Oh I forgot to tell you guys...
Last night before I went to bed I opened the grow room a bit so more fresh air can get in, there is no problem as the room is pitch black...
but suprise suprise... when I opened the grow room, I could see light inside, really really faint light, I couldn't understand where it was coming from...
so I bent down to investigate and I saw all the led glowing....
i think this explains the hermie, if not other things too!
I have contacted the support and they are sending in a power supply replacement, until it comes I will be unplugging the unit when the unit turns off so I have complete darkness...
