i would suggest a 250w Cfl for veg and a 400w hps for flower that would handle 6 decent size plants in a 1m square area..an oscillating fan for air movement and a means of exhausting the growspace, preferably the size of the room every 5mins or so..as for fastest grow cycle hydro/aero/bubbleponics are ur best options but this does involve a bit more gear and knowhow with optimum ph levels and ec/tds/ppm measurements and such..as well as more power to run pumps/heaters/airstones more risk of flooding, and if thers a power failure or some sort or nutrtional mishap, all the plants in the system suffer..as opposed to hand watered soil/soiless mixes..its really down to how much u wanna spend and what u wanna achieve i guess?? peace jah bless
