New room exhaust question

I have just built a new grow room. This room is 9'W by 10'L by 7'H. The main part of the room will be for flowering with my 2 6" raptor hoods housing 1000w HPS bulbs. Also in the room is a sealed cabinet 4'W x 5'L x 5'H for clones and mommies.

I have one exhaust port going outside all done in 6" ducting. Now I need to exhaust both the main room and the sealed room, I have about 40' of 6" ducting, 2 6" Active Air fans, and 1 6" carbon filter.

And suggestions on getting both rooms cleared? and keeping the smell from outdoors?


Thank you

Hmm well first queston is does your (one exhaust port) already have a fan on it or were you going to use one of your two you say you have? Two 6'' inlines wont be enough for 2 lights and a veg chamber. How are you lighting your veg? You should run both raptors together and use one fan to do it unless it gets really hot where you live. I would pull air from outside then thought raptors and out its own port without carbon so I could move air real fast but you got to be good at ducting as it will have to be air tight. Mastic/duct sealant is like dri wall mud and it will dry like a rock and is water/air tight other wise use some 2'' tape foam put it around reflector then slide duct on and use hose clamp to seal it. If the raptors leak any air though seals use some frog tape (fancy masking tape) to seal them up. I dont know how you are lighting the veg so I cant recommend fan. I would use 2 6'' fan for air exchange (one in one out) You should just get some co2 and an ac unit as you are close to a closed system. If you went that rout you can just put the other fan on the scrubber and set it in the middle of the room. Let me know some more details and Ill fix ya up I have built 18 different system over the last 10 years. You name it I've built it. airo dwc rdwc drip ucdwc soiless ucrdwc with drip ebb n flow and nft.

The veg chamber is lit by a 8 bulb t5 unit. I also have a lasko blower fan that I modified the intake with a 6" duct inlet.

I have not installed any fans anywhere yet as of right now.

If your handy with some tools you can open up that t5 and see how many ballast are in it. Mine has 2 one for 4 bulbs and one for 2 bulbs. I put togal switches on them so I can run 4 bulbs,2 bulbs or all 6 which is great if you don't need all of them going and want to cut usage or heat. In my tent with all six running I just have a small inline on top to pull the heat out its not a vortex but a bladed fan. Very low power and very low noise and cheap and it works great. If I were you I would run co2 for all these reasons. 1 much more growth 2 low noise 3 better control of temps 4 no smell getting out 5 shorter grow time leading to quicker turnover 6 higher temps allowed (82f) 7 ac works as dehumidifier 8 less chance of pest 9 much more growth lol. I see as little as 75% more and as much as 200% each harvest. I get 1.8 to 2.2 p per 1 k with co2 and a light rail system with ucdwc and a 63 day turn over in bloom with 14 day clone cycle and 2 week veg.

Right I don't want to debow the thread but I know it's time to setup my room to stay cooler.
I'm taking a vacation and it's going to be unattended. For the most part.
I'm almost 2 weeks into flowering in a hydroponic setup. 8 plants about 4 to 5 feet tall.
I need to go cheap for the immediate solution.
My room is 3.5 ' by 6.5' with 8' ceiling. I have a black rubbermaid with a tray on top.
Humidity is my biggest problem followed by heat, I think we're about to have a heat wave. 3rd issue is smell. I can deal with smell when I get home.
Right now I have a in line fan on my light a four inch. It keeps my room cool enough when our temps are normal. But the humidity is a problem and any high temp outside is a pain.
