I have found that my local hydroponic supply store has some items cheaper than I can get online or from more traditional sources.. I have found roll coco fiber panel I use for background for $2 a foot, 3 foot wide thats pretty good, they have the compressed coco bricks for a lot cheaper that the pet stores and I have had no problem with them. They carry a varied assortment of lighting, but those are mostly very expensive, and I am very cheap. Hydroton, or Gro-rox can be had at a decent price, and they will sell it by the quart Also water pumps and natural organic fertilizer. Any one else have some secret suppliers out there?
