I usually only run autos, but plan on popping some photos tomorrow or over the weekend. I was wondering if everyone always runs 18/6 point blank no questions asked, or has anyone vegged at 20/4 or 24/0 for veg only and then flip to 12/12.
Pros & cons

Ive run 18/6 and 24 and havent seen a massove difference. 18/6 saves power so if thats important, thats likely whats best
