    If it's a red reptile uv bulb it'll increase resin production

    If its actually red it won't help anything, its out of the plants spectrum. When people refer to the red spectrum they mean between around 2k and 3k in color temperature, not actually red CFL's.

    You should be using CFL's that are around 2700k for flowering, as the redder spectrum may help the plant flower.

    A red light and a red spectrum light are 2 very different lights...a plain red light is prolly useless..

    Daylight is 2700k and soft white is 6500k, or something like that. Soft white is for vegging.
