I will be getting one of the Exo-Terra Extra Wide/Extra Tall tanks (36" length, 18" width, 36" height) and I was wondering how many T5-High Output fluorescent tubes I should use for lighting. I've been looking at a 2 foot long, 4-tube fixture from a local hydroponics supply place. The fixture comes with 4 6000k bulbs, but I am going to swap out 2 for 3000k to get a more natural spectrum.
Due to the height of the tank, my plants will be between 1 and 2 feet from the lights (depending on plant height). With the set-up I am describing, is this too much/too little light for Nepenthes? I have the option of getting a 6-tube or 8-tube unit, but I feel that would be overkill.
