Also, what y’all think I should run, 3000k or 3500k? This is strictly for flowering in mind so I’m leaning towards the 3000k, I have a 3500know but thinking that a little more red might make a little difference .

3k for flower is nice.
I'm driving 5x vero29's with the 1750ma driver, but I run them at 1400 using dimmer. Have option to crank it up to 1750 for late flower. Guys are killing it with Quanum boards too. Nice thing is, both technologies can be scaled up over time when cashish available.
