Hey, I just got a 400w digital ballast, (Digital Greenhouse, from HTG supply) and it's making more noise than a normal 175w metal halide ballast I had that blew. It makes about as much noise as a desktop computer...if not more. Is this normal or should I shut it off and call HTG supply on Fri, (as I doubt they'll be open tomorrow)? It seems to be running fine and the plants are loving it, but the amount of noise, (when it claims to be "whisper quiet") is worrying me.
