Room is approximately 10x10x10
Sealed room ..well maybe a slight leak at bottom of the door, that is fixable if necessary I guess.
Ac unit available
Warm climate most if the year
Approx 33C outside mostly at max

What cfm of fan ?
Use AC ?
sealed room or vented?
DONT WANT TO USE CO2
3 600W LEDS FLOWER

I HAVE TO MAKE SURE NOOOO ODOR OUTSIDE...STEALTHHH

Want to split for veg and flower
4x8 flower 4x4 veg .. Thinking of building two cupboard enclosures in the room. If I do so have an in and out with carbon filter the room itself and have a passive air flow flowing true the cupboards ?

Or partition with the white plastic ? Then how to vent that ?

there are a few options to deal with odor.
first, there are low odor strains that get very good reviews, haven't grown any myself, but people here that have seem to like them.
you can get a carbon filter and an exhaust fan. both come rated in cfm (cubic feet per minute). for a cab you can use a small one of both, just be aware your filter needs to be rated slightly higher than your fan. if you pull air through them too fast they don't work, having a slightly undersized fan keeps you from overpowering your filter.
then they have coronal discharge ozone generators that you install in your exhaust hose. they come on when your fan comes on, and the ozone kills all the odor (except the odor of ozone) before it gets blown outside. they work very well, but they're pretty expensive.
i'd suggest you look into both a filter/fan combo, and low odor strains. if you do both, no one should ever smell anything

OK thanks a lot ...where I am it is hard to get strains ...I already got 4 .. Critucal kush from earthseeds I think, crown royal from crop kings and 2 unknowns. Out of all I favour 1 Critical kush! So I have to go with that .... I'm going to do a 4x8cupboard for flower with 3 600w LEDs. And I guess a 4x4 for veg ... So should I use ... 2 fans for veg cupboard in and out + 2 fans for flower cupboard in and out with carbon + I'm thinking 2 fans for the actual room because it is totally sealed with no windows prob besides a little leakage at entrance door of room ? Think room is approx 10 x 10 x 8

And glad u mentioned not overworking the carbon for better usage ...

I also can put in a ac unit ...but that won't bring in fresh air ...so I HAVE to vent the actual room itself right ? .... Outside temps nearly 33C max all year around ... So if I run the Ac unit do I run fans for the room itself on a timer extracting air ever so often to keep ac temps a bit like every 30mins or so ?

no, you don't have to vent the room, people that run Co2 keep their rooms sealed to keep the co2 in. an ac does nothing for odor, though, you may want to run the fan and filter to get rid of the smell, and you can vent it w/e with the ac running

OK so u think my temps will be OK in there without an ac unit ? .. I think it will still be to hott..tropical climate .no winter ...and u think I will need so many fans cause I will vent don't think I want to do the Co2 thing.. So in and out for the room itself and in and outs for BOTH cupboards ? 6fans?

you shouldn't need an intake for the cupboards, passive intake is usually enough.
are your leds ACTUALLY 600 watts or is that what they're supposed to be equivalent to? 3 600 watt panels might produce a fair amount of heat, 3 200 watt panels would be a lot cooler.
you may not have to worry about heat much if thats the case. i have a 200 watt led panel in my veg tent and it adds zero heat that i can detect.
i was just using Co2 as a reason that people run sealed rooms, just to demonstrate that it can and does work.
if you have an ac, i'd use it, then use the carbon filter on low to keep the smell down. you can vent it right back into your room.
you will need an intake for your room, you do need fresh air coming in, at least leave the door cracked. if you have central heat, see if you can set it so the fan stays on even when its not running, anything to bring fresh air into the room

OK so 4 fans and 1 carbon filter....
One intake and out for the room that will.be running slow with the Ac running to move air slow to keep temps down...
Then 1 out of the flower cupboard with passive in
And 1 out the veg cupboard with passive in
??? Correct ???

sounds like a plan. start with that and see what modifications you need to make. its possible you may need to add intakes for the cabs, but i don't think so.

Well I feel I will get them one time ... Rather prevention than cure ... At least I think I will get an intake for the flower room.
The next thing I have to try and work out is the size of fans and filter to get for each ...ughhh

ok here is the skinny

1 the best way to control the smell is a sealed room
but to have a sealed room work for u .....u need to add Co2 during the lights on
u said u did not want it ....so i will skip that info for u

2 way is called exchange u know about it
A) one the exhaust out needs to have a carbon filter on the front ......this is your main smell stopper (the air getting dumped outside needs to pass over a active carbon filter )
B) if u have a large exhaust ducting 8 10 12 inch u can buy a Ozone gen that fits in the ducting .....this kills everything no smell at all as long as it is running (it will smell like hospital air)......just know this can be a tip off

ok AC ....a ac has a dehumidifier built in .......it will drip water......this water will have cannabis smell in it and dogs can hit on it ......so where u have the ac and it drips in the dirt u should spread coffee grounds into the dirt/area to block the smell......jasmine flowers work too and so do a thick rose bush with thorns and coffee

as for your temps 33c is to high .......u want 21-27c in your grow area .....once it gets above 28c/80f thc degrades faster ....21c/68f the growth rate slows down ( watering/feeding is every 3 days instead of 2)


as for splitting the room u do not need to do that .......buy a tent use that for flowering and use the room for veggie (or build a good enclosure with no light leak for the flower and do the

as for venting it .......u do the tent with the carbon filter and run the line to the window in the grow room do the same thing .....where they meet at the ejection point buy a Wye junction hook the 2 ducting up to and put the other end on ejection point the 2 feed and blow out 1 hole

now doing this is going to make a huge negative pressure in the house/condo/apartment .......is is going to completely change the air flow in the house .....u need to make sure that the air has a path to get into the room ........ideally u want the intake hole to be low to the ground so the coldest air is used to be sucked in and the highest amount of Co2

I have only now seen this ..sorry for late response ..... And thanks a mill for the advice....
Hey can I private msg on this thing ?
Anyway , said I will get 3fans and a carbon filter . one fan in and out of room ..carbon on the out .... The last fan on the out of flowering CUPBOARD 4x8 and the in of it passive as u said. I said id duct the flower straight back into the room and let the carbon deal with it ..... So in the room may stink but hopefully not out side ...
U confused me a bit certain parts of what u wrote but I think I get the drift
