Any tips for lowering humidity? Need help

Good morning guys, about a week ago I entered flowering and am having quite a few problems with humidity. I have recently moved into a house that essentially has no doors so it's like all one room.. I have a dehumidifier with a tank capacity of 16 liters and it is supposed to cover 30m3 and it has always been effective in rooms where I could seal the room but obviously that is not the case now and even if I put the dehumidifier on 35% at full speed it does practically nothing and the humidity fluctuates between 62/67%. Now ,since I have no money at the moment to be able to invest in a bigger dehumidifier that would cost me even 300/400 euros given the work it has to do, I bought some greenhouse type sheets so that I close a square of the room with the growbox inside so that even if it is not sealed a minimum it can create a mini room where I dehumidify only that square..like the doors before going into the cold rooms. am I screwing up in your opinion? I was reading that someone growing in the basement put the air inlet pipe pointing to the dehumidified air outlet of the dehumidifier but I don't know.... Do you have any advice for me on this? I have more than enough indoor ventilation but I really don't like having all this moisture inside! And yes I have already increased the temperatures but it helps little compared to the fact that minimum I would like to get down to 55%
I thank you in advance

Is the issue that your natural climate has high humidity or that your humidity is rising due to not venting outside?

You can defoliate to reduce transpiration.
I wouldn't go crazy though.

Then make sure you have really good air movement in your grow space to minimise issues caused by higher humidity .

How long until the reservoir on the dehumidifier gets filled?

Can you somehow vent to outside?

It takes about 12 hours to fill up! No I have absolutely no way to let the air out but as I told you I am trying to build a plastic partition to "close off" the room

In the house I had before there were drafts everywhere and the humidity inside was touching 80% but I had a room especially for them and managed it easily , now that it is normally 60/65 here I am having a lot of problems. As I wrote above I'm making a partition to close the part where the growbox is (I'll even attach a picture now) and I'm putting kind of curtains (actually they are sheets to close the greenhouses) attached to the ceiling in such a way as to seal above below and on the sides, I'll make a hole for air extraction that will go through the curtain without opening some side. That's the only thing I've thought about since I would create a microclimate with the humid air extraction outside that square and the dehumidifier inside drying the air inside this square1669815788017..jpg1669815825197..jpg

I ran into a similar problem, im now running 3 dehuies, constant. they pump out when they fill. its a struggle still to keep it humidity in line. my issues are mainly cold windy outside, warm inside the flower area, no floor insulation, and lots of plants in a sealed room. Im afraid i have no advice but more Equipment, its all i could come up with on my grow.

I think you’re on the right track with building a small room to limit the size of the microclimate you’re trying to create. Itl make your dehumidifier more efficient. I’ve actually read about large blocks of salt being used in meat curing chambers to help absorb water and keep humidity at the proper level. Im curious if this would help to buffer a humid environment? A big ass bag of salt is really cheap at a local restaurant supply store. Maybe just stick one in the corner of that mini room/tent and see if it helps any. Bonus, salt never really expires so it’s a lifetime supply ‍♂.

I will try somehow but boy it looks tough...I can't make any changes or holes in the house and the only possible solution would be to leave the window open but too much cold would get in and consider that I sleep in the room next to them...I would die of cold as there are no doors separating the rooms!
I swear I'm thinking them all but boy I don't have the possibility right now to buy a new dehumidifier
I will try to see what effect the mini room I am creating will have but if there is no improvement as far as humidity is concerned I have a hard time finishing the cycle without mold...maybe I covered my ass a little but before the switch I sprayed the girls with micronized sulfur which is also supposed to be a fungicide so hopefully that will do the trick as well

My friend used furring strips to attach panda film to his ceilings with screws, and made a room within a room. Add a zipper, and you have a custom sized tent. A couple of screw or nail holes are super easy to patch and paint too, even if you’re renting. Look at any mold resistant strains too - they tend to be fluffier buds and less prone to rotting. Good luck to ya buddy. I feel ya. I’m in a humid area, and in an unfinished open basement. Luckily, I have a floor drain for the “little dehumidifier that could” who puts in overtime.

Try some plastic and put one of those zippers that stick to the plastic to create a room. This will make it easier to manage a small space as opposed to the whole house humidity issue. Try venting out side or in to an attic space. Just till you have funds to make a more permanent fix.

That is exactly what I am doing! I've already bought some thick plastic sheeting that encloses the whole room, I cut a hole in the plastic and pipe out from there and drain into the kitchen. In between the sheets I put a tear-off closure that holds the sheets together and totally encloses the room bounded by the plastic

Thank you very much brother, I adopted just this method and let's see if it works! I hope so but it's too late now to think about other strains... then consider that it's a temporary arrangement that will last about 9 months so I hope the next house will be much more manageable from a humidity standpoint
