Silk is right-you need to get a hps ballast to run both Hps/mh bulbs. Just to clear thing up a bit. The higher # of kelvins ie6700k is your blue spectrum=vegg light, early summer sky. The lower k ie3000k is more red/yellow spectrum=flower=late summer sky. Whereami- Its more then just watts and lumen its spectrum too. To get the best bud poss, blue light to vegg, red light to flower. Thats why you go hps to flower. You can use both spectrums throughout-thats what I do. Cfls and floro tubes are the same thing different shape. I recomended the T-5's because I love them and they work great. Mine were cheaper then 150 for the entire hydro kit and light. So really your choice. Vegg w/cfl-get lowes hps security light to flower, whatever is best for you bro. Happy growing!
