Should i continue to train this

I was about to say, if you don’t know how to lower it, I had success in smaller rooms with a 500w dehuey, the ones that uses a certain technology I forget, just the more high powered and costing dehueys will bring it down a lot. Best kept outside the tent.

As one said it will lower it even better if you exaust out of the grow room instead of back into. Just a properly spaced dehuey alone would help alot. A decent hygrometer would show what the max and min’s are when you are not looking. It spikes when lights out.

That worked even when it was 90RH outside all season long.

Where do u exhaust?

Out the top of the tent. Then industrial turbo fan mounted in ceiling straight out of the room. I have lower humidity in my room and I pump room air directly into tent. I guess the bag retaining moisture spikes humidity

Are you openly venting into an attic? Or does the ducting continue to the outside?

It just goes straight into attic. There's 2 vents on the roof. Should I invest in a dehumidifier. My humidity is all over the place. If I crank my ac the room goes to 69.and humidity does better in the tent but drops tent temps almost to low

Alwyas keep training until about week 2 or 3 of flower, unless before that point you get your desired shape.

Something like this would work so well, you may need to keep it at 35% just to be able to breathe. Meaning it could do more than what is needed. Cheaper dehueys can work for some people but after seeing how easy mold grows, I don’t mess around.

35 pint is what I have for small bedroom but they make bigger ones for bigger rooms or you can buy more to fill in a large space. Smaller spaces will heat up from the dehuey but if you don’t mind using your AC, you can just crank that up.

I find smaller bedrooms and tents with normal house hold RH 40-60% doesn’t cut it, the tent will get humid quick. Been a while since I had full size garden but this is merely close to my setup. I wouldnt of said anything until you said 70% RH. I know this machine would get it to 45%RH easy.

Just be aware sending the warm humid air into ur attic can create a good environment to culture some mold..
That filter is on ur intake then?

Think of it like this way. If u are pumping air in from a room that is ur “lung room” Control the environment in that room and it’ll be easier to control ur tents environment.

So I would unhook that intake setup and just run passive. Keep the vents mostly closed and ur exhaust on a lower setting. See if it makes a difference. You are making ur AC work twice(or more) as hard with ur current setup and it may be producing more condensation which is counterintuitive.
U may be able to vent in ur lung room if you can control the climate with an AC.

I'm really confused by your intake/exhaust setup...so you have a carbon filter on the intake? And then your exhaust goes straight back into the room, but there is a fan a few feet away drawing air into the attic...?

Yes

I thought you disconnected it in your picture.. the way you have it doesn't make sense then. Put the filter as your intake inside the tent. Run ducting out of the tent from the filter to the fan which vents into your attic.

Open up the bottom rectangular screen windows, or portholes, whatever to let air into the tent.

You shouldn't need to run the fan very hard, and you definitely don't need two fans.

Also, please look into venting to the outside of your home. Can you access your attic there to run more ducting to the outside possibly? You really don't want mold in your attic. That can be a costly fix in the long run.

Never seen anyone use a carbon filter on the intake before. Some people will put a regular air filter of some kind on the intake to catch dust and hair and such. But carbon filters are for blocking odors, I would go with @MtRainDog 's suggestion of just using the vent holes on the tent.

And the fan into the attic is probably sucking mostly air from the room. If you really want to exhaust your tent into the attic, you need to connect those two holes with a duct to direct the air. But I'm not sure that's even necessary.

If it were me, I'd forget the exhaust into the attic, just exhaust back into the room, put the carbon filter on the exhaust side going out of the tent (only if you need it to control smell), and go with a passive intake, no intake fan. Then get a decent sized dehumidifier and put it in the room outside the tent to keep everything dry.

the way you have it setup if you're doing it right, the inside environment will match the outside environment (temp/humidity)
but if battling high humidity with thick buds, i'd recommend

-sealing your building envelope (or the "lung room envelope) and insulating it
-adding air conditioning and a dehumidifier
-adding a heater if really necessary because it is cold and humid
-run 55% humidity or less late flower with plenty of circulation

if you are exhausting air outside, it's bringing air inside. Or not doing anything if it has nowhere to go

I shutdown the attic fan and reduced the exhaust fan power to low. So I'm trying to recirculate room temperature and humidity. Seems to be working for now
