Hey OldGrower,
With your ammeter are you using a shunt by any chance?
When i hook up my cheap ebay ammeter, for some reason it causes the LED driver to go to 1800ma (when its a 1400ma driver) and also uses like 100w more from the wall.
Built my system from stinkbud design and have made modifications to suit my own style of growing.
Have not been active on rollitup but plan on returning to spread knowledge of my experiences an style.
