I am trying to get my grow room together and right now I am working on the electrical (which is my least favorite thing to do but I get by) What I want to know is can you wire a Rehostat to a duplex receptacle and plug your inline duct fan into it and have a proper speed adjustment? I know the question may be stupid but, what is the difference from doing this and buying one from a grow store that basicly does the same thing. I did notice that the one on line has a 15amp fuse in it. Maybe this is the difference between it and wiring a duplex receptacle. I don't know. I just need someone who knows electrical to please give me an ansewer. As always thanks in advance. Jim
