I always thought it was appropriate to suck your air through your hoods. Now come to find out they say to "blow" the air. Apparently this is to increase the longevity of your fan.
Thoughts?
Thoughts?
I'm pretty sure you want negative pressure and not positive and pretty much for the reasons you said but opposite. Idk y pulling air through seams and cracks would be an issue when it's just going to be getting pulled through your filter.you get a more powerful vacuum by pulling air through and a weaker one trying to push past obstacles and through...
but...
by pushing you get 'positive' pressure so no smells will bypass your filter because of positive pressure pushing already scrubbed air through any cracks or openings before its intended exhaust point.
If you are pulling air that you want scrubbed there is a chance you will pull unintended air in through seams and cracks that occur after the filter and you will have smells at your exhaust point.
if your not using a filter (I personally suggest to) suck the air through.
^^Dedicate a fan for just your lights.....intake from outside-through lights- back outside. Get a good seal on your ducting.
Not sure. I have 2 in line fans though and running CO2. So I'm guessing suck the air out of the hoods using air from an outside room on one side and back out to another room on the other. Then use my 2nd fan to hook up to the filter. And keep the filtered air in the room and redistribute the CO2. Sound ok?^^
now, @mrgreen2015 'would you rather' add or subtract a variable and minute amount of outside air into your c02 dialled room.
