  1. Howdy y'all, have a 2 x 4 yield labs tent, with two 450a LED bulbs, covering 2 x 2 respectively . Carbon filter pulling 188 cfm .And a 4" duct fan, with a " y" .And clamp on can .Wondering if I have sufficient airflow, and if I need to switch to my 6" fan , with a " y", or do my 4 and my 6, with no "y". As y'all can see, I'm spinnin a little! Haha. Any help would be great, and sooo appreciated .Using autopots, which I think I'm really gonna enjoy, just wanna be dialed in .Thanks again

    Personally I would dedicate a fan per duct. That way everything works efficiently and correct.

  6. In a narrower type 2x4 tent I would want to intake passively from on end at the bottom and exhaust with an in-line fan/filter out the top at the other end.

    This would allow the fresh air to come in under the plants and flow across and up.

    A circulation fan above the canopy blowing under the lights to keep it all even is always a good idea.

    Welcome to the farm. Fan per duct is always good but if you have a Y, it’s fine provided you have adequate intake or uptake e air and a separate fan for air movement

  8. It’s a little tent. A single 4” fan set up properly should handle it.

    I am not sure what the Y is for now that I have reread the op.

  13. Yeah, folks, I have two fans available to use, 4 & 6, but only a 4" "input" on bottom, and an "up to 6" on top. And I can use whichever the consensus states!! I'm bowing, to the expertise here!!

    Pull in with the 4 from the bottom, evacuate with the 6 from the top :)
    Or just use it passive and exhaust with the 6 or 4.

    I see you are using leds and your carbon filter is not very big. So using the 4” passively would be better imo.
     
  15. I agree. I can run my open reflector 315 in the 3x3 (almost same square footage as 2x4) with only a 4” inline fan pulling from the top and intake passive through the vents.
