if a person where to make a grow box that was 42" wide X 32" deep X 60" tall would one 600 watt hps light be enough to do 3 plants, i know this may sound stupid but this person has never grew anything inside only outdoor. also for ventilation how much air it intake?? and if the 600 watter was not enough could cfl's be placed on the side of the plant to promote side growth..
