I use 2 Coralife 175 MH 's (I use these because there spectrum starts out
fair and stays fair on the color shift, this is true ((good MH's start out
good and go bad on their color shift)) and am justifying bying a bad product
to myself) and 4 36" 95 watt vho URI actinics, the actinics are on aprox 12
hrs a day and the MH is on aprox 8 hrs, with everything on the color is
beautiful, IMHO this is a good combo.
