all day and all night tents are at 80 to 90 %

i cant seem to get them down

vent directly from home hvac , furnace has been running (so house should be dry)

all fans (vent and intake ) running on temp switches

all tents vent into lung room , but intakes are directly off of hvac ( not lung room)

i do not have a humidity issue in my home

so WHY ?

how is you system setup? Is your extractor fan outside or inside?

If outside air the tent is 65 and inside it 90 then its not drawing the air out of the tent. Something is blocked, either the intake or if the fan is outsiders then the fan isnt connected properly somewhere. Make sure all the ties are tight on ducting and theres enough intakes open at the bottom and top is tight. Can temporarily disconnect your carbon filter as well see if there a big improvement

my carbon af is on intake side all exhaust is working fine

[smokythebear]

in all 5 tents at the same time and different sensors… i find that odd

0

[Nugwhisperer]

Yeah that is veryy odd! I’d only get 90% if I forgot to turn on the extractor

0

[smokythebear]

yea mine (intake and exhaust are on a temp switch that comes on at 77 deg and off at 72 deg

both at same time to reduce internal pressures in the tent

0

[Nugwhisperer]

What’s it like with them running continuously? Or are the currently running practically continually for heat?

0

[smokythebear]

haven’t tried yet , when i open the tents and let them air out , they dry up like the fucking desert

0

[Nugwhisperer]

Yeah I get the feeling it’s just in a temp range that it doesn’t switch on enough? Disable the temp control and leave it running got to be the next step 😄

[Nugwhisperer]

I just leave mine on setting 2 for light cycle and 1 for night as I like quiet lol continuously run, you find what setting it need to be to keep it in a good range temps and humidity wise.

0

[Nugwhisperer]

Can you change your ‘on/off’ setting to be for humidity and see where it goes? or just run it continuously and see if that helps?!

0

[smokythebear]

ive got two more exhaust fans and the inkbird humidity controller . im going to install on my bedroom tent and see if that helps

if not ill be bitchn again lol

0

[smokythebear]

no unfortunately

Try to run the exhaust constantly like @calikush describes.

If everything works fine, but your only extracting air at a specific temp, that could accumulated humidity imo. 🤷‍♂️

[oilfarmerinhiding]

check that the plants haven’t grown up into the prob itself. its happened to me, if it touching a leaf is will be 90+% humidity. ran around like a chicken with my head cut off until i found it

0

[smokythebear]

did, thats the first thing i checked lol

[Newleaf]

Are you pulling air into the tent from somehwere else in the house? Or is it from the room your tent is in?

0

[smokythebear]

straight out of my home hvac

actually have booster fans on intake while being hooked up to my controlled hvac

temp and humidity is very good on my home unit

inside of tent walls are wet and i dont like that

[Newleaf]

Sorry was busy all day yesterday. Ok so what temp is your hvac at? You have to remember Relative Humidty is dependent on temperature. Im going to throw an example out here. It may not be mathematically correct but it should help you understand your problem. Ok, so say you have a room that is 80° at 60%rh. Now say you have a wine fridge that is 40° at 60%rh. That wine fridge is in the 80° room. Everytime you open your door to that fridge and the 80° air gets sucked into the wine fridge. The fridge may spike to 90-100%rh inside the fridge. To the point you start to see condensation on the items in the fridge. So what im trying to say is 60%rh at 80° is technically holding more moisture than the 60%rh at 40°. Now when you introduce that 80° air to the 40° air. The 40° air cant hold as much mositure as the 80° air. So instead of it being 60% rh when you mix the two together it spikes to 90-100% inside the fridge.

that makes sense in a refrigerated area

but my tents are warmer than the air going in

so.its the exact opposite of your theory…

my rh outside my tent is between 50 and 60 at 62 deg

my tents are 80 to 90 rh at 80 deg

I believe you stated your own problem. you vent into your lung room. I also grow in my basement vent all 3 tents to outside also vent lung room to outside. I replace my air from a intake from outside. if you are exhausting your high humidity into your lung room it will be sucked in your tent screens every time your exhaust fans come on.

0

[smokythebear]

i dont have tent screens that are open all

intake is controlled through my hvac . none comes from my lung room

0

[Nugwhisperer]

Can you take some pictures of one of your setups, of how air get into your tent and how it exits? The full ‘system’ Picture speaks a thousand words and all lol

0

[smokythebear]

no my intake vent to far away

basically attached to my duct work (hvac) down to bottom of tent via tube

and my exhaust straight out of the tent

0

[Thickems]

Do you have a fan on this intake? Or does the hvac control the airflow? How strong of exhaust is pulling the intake air? Hvac systems are not made for extra air currents. If you are pulling air through your hvac without it active running you can be drawing in extra moisture. Im a licensed plumber that works with hvac and water supply to them as a career. Im pretty confident you are drawing unwanted air through your hvac when it is not running.

