Cfl Daylight bulbs as grow lights?

[kwarren]

I saw an orchid enthusiast's video on YouTube and noticed he was using the cfl daylight bulbs as a supplemental light source. This bulb gives a slight bluish cast of light and I'm wondering if it truly is beneficial and can be used as a substitute for the incandescent plant grow lights which uses much more wattage. One brand of daylight bulbs states on the box that the light appearance is listed as 5000K on a scale that measures warm to cool light. Another brand has a daylight coolness of 6500K. I do not want to use florescent fixtures with grow tubes, so the cfl daylight bulbs seem like a wonderful idea. Does anyone have any information or uses this type of bulb as an efficient substitute for grow lights? I would really appreciate anyone's knowledge or experience.
