Hi! I'm trying to set up a community tank with plants and have purchased most of what I think I need. The whole lighting thing is confusing me and am wondering if someone can help me out a bit. I have a 46g Bow Front that is 22 inches deep. I want to grow some plants with the fish, but not go overboard. My LFS is suggesting I go with a Haden GLO T5ho 36" Single. Will this work for low light and medium light plants? Or should I get the double? Any input is greatly appreciated!
