Wrong power cable in my LED light: still light when switched down off.Have you ever made this mistake? My second harvest was someway worst then my first. Sure I did some watering mistakes but during my chores in the room and in the tent, I found out. I used a random power cable on my PAR LED lamp so when It turned off still had some light on. Bang!Week 16
