help on venting and odor

I need to vent 2 600w hps lamps, I am venting directly off of the lamp with ducting connecting to an inline duct or centrifigul fan venting out of the room. My concern is that I am venting out of the room and into an area where people will occassionally be and I know that venting straight out without odor control is going to be a terrible idea. The question is how do I run through a carbon filter or something on my way out.

Ventilation from lighting should be seperate from room ventilation,also your room entilation should be stronger tha the lights ventilation,the room vents then get filtered through carbon filters & the higher pull from room vents will assure that the light vents only pull heat from the lights & not room air.

Air intake(fresh air from outside room ) to lights then vent straight out of room.

Air intake at ground level for room ventilation,this intake can be passive(no fan) as long as the room vents are of enough cfm to have a strong pull,then run a room vent of high enough cfm to exchange 100% of the air in your room within 3 minutes,on the exhaust vent either you can buy a carbon filter or make your own,the exhaust fan should pull air through the filter then push the filtered air from the room.

Dont forget in room air circulation,keep as much volume of air moving around the room as possible,this keeps the fresh air moving & keeps any smells from lingering around any passive air intakes.

so could I intake from ground level through a 4in. inline duct fan (which I already have) air ducted to the light too cool down the bulb (passive intake won't work very well in this room because it is far from air tight so very little air will intake across the lamps). and then use a seperate probably centrifigul fan through the carbon filter out of the room.

My only other question if this will work is won't the air blowing passed the lights just blow more warm air down onto the top of the plant, negating the original pupose of cooling the air?

Thanks alot for your answer though so far, that is a lot of help.

also I notive that you have plans for a diy carbon filter I have read mixed things about how well diy carbon filters actually work. Do you fully stand behing the effects of your diy unit as being somewhat comparable to the quality of store bought units. Thanks again.

Do i fully stand behind the effects of my carbon filter ? Hahaha c'mon man this aint K-mart here & there are no warranty's :mrgreen:,i just showed people what i made for my bud rooms & they are working with great results.

I decided to make my own after buying a legit carbon filter from a hydro shop on ebay,to hell with paying $60 to $100 for $1 worth of carbon,My expensive store bought filter is sitting on a work bench & my home made job's are pulling all the duty for months now, without so much as a whiff.

thanks again panhead, sorry if that sounded like some sort of infomercial soundbite, I was just curious as to how well it worked. Seems to work quite well i guess.

i have two 600 watters too, and the room gets pretty warm and stinky if let go without an exhaust. here are pics of what mine look like. ive attached the duct booster fan directly to the light hoods so there would be no annoying ducting in the way to expand and contract from the light mover.

i dont know if you have a heating problem, but i could only assume if you didnt have an adequate exhaust. but just a side note, the fans work awesome, and theyre cheap (30 each). with the two duct fans, a 10 inch vortex, and a circulating fan, the place is like a tropical windtunnel.

one other quick question to ask here, if I am evacuating the air in the room once a minute how is any sort of co2 set up supposed to work won't i just lose all of that precious co2.

no. co2 will be pointless unless you dedicate 20 minutes to an hour to turn off your fans and let the co2 settle and get absorbed. or you can saturate the air going in and hope it catches onto your plants, but that wouldnt be very cost effective. right now, i have my fan running constantly in the flower room, so all i can really do for co2 is put it to my veg plants which eventually ends up exhausting through the apartment to the flower room.

btw, my room is exhausted at about the same rate, so unless the air is still, co2 wont have a chance because it will always be moving with the cooler air rushing in to get mixed up with the fan then out of the room. you should consider a speed control and slow the fan down to a crawl so the air will still move, but not to the point where it will move so quickly. also, factor in the temperature/humidity. the co2 will be nearly worthless if its too cold, and if too warm the co2 will rise over the incoming cooler air.
