Re: [APD] 9325 K GE Bulbs

Good points with which I do not disagree. But I would add a
that most actinic types of power compact fluorescents
probably yield plenty of light in the blue spectrum, which
plants are "hapy" to get, but the overall amount of light,
due to the lack of light in the yellow and red area of the
spectrum means that such bulbs are not as effective, watt
for watt, as "broad spectrum" or "triphosphor"  or
"daylight" bulbs.
