Sorry, I didn't remember. Should have gone back and looked.
If you keep em short in veg I think you would probably be okay with one of the 240s. You'll get better light coverage from a rectangular fixture than the round one and enough watts to penetrate the canopy well. I've got a couple super autos under mine right now that are over 3' tall and the lower buds are just as big as the upper ones. LEDs in small, well lined areas do very well. I think you'll be fine at 10 - 12" above the canopy as long as your getting good reflection.
