Shango, just FYI, actinic emphasis the blue spectrum which penetrates 
the furthest into a water column. Based on literature I have read the 
blue spectrum by itself is not the greatest for plant growth, so its 
good you are combining bulbs. Its unfortunate that there aren't more 
varied color spectrum bulbs in compact flourescent group as opposed to 
the "standard" T8-10 bulbs.

Does anyone know if there are any CF bulb companies that produce 
various bulbs which emphasis specific color spectrums?
