6400K vs. 6500K

[andyjs]

Does it make a big difference for plants? I just got a CFL desk lamp to light a little nano planted tank. It didn't say what color bulb it came with, so I also ordered a replacement 6500K to go with it. It came today and has a 6400K bulb in it. I'm guessing it won't make that big of a difference?

If that's the case, I'll just run the 6400K as long as it will last and keep the 6500 as a spare.

I'm sure what plants it will house quite yet btw. Probably mainly mosses, but I'll probably try others as well

Nope. 5000K to 8000K is where you aim for. 6400K vs 6500K vs 6700K is probably not going to make a bit of difference.

you wont see much of a difference within maybe even 500-1000k with any light source unless you have them side by side

 

[rockhoe14er]

doesn't matter at all.

The difference is negligible. Typically, 5000K-10000K daylight bulbs grow plants just fine.

Eh, I don't see much difference either...

 

[andyjs]

Just what I thought, thanks!

doesnt matter though the lower the K rating the more yellow everything looks.

I am sure that the difference is so small even a meter will hardly pick it up.
