InvisibleM, Widowmaker, Dr Stickerdick....I'm looking to you guys for some advice here. All the info so far has been great, now I'm trying to apply it. Keep in mind, I have no clue when it comes to electrical, however I have a friend out-of-state that could possibly help me. So I have 2 electronic ballasts from NextGen. 600W each. I bought an AM/FM radio and tried it out. I can stand within about 2 feet of the ballast and get about half-static. I only get full static if I essentially tough the radio to the ballast. If I go down the hallway to the living room, it fades to almost nothing. Very minor if noticeable. Do you think I'm gonna have issues? I am in a condo so I have neighbors that aren't far, but I still feel like once I'm outside the apartment it's virtually gone with my radio. I'll have to test with both on, that was just with one ballast firing on high. I doubt I have grounding issues, as the whole ballast is metal. Or maybe I still do? Hopefully this info is enough for you to pass on some advice. I really need to get these plants flowering, they've been in veg for 3 months. But wanna make sure I'm safe first. So main questions if I haven't lost you...How much interference is enough to get noticed(I'm sure the electrical co has sensitive equipment)? Do you recommend that I try to use the insulated wire like InvisibleM did? Any suggestions are welcome and appreciated. Peace. DrD.
