CFL... 6500k, or both 6500k and 5000k

I just bought 4 32w t8 bulbs at the store, and accidentally grabbed two 5000k along with the two 6500k i meant to grab. Would it be more beneficial to use both the 6500k and 5000k bulbs? Or should I take the 5000ks back and use strictly 6500k. I understand plants need a broad spectrum of light, but with 5000k and 6500k being so close on the same end of the spectrum, I wonder if it would be better to use all 6500k, which I initially intended to do. Or should I even mix in a 2700k lamp? These lights are going to be strictly used for vegetation.

My first post! Thanks in advance for any replies!

Go ahead and use both, maybe even getting a couple 2700k's.
When I was looking for my 6500k's, I was told that the 5000k bulbs work just as well, and they did.
I also had some 2700k bulbs, planning on my next grow, so I threw those in too, and it worked great.
P.S. Welcome!

Sweet, that's kinda what I was thinking. Thanks again!

Good luck, keep us posted with your success!

hahah you don't need anymore answers. Nail smacked head in. I'd just add you should use 3:1 blue to red! Worked out for me!
