I use the home depot drip line, its brown/tan color and its in the sprinkler section. Its from like rainbird, or dig, or something. It comes in 100ft rolls and its like 6" rolls. Its 1/4" tubing. I also use the female pipe thread to 4 way barb peice and split it between two buckets pulling out the plastic screen, cuttings out the screen part and putting it back in to still be used as a washer to prevent leaks. Every month I take the lines off and replace them as preventative measures. I use GH 3 part, floraliscious bloom, and grow, and dyna gro protekt. I will soon be adding Botanicare cal/mag. Another option to that lava rock is 40%coco coir/60% hydroton. Many people use this to avoid having to use the chiller. I would still use a chiller for the resevoir though as it will keep bacteria from growing, keep it at 68-70 degrees. Here is another option for cloning large scale if you go vertical. I think you are talking about coliseums, so here ya go... ofcourseif you meant vertical bulbs then here you go anyways.
