Which Light Wattage To Buy?

  1. Ok, so I am almost ready to buy some lights for my tent. I am growing in a SeretJardin DR120 which measures 46" x 46" x 78". 
    (or close to 4ft x 4ft x 6ft). I will be buying lighting kits that come with a ballast, a cool tube, a bulb, and an air-cooled rectangular hood. I will be growing 4 plants.
     
    I understand that when using an air cooled hood, you lose quite a few lumens from your bulbs. Since my tent's width and length is pretty big, I don't think one light will be enough to cover all four plants, so I will be buying two separate kits so each bulb will evenly cover two plants. My question is should I go with two 600w bulbs, or two 400w bulbs? I'm sure most of you will think two bulbs is overkill, but I am going for maximum yield, and like I said before, the air cooled tubes will take a lot of lumens away.  

     
  2. Buy two 600 watt lights if "too much light" is the only thing stopping you. It won't be too much light, plus you can always raise them higher if need be. With my air cooled setup I never get burn from my 400 watt lights, even a few inches from the bud for days on end! I have had a CFL burn my plant where it touched, and my LED will burn up to about 8 inches away.
