Help to bring down humidity

Hello guys. I'm about to start flowering and I have a problem. RH is 60% with lights on but almost 80% with lights off. Of course I would like to bring it down to 40-50%

 

I am extracting into the same room where my grow tent is (no possibility of extracting outside). RH in the room is always at around 65-70%, so I guess it wouldn't help much to buy a mini dehumidifier and install it in the grow tent, right? What are my options here?

 

Thanks.

I hate to say it mate but I think you are heading for trouble, find somewhere else to grow is probably your best option....

Venting into the same room is your problem, it has to change or you’ll have a high chance of rotten buds come harvest

There’s always a way mate, if your determined to pull a crop off you need somewhere to vent your hot humid air, is it in a bedroom or a basement? Is there no vents you can attach your exhaust ducting to ?

It's in my living room. If I open the window I would freeze the entire flat.

Is there no Wall vents ? Even if you got a dehumidifier you will struggle with growth and bud size and you will be recirculating the same air over and over and in the summer you'll really struggle with temps, as shit as it sounds it’ll be a waste of electric.

 Fuck, I misread the title as saying "Help to bring down humanity".

 

How disappointing.

I live in a flat, no wall vents. I do have a window right behind my growing tent which would be perfect. It is one of these tilting windows that you can only open a bit (enough for the ducting). The problem is the whole flat would get frozen. Is there any way I could avoid this?

 

I want the flowering to be perfect. I have already bought a 25 L dehumidifier.

Put a blind in window, slats closed, or put up closed curtains and then get some black and white sheeting, or preferably white black white as its much thicker and definitely won't let any light out, and sheet over the whole window sealing the edges to the wall with tape

 

Leave the window cracked open and put your ducting through the sheeting. Tape the ducting where it goes through sheeting to seal.

 

From outside it just looks like blinds or a curtain is always shut which is not in the slightest bit uncommon

Wouldn't that allow a lot of cold coming in? Forgive my paint skills:

Put the joint out man lol.

 

Sheet over the whole window. I.e sheet taped to wall around the window. I.e sheet is bigger than window. Once taped aint no air getting in your room. 

You leave the window cracked open. 

You have a blind or curtain up under the sheeting so you cant see that the window is covered in sheeting. 

The exhaust duct runs into a hole in the sheeting. Tape round it too.
