Well sorry to say that my one remaining, quite healthy plant is a dude so I yanked him. This unfortunately means that there are no plants left for my LED grow. So this grow is over, but I can say that the plants seemed to do fine under LEDs with one 42 watt CFL. But it does seem that it is important to place your plants directly under the center of the LED array. Dunno when I'll have time to start another grow, but I'll continue to use my LEDs.
