I did a search on this but came up empty handed, I am going to run 12/3 for my ballast to bulb line, what is the length I should keep it under? I would like to run it 20' max, but but hear mixed reviews on this from people, some say your bulbs wont be as bright, some say its fine. Any insite on this, DierWolf? Also, would love to find some info on wiring a flip/flop ( wiring two rooms with one ballast) , I know there was one posted with the hid write up, but there is no real insite on the acual relay itself, and wiring of it. Thanks
As long as you have good elec cable I don't think 20ft would be to much, in fact, I'd bet some of your big greenhouses have there balast even farther away.
