My 5 month old 400 watt digital ballast wouldn't turn on MH bulbs, but has no problems with a HPS. The problem with that is that it's my veg tent with 3 week old clones. I emailed vivosun and they emailed me back within half an hour. A few emails later a new replacement ballast was being shipped to me. I got the ballast during work today, I was so excited to get home and set up the proper light for my girls! I opened the fuckin box and it's a 600 watt ballast! I have 400 watt bulbs! So back to emailing them I guess.
