I am now planning to put my nepenthes highland tank (130,50,60) in my basement. It was far to hot in the old room. I am a total newbie to artificial plant lighting.The plants their pots wil be at 20 cm's of hight. So that leaves the pot surface at about a 40 cm from the light(s).So i have read both sticky's about plant lighting but i am still quite confused about the whole issue. Because the tank is in the basement it won't get any sunlight at all.So now i was wondering ; should i use metal halide lamps or fluorocompact tubes? Isn't a metal halide also quite expensive to run?Wel any lighting info is greatly apprecieted.
