Hello, first post here.
I have been reading and learning a lot thanks to everybody here.
It seems that everybody loves the Finnex and build my led lights.
I purchased a Finnex planted+ for my first tank (29 gal. bowfront) thanks to good reviews from everyone here. seems like the light is working very well.
It is now time for me to purchase a light for my new 125 Gal. tank.
Seems to me that my best option for medium light on a tank this size is a build my led light. At least for the money that is.
On that note i have been trying to read around and see what nm light that plants use the most and a way to also give a good visible light spectrum at the same time. Over at the GE (General Electric) web site, they say that 612nm (if memory serves) and 660nm in the red spectrum are the most used by plants as well as 470nm in the blue. They also suggest that ultra violet light plays a role in helping plants utilize light better. It also sounds as though the red spectrum being a higher frequency produces more photons and therefore needs less light to accomplish the same thing as blue light since blue is lower frequency and therefore less photons.
So i included two 470nm blue and one each 615nm and 660nm red and one 405nm IR led and the rest 6500k. this seems to give me a 10232 CCT, and 130.94 micromoles/sec.
All this being said I played around with their do it yourself spectrum calculator and came up with what seems to me a good spectrum but i have no experience in these matters so i thought that i would post here and see what you smart people thought of this.
here is the link to my spectrum.
Thanks for any help.
