    and they are enclosed in a case so no uv ever reaches anything that doesn't pass through the filter.

    [QUOTE]they do use ultra violet lights to kill off bacteria in fish tanks, but those are just really massive amounts of light.


    Yes they do, but the lamps most certainley do not produce massive amounts of light.
    The highest wattage UV lamp Ive used for sterilization was only 40 watts. Exposure and thus destruction has more to do with duration
    and the distance of the particle from the lamp.
    Most UV sterilizers for fish move a small amount of water over the lamp housing relativley slowly.
    I find it pretty unlikely one could do damage to a healthy plant with a little reptile bulb.
    Peace

    Nice ceph, Brian.....can't argue with emperical results. What is your lighting setup?

    For myself, adding a UV bulb would necessitate the removal of a fluorescent bulb. Since my lighting setup is not ultra-high output (I have 80W cool white fluorescent light over 2' x 2' area or 160W over 2' x 4' area, most plants 3-5" under lights), my main concern would be replacing 1/4 of spectrum used for photosynthesis (i.e., 1 cool white bulb) with a UV spectrum that is used largely for non-photosynthetic processes. Thus, while my plants would (perhaps) become better colored over time, they would be slowly starving due to inadequate photosynthesis....at least that's my fear.

    I don't think this would be an issue for those growing their plants under very high output lighting, but it may be for the rest of us.

    This is why I look forward to Elgecko's experiment. Any thoughts?

    I just use 4-40 watt fluorescent tubes. A combination of wide spectrum and cool white works well. I don't think you need special tube just for UV.

    I'm always surprised when I see pure green cephalotus, because mine always turn dark, even if they are grown from a distance from the lights.

    Brian_W,
    Your plant does look very good.

    Here's my nice green plant.



    Although you are using, double the light output then I am.

    Thanks for the info. I take it you're satisfied with the results. Do the plants you acquire get better/enhanced coloration over time?
