I have a lumatek digital ballast that can dimms. What is that used for? If i can use that feature when should it be applied?
I have the 600w Lumatek e-ballast (digital, like you're talking about)... I had mine dimmed to 240w, and 400w when I started my seeds. From my understanding starting off you dont need/want the brightest light possible, hence why ppl utilize CFL's to veg sometimes.
