plexiglass makes it easier to see where the sterile air ends. 

i love those filters.  i use an 8" hydrofarm fan but i'd get a 10" one and a speed controller if you can.  I'd use a 12" plenum.

That looks interesting and it is within my budget! Just to confirm - are you are talking about the 760cfm model? I'm curious how you secured it to your hood - did you just secure it directly into the wood, or did you buy ducts/mounting accessories?




yeah i just screwed it to the box and siliconed the crap out of it.  it comes with a mounting bracket...

I would still like to confirm if the math is correct to determine the resistance at a lower flow rate. It could potentially help save on materials. If the 8" works for you, why would you use the 10" one? Have you tested your end result CFM?




i'm not using it in a laminar flow hood, just on the intake of my grow room.  it's always better to have overkill.  only about $30 difference.
