Don't know what size the cab is but I'l guarantee it will be hard to beat 3 - 4 Flouro lighting fixtures, usually the garage ones that do 2 bulbs. Put Gro Lux bulbs in it and you'll be impressed with the results. That is what my current recomendation is to VEG. If you have a smaller space then try the 2 foot gro lux bulbs and let me know what happens.