[smokythebear]

ive checked my duct inside when running and not both times rh is under 60

ive worked in the field as well and that was the first thing i thought of .

but even if just the fan or the heat or the ac on or off the rh stays the same in my home

even on all floors , basement used to be higher but only in spring time , ive owned my home for 40 years

0

[smokythebear]

im sorry , yes. inlet fans on all tents separately on temp switches

0

[Thickems]

If 1 duct is drawing through your external vent because a fan, the rest of the duct wont be affected. Why only your tent is getting humid, its drawing to there and not the rest of your house. Its all in your airflow in and out your tent. Just because it didnt do it before doesnt mean a clog didnt happen in an exhaust or anything. This is your air through the hvac causing your issue. Take it off the hvac and draw from a neighbor room i bet it changes.

Pull your intake for a day, see if it changes. If it goes down you know its your hvac. This could be from a cold air return gathering moisture, to your tent exhaust fan pulling when your furnace is off. I hooked my tent to a furnace duct and didnt get it correct. Burnt the furnace up because the exhaust pulling air through it. Hooking other fans and duct and climate into a controlled hvac is not a good idea.

0

[smokythebear]

im not sure how that burnt the furnace up? but i tried that and it made no difference , my upstairs tent is not hooked to my hvac and its having the same issue , rh at intake fan is 55 inside 92rh

0

[Thickems]

Drawing extra air. Ruined equilibrium temp. I was cooling my sensors more than the furnace could heat. It over worked it. If its hooked to hvac im going with that being issue. If its multiple tents through out the house, you are to wet and not exhausting enough. If your home is in 60% and all tents are hitting 90% then you are getting extra moisture in the intake. Or your sensors are faulty, its technology and has faults no matter how good it is.

Sounds like a condensation issue..

[Newleaf]

I would still try and pull air from your hvac into your basement (lung room) just dont shoot it strait into the tent. From what you’ve said i think thats what your doing. Use the hvac to warm up the lung room, then pull that air from the lung room into your tent. I bet your getting more of a spike when the lights are off in your tent, and then the tent is probably colder than your hvac system.

0

[smokythebear]

my tents are warmer than my house, and my tents vent into my basement

my basement and house are at 56 rh and my tents are at 85 to 90 rh

0

[Newleaf]

Id still try pulling air from the lung room instead of the hvac. It might be slightly colder then in your tent, but i bet it will solve your humidty issue. Give it shot. See what happens.

0

[smokythebear]

i did that for a week and no change

[Newleaf]

This is honestly a mystery. I wish we could help, but this seems like one of those problems we’d have to be on site. Have you tried using a different type of hygrometer other than the inkbirds? Just to conpare to?

0

[dales_dankness]

I don’t know if this helps, but I have a set up kind of like this were I have 3 tents in a bedroom in the basement and I ended up cutting a hole in the wall to vent the lung room out into the basement. It is a 6in inline fan that runs on high all the time with a carbon flitter on it. That way I always have fresh air that is stable rh coming into my room at all times. then I run all my fans at a lower setting all the time then ramp up as needed with the ac infinity controller. keeps my rh in check but I know not everyone wants to cut a hole in the wall

0

[smokythebear]

my basment is all open (full of shit of coures 40 yrs) but open fans always moving air for circulation always in low rh , ive been doing this along time and im stumoped , first time this has happened

nothing , and i mean nothing has changed in 3yrs except the temp out side , which has no concern in my controlled environment, at least in the last 3 years, same vent system , same tents, same RH value, same lights , same EVERYTHING, im sooooooooooo fucking frustrated

so far no mold in buds , but its a comn and im going to be sooooo pissed at myself

0

[dales_dankness]

That’s super frustrating I glad you found the problem and it is starting to dry out for you

0

[Unknown Member]

From what I understand you stop extracting air if your temp is below 72 degrees. In my setup during the night the temps can get below that and my humidity would rise.

Have you tried to run your extracting fan 24/7 instead of temp regulated?

Sorry if this is stupid…

[smokythebear]

no input is stupid !!!!!

havent yet but that is todays experiment when i get home
