I have a 10,000k Metal Halide lamp and ballist that was used on a Marine tank for corals. I am wondering if this is suitable to use to grow Nepenthes in a lowland tank. How far should these lamps be from the plants because I didn't get a manual for it and it was custom made. And I don't want to burn the plants.
I am also using fluorescent tubes such as powerglo and I have seen the aqualux fluorescent tubes and they have 10,000k written on the packet and claims to promote growth for plants and corals as opposed to a grolux fluorescent tube that says it promotes photosynthesis. Which is the best to use and what is the exact spectrum (in nanometres) *that Nepenthes require to grow efficiently?
