Need help with venting asap!!!!!

HIGH TO ONE AND ALL - i NEED SOME HELP SETTING UP THE VENTING SYSTEM FOR MY CLOSET ITS 66"L x 26"w x93"h - Ive got the idea but need advice making my mind up as to how to go about this. Heres what Im thinking- Ive got a 6" dryer vent i will be removing the louvers off for fresh intake and driling a hole thru the closet wall to the outside of the house- I got a 6" inline blower/booster and a cpl 6" elbows and ducting. I will connect a 90 degree elbow to the dryer vent- then a Tee -type wye duct fitting to let fresh air out of the opening to the canopy while the top will go up and across my 6" air cooled 600w - than exhaust the air up thru to the attic via a vortex type fan where itll then be connected to a carbon filter. Should i put the fan in the attic or the ceiling of the closet? Does this sound ok - or should I use 8" duct and branch off to 6" as it says here: https://www.rollitup.org/subcools-old-school-organics/50791-venting-grow-room-efficiency-get.html
For added space Im also thinking of maybe just running it all thru the attic and dropping down my intake thru the ceiling thru a 2way connector (one duct for the hood one for the canopy)??????
Please any and all advice would be helpful - Im trying to set this up ASAP as ive got some huge babies I need to get into flower

sounds like a good plan to me. Should work fine

thanks for the quick reply lol which plan is that? I have a cpl different scenarios there- Do you think I should keep it all in the closet or do it thru the attic- I just read somewhere that venting into the attic in cold places causes moisture- what do you think>?

I meant Subcools thread on venting that you linked. That was a very nice demonstration.
A picture says a 1000 words, I know you are in a rush and may not have time to post pics, but it may help.
If it were me, I would hook up your vent like this...
First, connect your carbon air scrubber to a 6" duct
From the air filter, connect the 6" duct to your air cooled light
from the light go to the inline fan, and finally from the inline fan have it blowing directly outside of the house. Not into the attic.
The grow room is in your closet right? Well as long as your fan is pulling air out of your air cooled light, and pushing it outside of your house, it will create a passive air intake system. So fresh air from your bedroom will be flowing into the closet, and the hot air from the light will go outside the house.
I hope that makes sense

Thanks that seems much less complicated - So let me get this straight - i connect the scrubber IN the closet by the ceiling to a 6" duct- (then when you say from the air filter connect a 6" duct do you mean the scrubber as "air filter"?) then you say I run the duct thru the light - gos out the other side thru an inline fan and then outside? You said I will be pulling fresh air from the room- but itll be an enclosed closet - do you mean pull fresh air from the 6" dryer vent that leads outside? Should i just cut a hole in the wall outside n place the dryer vent there for my fresh air?

By air filter I mean scrubber. Yes.
Yeah thats pretty much what I was thinking. Also, the fresh air should come into the closet from inside the house. That way you know the air coming in is the tempature you want it to be. Not the tempature of outside air that is always changing and uncontrollable.
If it is a completely sealed closet, then I would recomend cutting a 6" hole into a nearby room. I dont know what your set up looks like so Im not sure if its possible to do this discretely. It is very important to conceal any evidence of a grow.

Are you growing in the laundry room? Did you take out the washer and dryer and then turn it into a grow room?
Sounds like a good space to me, and the original dryer vent would be perfect as a vent going outside.

no unfortunately the only space available is in my closets- its in the main bedroom of my house - i have two closets that are the same size side by side seperated by less than a ft of wall- (the size posted above is for each NOT for both) i have moved the veg closet to the left closet and dont really plan to vent it as the windows are open most of the time and there are only flourescents in there --I moved the veg over to the left so i can vent the flowering closet right outside plus I think if I make the left closet the flowering chamber - ppl will be able to hear the fan as that left closet is right on the other side of the houses main hallway-could i get away with this http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100396544 (note i have the way weaker 6" in my posession- but dont think itld be enough) or do you recommend a REAL inline can fan like this http://cheaphydroponics.com/store/imported-products/can-fan-6-inline-fan-ho-440cfm/prod_170.html - what cfm and brand would you recommend for stealth? Also you suggested i should just set up the intake as a hole in the closet door - how can i make this light proof? thanks for all ur hlp so far man - i gotta go all this unsureness is making me stress out !!

