So I have my rack built and ready to be wired up with flexwatt. I was wondering if anyone knows if running one long piece through helps ambient temps within the rack more that multiple strands. I see the pieces going down the sides when it's snaked through and wonder if that helps. The rack is a fully enclosed insulated melamine rack with 6 shelves. It's insulated with foil tape and I have reflectix if need be. I also have channels cut through under the flexwatt to heat the tub underneath as well.
