Filter size for 4x4 tent

Discussion in 'Grow Room Design/Setup' started by booboo111, May 4, 2013.

  1. Want to get a Phresh 550cfm for a 4x4 tent, is that about right, is it overkill ? I was told I could use a 400cfm fan with that, is that a correct match ?

    thx

    Heard alot of good things about the Phresh on here, Just pair the 6" filter and fan. 400cfm would be a good match with 550cfm filter. At full power it would be overkill but add a fan speed controler and you'll be gtg. You coulda just posted this in the other thread kinda the same thing...:)
     
  3. A run a 4" fan for my 4x4 and its more then enough. When I had my 6" in their the side sucked in a shot ton. So I now use 2, 6" inlines in my 4x8 and 4" for my 4x4. Cheaper fan, cheaper scrubber. Win win.
     
  4. He's running 1000w thru a 6"cooltube so idk if the 4" would cut it. Unless he ran a seperate fan for the cooltube cooling. By the time he doe's that might as well spend the extra money on the 6" fan and filter and pick up a speed controller.
     
  5. Yes, I'm spastic !:) My brain is on overload, when I get a new fact, I post, then another and so on...I'm getting ahandle on the nomenclature now.....but I really do appreciate your help !!

  7. I'm running a phresh 550 w/ a 437cfm cyclone fan for scrubbing my 4x4 tent. Works perfect! It's a 1000w hps grow too. Creates a ton of negative pressure...might need to add some extra intake to balance things if the negative pressure worries you.

  8. Simply put bigger the god dam better. Haha. Realistically if your using a 5 inch fan use a 6 inch filter and get a ducting reducer to link it all up. Im currently using a 10inch airforce 2 and have it pulling though a 12 inch rhino pro.. no probs
