Ventilation Help please

[Alibaba0101]

Hi all!
I have 2 tents in 1 room ,
2.4x1.2m tent and 1x1m tent
2 floor fans
I leave the windoway in the room open day and night to let cold air in the room

3x 600w hps cool hoods connected to 2 filters (8 inch and 6 inch) and2 fans sucking air outside

(8 inch fan and filter in bigger tent , and 6 inch fan and filter in little tent.)

--My daytime temps run too high up to 90 if I seal it completely
--My night time humidity goes up to 67% , even more if I seal the tent
Daytime humidity is perfect but too high temps if I seal the tent so I have just been leaving the tents wide open in the room to cool them down but I want to seal these tents and use them how they were meant to be used... also I have not been running my fans and filters at night and the two tents exhaust connect at a Y split before being routed out of a 6 inch thru chimmney

Please help guys thanks !!!

Here would be my two cents on it and forgive if I miss understood you. I have 3 ‘tents’ in one room abd fought with the same issue for awhile until I learned about air flow.

Make sure your lights are on a different fan with no filter. I have a 6” through two 600 watts and about 50’ of ducting it’s more then enough. I suck from a basement bedroom and blow into the basement bathroom (makes the bathroom cozy) and it’s basically it’s own sealed unit.
Then just carbon filter out of each tent to the outdoors seperatly. I leave my filter fans on 24/7 but the light fans only come on during lights on.
I see you have a Y adapter. Now I’m sure people use them with success. I have never had a Y work. They are ment to split air to two different ways. Not take air into one pipe. You would need a fan on each side and they back pressure eachother tremendously. Also if one fan fails it’ll dump the heat from one tent into the other.

Last subject is air going out needs to come back in (this is why i isolate my lights to other rooms) my house is to sealed and two 6” fans and a 4” fan negative pressure my house if you can believe it. So you need to calculate how much air your sucking out and make sure that comes back into the room otherwise the fans again back pressure and cause heat build up.

Oh yeah side note. If the chimney is used by anything other then your stuff such as a furnace it will over power your fans. (Tried that to ‍)lol.

Hope that wasn’t to off topic. But I dealt with heat for a solid year and figured alot out

@devilboy13
So what you mean by that is to have 4 exhaust fans (2 for lights and 2 for filters)
And have each fan have its own line of ducting pushing air out ?

The window in that room is open so loads of air coming in .....


Or did you mean to run the filters on inside the room without exhausting from filter

And at same time another fan will be pushing air out?

I will remove the Y split now and run each tent separately to see if that h3lps

Also, i don't have any intake fans I just leave the lower tent vents open I have a 4 inch on its way to get some cold air into the tent

Do you run lights on at night and off during the hottest part of the day?

When using a Y splitter you want a bigger exit, if using an 8" and 6" going in you want like 12" exiting to the chimney or your seriously restricting the airflow.

You want as little ducting as possible and it to be as straight as possible with no slack and few bends.

You want your thermometers out of direct light.

You don't seal tents, you open all lower flaps and vent socks and close all top ones.

@coreywebster
Sorry I meant close the tent not seal it
Thanks for all the advice I will put to use that info

How many fans bro?

 

[devilboy13]

Sorry man. Didn’t realize you replied.

yeah you would have 4 fans. Two for lights two for filters, and it all goes outside. However you can use the light air if you blow through the lights to heat other areas of your home or garage. You just don’t want it back in your room the tents are in. (I live in Canada. That’s precious heat in the winter)

So your tents filter/fan should be sucking the heat/smell out of the tent and blowing it outside. That air being sucked outta your tent needs to be replaced with air. So the tent sucks air from the surrounding room ‘passive intake’ (search this term if you haven’t herd it before). Then that room needs to replace the air which you say you have a window so that should work. Now the temperature of the outside air. And the room the tents are in are all going to play a part in your tents air temperature.
