Veg & flower on same bulbs? Help ??

[daihashi]

Hi, it costs e alot to get CFL lights and i was wondering if I could veg on my 6 6500K 1450Lume CFL's and then flower off the same bulbs but change light to 12/12?

Would that work or would i have to get 2700k bulbs for flower?

2700k bulbs would give better results but yes you can flower with 6500K
