Efficiency of 2 boards Vs 1

  1. Was hoping someone may be able to give some insight I notice the 288 can veg a 3x3 I currently have 2 running in my 3x3 and wondered is two dimmed to 160 watts the same as 1 single board at full power in my 3x3....also if anyone has any guides for hanging height and dimming for veg and bloom would be much appreciated..
    Thanks in advance blades

  2. Yes running these boards at lower power does increase efficiency.

  3. I'm currently running 3 separate 4x4 veg tents, each tent has 4 plants and are powered by a single QB288 at full throttle. They seem to be enjoying it.
    Check for yourself here.
  4. Oh nice results...yeah just noticing a fair bit of stress now so dimmed drivers in tents to 180 watts see if that's low enough...I bloom under 4xqb288 2 of them r-spec and they seem to do well just the 3x3s giving me grief

  5. Get a $30 lux meter (google lx1330b) then you know exactly how much light you are giving your plants.
