The rods are not a big deal and you don't need a lot of them. Just to get the honeycomb off the bottom so that the air can flow down and around them. Space the rods 4" apart and 90 degrees to each other. You don't need to have them 1/4" in diam....use 3/16" or 1/8"....use what ever you have.
Hope this helps.
