I would highly suggest that you only run the 2x24 t5ho bulbs. This is more than enough light to grow any plant.

Actually the 6500k bulb has more green spectrum which the plants can use more of. When compared with a lux (cant remember if that the right one or not) meter the lower k bulbs provided more output.

Thanks for helping Bobby(ham86) out. My kid brother is always asking questions. I wish I would of had that much confidence at his age. And access to the internet.

I used to think 6500 K lamps were too blue, but now they look about right to my eyes.

If each of your lamps has an individually corded ballast, you can put each one on a separate timer and have a multi lamp midday blast by overlapping the times. Saves the daily hours on each lamp tube and they will last longer.

Never argue with a fool. Onlookers often can't tell the difference.
Growing older is mandatory, growing up is optional.
My advice is free and worth every penny.

I totally forgot to mention what I run on my tanks for lights. on my 20 long I run a 10k 420nm (actinic) combo I think it looks great honestly.

on my 125g I run 3 54w x 67k N.O. fluorescent (over-driven) and one actinic 110w vho. (icecap 660-009 ballast)
my 125g is 24 inches from soil to surface. this combination allows me to easily push photosynthetic light all the way down to the substrate. at about 2.17 wpg.

After reading this thread I went out and changed the lights on my 25g to 6700k and 10000k, the combination of the two makes a really nice bright ( but not overpowering) light, it also makes the greens of my swords appear much more vibrant.
