leds to grow cheato

[mark]

I'm growing, along with lots of others, Chaeto with a 23W CFL. Would think a started point for the number of LED would be what would give you the equivalent wattage.

i'm building one right now-using a 50 watt driver -2 heat sink fans and red,white,blue and royal blue 3 watt leds-i'll be using 15 leds with 60 degree lenses.i am going to use 5 red ,3 blue and 3 royal blue,and 4 white

+1
So that would be 6500 deg Kelvin

my CFL is 6500K and bought some replacement LED bulbs for my range hood that are cool white (6500K), wondering if you can get by just on white LEDs (not needing to mix in reds and blues for Chaeto growth)

no idea-but i've read that the red colour helpps with plant growth-that's why i am going to use the 5 reds
