I have three bulbs, two @ 6500K and one @ 10,000 (full spectrum). Would it be more beneficial to the plants to have this mix, or to have all three bulbs @ 6500?
Thanks!

Any mix would be fine (or you could do all 6500K or all 10,000K....

Whatever looks best to you. Between these two Kelvin temperature, it will not really matter to the plants.

I would just use what you have and switch them out later when they burn out.

I use 5000K bulbs and have no issues with growth.

10,000k are more blue in color. 5000-6500 are closer to more full spectrum frequencies of light.

So are full spectrum bulbs purely aesthetic? I mean, they don't offer any benefits to plant over 6500
Technically, I think light manufacturers use "full spectrum" to mean that the bulb will simulate natural sunlight, which is usually 5000-5500 Kelvin.

If you buy these bulbs, plants will not do inherently than if you were to (say) use 6500 K bulbs.

I personally find 5000 K bulbs to be too yellow, so I use 6500K bulbs. Some people use 10000K bulbs, but I find them too blue, so it is just a matter of personal preference.
