Right now I am using a 40w 10K premium daylight and a 40w Ultra-Actinic. I'd like to replace the Ultra-Actinic with something else as it's not really benifical to my plants (At least that's what I hear, even though if you read CSL's web site: Ultra Actinic Provides the necessary energy for activation of photosynthesis in chlorophyll A and chlorophyll C) ?!?
But which spectrum to go with is my next question.
5000K, 6700K, or 8800K?
What are you thoughts?
