That is only one plant, very bushy, I do not do as much defoliation as others do. I'm using four 55 watt (actual wattage) CFLs, two at 2700K and two at 5000K. I like the CFLs, less expensive, less heat, and they last a long time (I've only had to replace four in the last two and a half years (three burned out and one just got dimmer than the rest and I replaced it anyway). I'm using aluminum foil on the walls and I believe that is what is responsible for the 'bushiness' of the plants, plus it keeps the aliens from taking control!! LOL!
