I got a 1000 watt ballast from a friend that Says it uses ED style bulbs and has a picture of a fatter looking bulb like a MH. Im pretty sure it is for commercial large grows. It came with one of those huge umbrella hoods that you see in large gros. I haven't seen these before and i need to figure out where i can get them. I did a search on google and i some forums and didnt find much. Or can i just use a regular 1000 watt HPS? any info would help greatly!
