400w LED large enough for max 3 plants in a 2x4x5 tent?

  1. Just doing some research into LEDs for my next grow.  I'm currently running 3 plants under CFLs.  Digital HPS systems worry me a little with the RF interference and power consumption.  Could go magnetic ballast, but I am not asking about LED vs HPS in this thread.
     
    Is a 400w LED large enough for max 3 plants in a 2x4x5 tent?  Or would going with 2 x 300w for ~$80 more be much better?
     
    Any info is appreciated.  Thanks.

     
  2. I would get the two 300w LED's depending on the brand.  As long as they are a good brand you'll have more then enough watts for 3 plants.  Now, is the 300 actuall watts or is that whats is just listed at? Same question for the 400 watt LED

    No, I believe the actual draw is closer to 190 for the 300w and 260 for the 400w.
