Humidity

I’m having problems humidity in my tent sitting around 70%

Would it be worth adding a bigger inlet fan instead of a dehumidifier because of the dehumidifier producing too much heat in the tent?

I don't know if the bigger inlet fan would help but could you perhaps run a dehumidifier in the room where the tent is or the home somewhere else? I run a dehumidifier in the kitchen which controls the humidity in the whole home.

It all depends on what the humidity in your lung room is.
If your humidity in the lung room is at desired level, 50%works fine for me. Then just make sure the tent is well ventilated. I don't use a inlet fan but have a lot of passive intake.
You will need a dehumidifier if the humidity in the lung room is too high. You need a big enough one so you can control the humidity in the room and not just the tent. Placing it n the tent will raise temps too much.

I run my dehumidifier just outside the tent. Still noticeably warmer when the dehumidifier is blowing in that direction.

If you run slightly higher temps in your tent your RH is going to go down a bit.

A dehu in the tent?

How big is your tent and where is it situated?

Listen to everyone here. Get a big dehumidifier and put it in the room outside of your tent. When my exhaust fan can't handle the humidity anymore I bust out the big boy.

Need to know setup. I only have a 2x2 and its inside with a/c so between clip fan and exhaust fan I do fine keeping it below 70.

Got two of these bad boys. One for backup used in dry room if needed. Room must stay above 65f for any dehuey or the coil freeze. Ya it throws off heat but the less you pack in the tents the less it has to run.

Good to have when its packed wall to wall even if its just a 2x2. It works. I like the robust performance. If the power goes out and using my genny with breaks in between the rh that builds up..

Id want something that will drop room rh in minutes. Frigidaire fanboy here I know I know lol.

I do depend on home ac and outdoor air depending on season to keep cool. I only suffer when its just right temp for ac to stay off and only have warmer air to use from in the home and outside. -10F cooling power vs 20F or more.

Any other time I use -20F + air from outside or ac because its warm enough to stay on all day. Lights off cools room. I perpetuate light cycle in winter in one ten over night to keep warm so dehuey dont freeze.

Such a small room it can get hot or cold easy so during cool seasons Id just keep vent shut and let lights keep a average decent temp in room.

It's hard to say because we know nothing about your setup. Possible solutions are higher temperature, increased air flow, AC, dehumidifier. Both AC and a dehumidifier are often needed.

60% is hight but not unreasonable, I would try and drop it by at least 5%.
What Size of tent do you have? what size of fan? Temp and humidity?
Give us a picture of your setup so we can help you more.

Tent size 1800x3000x2000
Got 2 180mm fans and 1 400mm box fan
Running 3 hsp 400w
150mm inline fan and 200mm exhuast

So my temps and humidity is about the same as yours when I have my fan on speed 2.
I have ACI 150mm fan and a huge carbon filter, tent is 77x150x200cm.
As soon as I change it to speed 3 as the lowest is manage to keep the humidity within 5% of my lung room and the temps within 2c. I have not had this setup for more than a season so don't know how it will behave with seasonal changes.
I also have 4x150mm passive intakes.

Im not sure why yours 200mm fan can't manage it. Do you run it on some controller or is it on full blast?
You could pretty easy check if its more intakes that you need. Just open the door slightly to add more intake and see how it performs.
If humidity goes down then I guess you need more intake.
