i have 3 (t-8 ) fixtures each holding 2 bulbs 5000k.so just any old 4ft. bulb???
get the t8's.$20 each.they are better and brighter then the t12's and are electric ballast not magnetic witch means they run more output with less watts. do a google search on the t8s you will see. i use a 5000k bulb thats gives a cool spectrum for the veg. the bulbs cost me $5 a piece. you will not be disappointed.
