I believe his fan is pulling air already. He's refferring to his can filter at the beginning of the string there, I think. I think I'm going to switch to what you've got going by taking my filter out of the run that the lights are on too. Seems to make more sense to me than what I've got now. Besides, I could then control the speed at which the air is drawn through the filter without affecting the cooling of my lights. IT's actually how I installed everything at first but then I got the new filter and didn't have a decent fan for it so I just stuck it before the first light to stop filling the garage with sweet funk.
It's working good so far but I'm only using one of the lights right now with only a few plants. I don't think it's going to work very well once I fill the whole space with flowering ladies. Guess I'll be needing another fan
hey dez your are correct. i read his psot a bit wrong, my bad.
also i want to make an edit, forgtot to put in a whole part of a sentence:
what up bro? one fact and one opinion. fact: those fans(inline, exhaust) are desinged to pull air. dont get me wrong, they do work , for the most part, if you have the air pushing through. but they work much, much better and are more efficient when pulling. opinion: i have mine as such < FAN(on top outside of tent) < DUCTING <LIGHT <DUCTING <LIGHT <DUCTING hanging out of the other side of the tent,
then i have it going into one of the other top duct holes sucking out moisture and heat from the ceiling of the tent, with an open vent at the bottom of the tent sucking in cool air from the floor. i think you might do a little better if you just take your ducting loose and turn your fan around. hope that helps bro.
kinda makes a difference in my description i guess, also if it gets a little warm i have my window a/c unit configured,and ducted to one of the side duct holes to blow in the cold air.
now as far as the filter issue, i dont need them. the NL doesnt really have a loud smell at all, thats why i chose it. didnt want to have to hassle with carbon filters when i started(may be reconsidering though). but maybe its the filter. cause where ever, or however your gonna have that filter positioned its going to be having air from inside the tent going through it, as it is now. so, i dont know maybe its the filter, maybe the "filter" needs to be turned around, maybe some one else near by has an op going.LOL. but that just my opinion on the filter, because i really have no experience with them. sorry. sorry Don G.
PEACE!!!