Just a suggestion. If you have access to your attic, run all of your venting equipment up there. Out of sight, doesn't take up valuable space, and is much quieter. Just run the exhaust of the inline fan out some kind of a vent up there.

www.tjernlund.com/Retail/fans.htm It's actually 530 cfm. The model # M-6. The fan moves a ton of air. I have used the valuline and cap fans in the past. This fan is much better in my opinion. You can Email them with a competitors web sight and fan , like the valuline, and they will match the price. I got mine for $90 shipped. I use it to exhaust air from two small rooms, and I have a 465 cfm pulling threw two reflectors.
Heres a couple pics that might be helpful.

thanks man good looking out ---will I need two fans like you or can i get away with just one m-6 530 cfm? I am confused since thebigtomato told me to put my filter first -then duct down to the light - duct out the light to fan to the outside. Wouldnt it make more sense to add the filter to the end of the exhaust as opposed to the intake so the air being exhausted from both closets can be filtered thru it n not stink up the house?

Generally if your only pulling air from one room, you would start at the scrubber. If your pulling air from both rooms, You would probably want to use one fan dedicated to scrubbing and venting, and another to remove the source heat from the reflector. This way, you pretty much have total control over the growing enviroment.

ok i think i almost got it u say ill need 2 fans if im pulling air from both rooms buuuuuut I was just thinking of attaching a y fitting to the beginning of the fan and just running flex down to exhaust my veg room as well (since there are no hot lights in here just flouros) would this work? its not completely nescessary as the veg doesnt smell too bad and gets plenty of fresh air from the windows being open half the time. so with or w/o this y fitting and extra flex for the veg exhaust(which im waiting on your approval) this is the setup I got so far----scrubber in attic-duct down to closet-elbow-light-elbow- duct up to attic -90 degree elbow -fan -duct-outside- i almost feel like i can exhale.........BUT WAIT...how do i bring in the fresh air to the bottom of the canopy- cut a hole in my closet door? if so then how do i make this light proof? I cant even explain how appreciative I am for your 2c - thank you guys for all ur hlp so far ---- im almost there!

++++ Also dont you guys think it would be better for smell purposes to put the scrubber in the closet right at the ceiling?

The two fans probably wouldn't be necessary, just more efficient. If I were you I would start with the one inline fan and see how it works out. If it doesn't, you can always add a second.

Yes you will need some kind of passive intake. being a hole in the bottom of your closet, or a hole going into another cool room in the house. Either way, you can build a small three sided box to place over the hole, keeping the open side of the box right down close to the floor. Cover the bottom with a black nylon, and it should keep your space light proof. Hope that makes sense.

Would probably work eather way. I dont use one so I cant say for sure.

Carbon air filters do not remove the smell of flowering marijuana plants completely. They do a good job of reducing the smell, but dont eliminate it completely. That is why I dont like to vent into the attic. The attic will smell and sometimes that can lead to the entire house smelling of pot. I would vent it outside if possible, but thats just how I see it.
If you cut a hole in your closet door, you can run 6" duct from that hole to the other side of your closet. That way light will not penetrate the hole you cut. Then for the other side of the door put an a/c register, or grill over the hole you cut. So that way it looks like a vent for the closet. Does that makes sense?

it was all making sense till i talked to an old timer today who makes his own housing for ballasts - his own hoods & nutes and has his his own full spectrum bulb with ge- he suggested i get rid of the air cooled sun 2 hood he called an atrocity and 600w and either get 2 400s or cuz i have taller plants just drop a 1000 watt hps with one of his non-air cooled hoods he says are more efficient - exhaust would thru an 8" max fan and use a lazer ozone ionizer(so dont have to replace filter every yr) in a box in the attic and run it thru 20 ft of duct to the outside for the smell. Do you think this is enough to keep the heat down - I am very skeptable of putting that 1000 watter in that tight space but he says I should probably be ok even with a 6" 500 cfm fan but suggests i upgrade to the 8" max can? What do you guys think I'm tripping now and more confused as to what to do even more so than before I went in. He gave me another article to read published by hortilux where they tested all the digital ballasts and no light made hps or mh is made for digital except the pulse start mh full spectrums - Now I want to return my digital 600w and 6" fan - what should i do? heres a pic of his hood he claims is way superior to any box type hood

I wouldnt say your air cooled sun 2 hood is an atrocity. It may not be the best available light in the world, but man if you want to grow some tasty buds, it will do the trick. There are plenty of journals with great results from cfls, 250hps and 400hps.
If it were me, I would stick with what you have. I have a 400 watt hps and I couldnt be happier. There are alot of grow journals on this forum and people are growing some amazing weed with 400 watters.
Stick with your original plan, use the 600 hps and 400 hps and then after 3 or 4 months show that guy your results. Are you planning on doing a journal?

Here is a thread for 400 watt hps! Take a look!
https://www.rollitup.org/grow-room-design-setup/61539-400w-club-show-off-your.html

I have the 600 watt hps sun supply light and I love it!!
I have amazing results from 4 plants at a time. You could do more, but its for my personal use only.
I dont think you will be upset with what you have.
peace
