Its time for me to replace my bulb. I don't have much experience with different bulbs so I thought I would ask RC. I want to grow sps and like the blue look. It seems that there are not many 400w DE bulbs when looking at marine depots inventory. I plan on supplimenting actinic. I am not sure if I will use PC or T5. T5 seems to be more popular though. Any recomendations, research sites, or places with more DE bulbs selection would be appreciated.
