    Something I've been thinking about trying for some time now is getting a reptile light that emits UV rays to use on my plants.
    All plants growing outside get UV rays from the sun. Regular florescent bulbs on terrariums do not emit any UV rays. I often have wondered if using a UV bulb would make any kind of difference in the growth of the plant.
    Has anyone ever tried any of these bulbs, any kind of difference?
    I think in Jan. when I replace the bulb in my terrarium I will get one and see what if any differences I can notice.

    Correct me if I'm wrong but I think I read somewhere that UV rays help combat fungus/mold?

    UV lights not just help control fungus ect, they kill everything living. UV lights are used to sanitize operation rooms, and kill microbes inside the body (used in very small quantitys). So my guess is that if you run UV lights on your plants, they're gonna die (burn up).
    Grown outside, they dont get a lot of UV because ozone filters it in the atmosphere, and even though theres still plenty of it reaching the plants, they're not in the sun for 16 hours you know. Why you think your skin burns on the sun? Thats right, UV overdose.
    So do what you want man... maybe Im wrong and your plants will grow well.
    By the way UV also causes mutations [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img] so maybe you'll get canserous plants that grow like 10' tall lol

    I would tend to agree. UV wavelengths fall outside those maximally used by most plants for photosynthesis, so the benefits of a UV light could be negligable. Moreover, UV light damages molecules (e.g., proteins, DNA, lipids) and metabolic processes needed for life--so many plants actually rev-up their defense mechanisms when exposed to UV.

    But who knows, you may find unexpected results and I, for one, will be interested in your report. Good luck.

    Wow and to think i was gona ask the same question the other day about these bulbs, good to know not to use um but then again ya never know if you can get one thats not as strong in UV and burns cool daylight maybe that wont be as bad?? [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_l_32.gif[/img] I know one thing these reptile bulbs put out far more lumens than the compac's we are using now. The reason for so much UV and UVB is to help reptiles build strong bones and other benifits.

    You guys need to also take in consideration that the kind of UV reptile bulbs use are UV-A/B wavelengths from UV rays. It is only a certain percentage that it omitts to. I have 2 4ft t9 reptisun 10.0 bulbs in a shoplight fixture, lighting my Russian Tortoise. The strength of the UV-A/B is not strong enough to do what some of you are talking about, and not comparable to the full spectrum UV rays from the sun. So I don't honestly know what would happen if you did this. I wonder if the UV omitted from the bulbs would be strong enough to give you any kind of benefit because they are made for supplementing reptiles. My guess would be your plants would decline a little because they aren't able to absorb the UV wavelengths, and will be missing the lumens and wavelengths they could use if you were using a normal bulb.

    I didn't say not to use them, but just suggested that they probably shouldn't be used. That said, I certainly won't use them myself but, instead, will happily wait for others to experiment on their plants!
