most people will tell u to get big high watt cfls, i'll give u my opinion.
get around 10 - 16 of the warm white 23 watt (100 watt incandescent) and a bunch of those Y splitters. try to surround your plant with light and get them night and close. then keep an osculating fan on the plant to keep the lights and plant cool.
cfls only really work very close to the plant and if u surround the plant with them.
