    It depends on what you are growing. Yes, they have all those problems, but they ensure that the light gets down to the base of the plant on those taller plants(Nepenthes, tall Drosera).
    Your grow area will be fairly large, so you will have to use a ultrasonic humidifier or something similar to make up for the humidity loss.


    Cheers,

    I prefer the compact flourescents which are VHO and self ballasted. To top it off 65wtts = like $.05 a day to run. Mine color the plants up very nicely and I can touch the bulb even after hours and hours of running. (low heat was the point)

    How do you run florescents on a VHO ballast? Do you just buy an extremely high wattage ballast and run it or what? That would be quite expensive wouldn't it. Darn now you've got me interested...and just after I purchased a whole load of bulbs and ballasts... [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_n_32.gif[/img]

    just run an NO lamp on a VHO ballast. easy-peasy. they only last about half as long and run hotter though.

    How do I identify VHO ballasts?

    The heat is no problem, I'll put fans on.

    it should say it on it. i bought mine awhile ago at marinedepot.com i dont think they have my model anymore. it was like 175 bucks or so for a retrofit kit that including all the wires, ballast, reflector, and waterproof endcaps. a good deal IMO, even though thats expensive for lights.

    i have to overdrive NO lamps on a VHO ballast because i can't find VHO lamps with the right ends. real VHO lamps would be alot more efficiant.

    Sorry guys but....what is a "VHO ballast" as opposed to a regular ballast and a "NO lamp"?
