If you are still using a copy of the 2007 Sunlight Supply catalog consider updating to the newer 2008-2009 edition. It's been available for some time now but we finally received the most recent edition and felt it was worth passing the word along. These catalogs make a snappy reference for prices and an excellent starting point for brainstorming DIY projects. For that reason they are very helpful to have around, even if you never order a single product. Copies should be available at most hydroponic stores or you can request one directly from the Sunlight Supply website.
