    Default Some help with condensation on my windows

    Hey guys,

    Im late into flower and recently I've noticed my windows are getting condensation on them downstairs and upstairs which is alarming, My tent is a room size tent in the back bedroom, I have 8 plants with a 10" out take with insulated 10m ducting blowing into my upstairs hallway, intake is 4" and from the loft, 2 x 600w lights.

    Should I purchase a dehumidifier and place it in the hallway or would I be better cutting a hole in my ceiling and putting the exhaust ducting into the loft and creating some sort of manifold to blow it out the soffits in the eves?

    Thanks for the help

    Sounds like you would be better off venting out of the house as it sounds like there is a lot of moisture in the extracted air that you really don't want...

    Yeah, I'm using smart pots ( fabric ones) and I've read they allow more moisture to escape from the coco so extra humidity is to be expected.

    Would I be ok venting directly into the loft or should I make sure it goes out the soffits?
    Im thinking of cutting a cardboard box to size as a make shift inlet, i saw a guide online although this was for intake not extraction so I'm not sure if the same principle applies

    I left my bedroom door locked for 2 days whilst I was away. Forgot to crack a window so had the same issue.
    Def worth exhausting outside if poss. It'll make keeping humidity down during flowering easier.

    Any ideas on how to vent outside? Just been into the loft, can't seem to see many exit points although its a new build and the ventilation up there is very good, Maybe I could vent directly into loft and vent into a few cardboard boxes taped together to form a funnel so the air cools down even further before reaching the exit

    Best is to get a dryer vent type terminal or roof top vent . Last and Worst things ya want is to exit a window dead giveaway bud .

    I'm no builder and luckily my cabin is wood so installing a new vent in the wall was simple. Plenty of help on this site tho, I expect you'll get a good answer soon. I've often wondered if extracting to the attic causes humidity issues up there, but having a dehumidifier running would be noisy and costly so maybe it's ok without.

    Thanks man! Much appreciated.

    Apologies for the noob question but would this then be fitted to the actual roof where the tiles etc are? is this something you can DIY or do I need a professional? i do have a friend with a roofing firm to be fair

    Roofing clay tiles ?
    Ive never worked on those . Im from Canada and we dont have that here tbh .

    You can exit the soffit . There are dryer terminals for that also .
    The more profesional it looks . The less likely people will notice . Its whe folk do shitty shoddy work that stands out like a sore thumb is when people notice .

    Do you have an old chimney that is not in use ? Thats what i use in very hot summer minths . In winter fall and spring i vent in my house . Saves me mega on heating bills . I have forced air furnace that circulates the humidty throughout the house and keeps a nice 40-50% rh througbout winter . Makes the skin less crackly

    Go to a quality Mom n Pop hardware store . They will line you up well with a good product

    I work on a lot of new builds, a lot of them already have a tile vent on the roof that goes to the soil stack? Hopefully you have saves you any hassle

    I Spy, at one point, suggested I use a gas exhaust through the tiles... not quite sure what its correct name is though

    Been wondering the same. Thinking ima just cut a hole in bedroom ceiling and extract into the loft. I guess I'll venture up there this weekend and see if there's an easy way to extract out of the loft too. Small loft though :|

    Without actually exiting the roof. Best place in the attic to vent to is right into the apex but outlet facing downwards, moisture will evaporate before it hits the ceiling/insulation below, a tumble drier condensate trap would also work but shouldn't be needed if apex is high enough.

    Chimney stack is ok too as long as not connected to an appliance, not usually applicable to new builds though

    Waste stack is ok as long as open vented and not internal (AAV) air admittance valve, which again new builds tend to have otherwise you will have other issues

    Eaves, not a good idea really and deffo not to remove any bricks to gain better exit
