Can You Use Blue and White Cfls during Flowering?

is better to use just cool whites or add blue with them?

you want to use the red spectrum, 2700k.

True, definately red is better for flower, but it doesn't hurt to have both spectrums. if it is one or the other though go with the red.

i have two whites and two blue bulbs in there now..so i should get red spectrum??
