5,000, 5,500, or 6,700K? I am planning on getting a 2X55W kit for my 29-gal. Should I go with a mix or should I get the same two bulbs? I am looking for more opinions and feedbacks, rather than one distinct answer cus I know you guys would probably tell me it's up to myself to get whatever I want So yes, I am looking for personal preference/opinion, as well as experiences on which bulb grew plants better(Or is that another personal preference;P). Those sort of things. Thanks!
