I'm glad to see that you're still lurking around these parts. I'm using a few 50 watt RGB leds to bring out the "reds" in my tank. I'm also blasting my Ludwigia Inclinata var. "Cuba" with an additional 100 watts of Warm white just as an experiment to see if it will get any more "blood red" than it already is. Lol
Hey O2! Yeah, my school year gets pretty hectic, so I try to get back in the swing of the forum in the summer - when I have the time, haha...
Nice to hear you are having success with the warm whites - my mix wasn't producing the color I was looking for, so I added some red as well. It was a little, but the difference in growth was noticeable.
