Which ballast for 400w radiums
I can't decide which ballast would be best for 400W radiums. From what I have seen online, I like the SunAgro PFO HQI but I understand I would then be replacing bulbs every 6mths, I like the Sfiligoi, also HQI or I have read Lumatek or Galexy Eballast would also be good choices. Are all of these ballasts available in Ontario?
If anyone has any pictures or comments that would help, it would be appreciated.
