If you have a Digital Greenhouse Ballast I have a question for you. Having never heard a digital ballast before I was surprised with the buzzing noise it made. I know traditional ballasts can be noisy as all, but I really expected this to be almost whisper quiet. I can hear the cooling fan, but there is also a very strong buzzing noise. Is this normal? Or did I get a bum ballast? It is loud enough to be heard from the next room over as a background hum/buzz. Thanks! I know I have seen ballast questions posted before, but perhaps it is just me, but the Search function isn't working right now. Any input would be great, Digital Greenhouse, or just digital ballast. Do they really make this much of a buzzing noise?
