Led color combos for fresh planted tank

jt41time · 02/20/2017, 11:04 AM

I know this is basically a reef forum, but alot of us rUn a fresh tank also, so I'm posting this....

About to build a 30 led (Mabe less)hood for a buddy. Going to have 20 to 25 5 watt leds 8000k. Then I want to supplement with some other colors for growth and look. I have searched for a good combo, but nothing really comes up.

2 meanwell 60-48d (already have them). 15 of the 5 watts will be on 1 driver and the others will be on the other.... so we can mix with a knob.

15 5w at 1.3 amp is roughly 4.42w. Like to underdrive.
5 5w on separate driver and what ever other colors I should have. I will drive the 5w left overs at whatever the current is for the colors....

Now, what colors for the rest?

I'd add some high CRI warm white to balance out the 8000K white. If you had more channels, I'd perhaps think about some lime to make the colors pop.

For planted tanks you want to shoot for about 5000K. Buddy of mine had a custom reefbreeders layout for his planted tank. Eyeballing it, there were more greens and reds. Warm whites rather than cool whites. Plenty of blues still.

So im looking at

5 watts -
10 6500k
5 3500k

3 watts -
4 royal blue
4 red
3 green

15 x 4.4w = 66w
11 x 3w = 33w
total = 99w over a 4ft tank...
