I'm working on designing the vivarium setup for a pair of tincs and had some questions for more experienced folks regarding watts and color temp. Currently leaning towards the AH Compact flourescent. Tank size is 20 gal tall. I want to ensure healthy and vigourous plant growth of bromeliads to mosses. Should i go with 55 watt fixture? Single or double. Or is 36 watts enough. That seems low to me. Thinking at least 55 is necessary. Anyone have preferences on color temp such as 5000K vs. 6700K Thinking of going with a lower, warmer temp. Let me lnow what you think folks, i'd appreciate the insights.
