Buying a 400 Watt hps

  1. I figure that I buy the 400 watt hps instead of the 200 watt for more yield.

    I was planning on buying a 4'' vortex fan rated at 172 cfm I think.

    Would that be enough fan power to cool down the 400 watt hps light?

    My grow area is about 2 x 2 x 4.

    Also there is no place I can vent out to from grow room. My cab sits in a place under the staircase and there are no airways on or out of the area. So I thought that venting to outside my cab but still under the staircase would be good enough.

    Will it?
     
  2. You will fry your plants with a 400w light in that size space and no ventilation.
