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.
