    I think the recommendation for 20 gallon tank is a 4 tube fixture or the use of CFL's.
    For my 20gal long tank i use a economy reptile hood which has 3 fixture for screw in bulbs.
    I use compact flourescents in these 3 slots, totaling about 80 watts. I then surround the ENTIRE tank with mylar so that the light reflects all around the plants!
    Hope that helps.

    no, i don't have a fan, but do leave a crack for air. The tank does get quite warm from the heat of the lamps, about 90 degrees. But this is ok as i grow the D. petiolaris group. the mylar came from atwaterhydro.net at $22 a roll. Best price i could find online.
    The plants were noticeably happier once i put the mylar up!
    Hope this helps!

    Mylar is a trade name for a reflective poly film. It has very good reflective properties, better than aluminum foil.
    2mil thickness is best as 1ml is pretty flimsy and is hard to work with.

    I recommend that you should use FluoreX Fluorescent Flood Light from Lights of America. Grow all my D. Falconeri with these lights. These are very cheap and great grow light's.
