    What's the best, most affordable lighting setup for tall plants like nepenthes. I'm talking around 2.5 feet high. Thanks.

    High pressure sodium or metal halide.

    I think the HPS is a little cheaper and a little more economical to run but I prefer the metal halide because the light is whiter looking.

    Is that a Nepenthes in your pocket or you just happy to see me?

    Do you know any good places to get those from? And are all of the bulbs the same, or what type would be best? And would heat from the lights be a big issue? Apreciate it.

    I would recommend metal halide lights using the new ceramic-bulbs. Best light color is propably 942 (4200 K, very natural light, a 150W bulb gives you about 34000(&#33[img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] lumen and this with excellent spectrum !
    High pressure sodium lights (at least with high power)are more effektive in lumen/W, but less effektive for photosysnthetic rates.

    Ok, so how much would you expect to pay for the metal halide light fixture, and the bulbs? And how far away should the lights be from the growing point? Thanks Tony and Martin [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img] .

    ahh, I'm sorry, the output is 14.000 lumen of coarse, not 34.000. This would be impossible :-)

    I bought an used 70W halid lamp (HQI shop light) at ebay for 20 Euro and bought a new ceramic "bulb" for about 14 Euro.
    Not really expenisive.

    if you run a search on yahoo you can find an economical 400 watt halide system for under 200 dollars shipped from any hydroponics supplier. The pendant hangs from the ceiling and I would say about 3-4 feet from the plants to be safe.
