What color bulbs is everyone using? Do you get good coral growth?
Would really depend of what you are doing with it and how many bulbs, are they supplementing MH or LEDs ?
It’s a 4 bulb fixture. No other lights.
4 Bulbs make it hard, I was use to 6 and 8 when I had T5s
But if I had to do 4 T5s
2 ATI Blue Plus
1 ATI Coral Plus
1 super actinic
I have 2 MH with 4 T5’s going down the side.
2 150 MH 10,000
2 ATI Blue Plus
2 ATI True Actinic
The Blues and Actinic offset the 10000 MH.
