bulbs mounted on a 40L tank. Thank You.
