The Hydro store has these 600 watt digital ballasts - but they aren't switchable- the guy at the store says they use a bulb that has a spectrum somewhere between MH and HPS that'll work for both veg and flowering. They're pretty expensive ($500-$600). I'm wondering if this type of digital ballast and bulb really has the range that he sez it does and if it'll significantly effect yeilds. I think he might've said they don't make switchable ballasts in 600 watts- they only make them in 400 & 1000. Is that true?
