Hi petflora, long time. hope all is well. I bought a slightly used SpydrX Plus with 8 bars on the super cheap and it has the 3.5mm jack dimmer input. The local hydro shop said any 0-10v dimmer would work. I bought a 2 conducter 3.5mm jack and a cheap amazon dimmer. wired it up and when I plug it in, the light shuts off. unplug the jack and fires back up. I REALLY don't want to pay big bucks to control this one light. Anyone?I have an original which has one driver that supplies all 6 bars individually. This allows to unplug the ones you don't need, as in for veg stage
