Re: [APD] Bushier Plants

["S. Hieber" <shieber at yahoo_com>]

The diff in penetration that makes blue light relevent to reef tanks is several to over a dozen feet of seawater. The one-half to two-foot depth of most aquariums won't make much diff on penetration. Also the diff is blue light between most "medium to cool" white lights and the high K temp bulbs is relatively small -- sometimes it's just less red and not more blue.
 
Actinics sometimes just leave out a lot of the red light so using an actinic can make you plants behave like they are under a slightly weaker bulb, not that they have anything against the wavelengths coming from so-called "actininc" lights.

November too cold? Too hot? How would you like to spend part of November in San Francisco?

So I used to have the GE 9325k bulbs on my tank and I switched to 6700k  
bulbs.

Does this mean I would have had bushier plants with the 9325k bulbs than  the 
6700k bulbs and if so would it be very noticable?
