    Dryer Outlet Grow Light Controller DIY

    Though this is old, I want to build the same thing. Only thing is that I have a 4 prong dryer outlet (hot/hot/neutral/ground) instead of the older style (hot/hot/ground). I'm wondering if you can just cap off the 4th(neutral) wire and do everything else the same.?? Anyone else done this yet?

    Anyone know if you can use a 4 prong dryer cord instead of the 3? Also, where you would connect it? (hot / hot / neutral / ground)
