I bought the equipment for mine from Amazon , used the Inkbird controller, and old alarm panel box, a relay, one outlet, two switches for the outlets, a couple of inline fuzes, and a small switch for the controller. I used YouTube to research the build for the controller box, there are a lot of good videos and some even provide links to the wiring build. I bought the rims tube, temp well, and heating element from brewershardware.com.
