True about the penetrating power. I forgot to say I was doind small plants. veg for 2 weeks and then flower. Using a SOG. That way all the plants are evan and small so the light can always stay close. This way I dont need the penetrating power as much. You still think I would be missing out. Oh and I already have the 1000's

I also would have a smaller vent but really trying to save money on the power bill and keep the heat down (for the ac bill).
