Getting my newly built rack dialed in! I am using THG (TGH?) heat tape and an arduino for my thermostat. I used 4" tape at about 2 feet lengths for 2 snakes. Then I taped the edges of the heat tape with metal tape. I also put metal tape on the bottom of the tub for a heat sink like effect. My questions are does that sound like a safe and efficient setup and what does the actual heat tape temp run in relation to the temperature of the hub? Thanks! No snakes in them yet
