Hello everyone new here and I was just wondering if anybody could possibly help me with a question I recently acquired an original phototron hydroponic grow box and it has the black cord that goes to the lights which I understand but it also has a little brown cord that goes to the bottom of the unit and I was wondering is it a built-in heater or is it a hydroponic pump of some sort can someone please tell me I'm going to post a couple pictures
