Part 2 Making tiny greenhouse fittings on 3d printer waterproof. Drip line started. Zone 8b Canada

CA glue or Krazy glue will seal porous 3d prints so they can hold more pressure. There are lots of valves pre made on thingyverse stl site.
I am eager to get the humidity up on this new greenhouse so printed a 4 way barb for misting and drip feeding plants. After more thought I think an option for winter is foam insulate the tub and add a 50w or 100w heater on the timer to keep the water warm. More surface area than maybe the 3" 100w heater fan unit?
