Vivosun digital 600W HPS + MH ballast
@dbrn32 is who you need to tag my friend
I’ve heard it changes the spectrum.
I’m curious as well I have a 600 hps air cooled in a 3x3 and my light is 70 inches off the floor. Stays 78-80 degrees though. I’m thinking about getting a bigger tent a 4x4 I think would be perfect. Unless you change the ballast you still drawing the same juice so might as well use the max space you can in my eyes
You can safely use dimming on ballasts that are equipped with dimming capabilities. There is data suggesting wavelengths emitted will change some, and using super lumens will shorten bulb life.
