Humidity getting high

hanzo385 🙏 ,, atm i'm running 4" intake with 6" out running thru carbon filter with speed control, also its at the end of winter here & have had cold days & nights with some rain thrown in, 👍

When I used to use tents, I always vented it with a 4" fan on low speed. This helped with humidity and temp. This also provided more co2 and pushed out the oxygen. Unless its prone to mildew, 80% isnt bad for them. My veg is usually around 70-80%. Its so irrelevant to me I dont even have a gauge in my veg room. Midway through flower is the only point I really try to keep it below 65% with a dehumidifier.

Good airflow is your best friend but you will need a dehumidifier. Do NOT buy a little cheap one, it won't do any good. You need to spend $150 probably or find a nice used one. Unfortunately they eat a lot of energy too.

Hey Surfer73, Purchasing a dehumidifer would be the easiest and best solution in my opinion, then you'll be able to maintain the rh exaclty where you'd like it. You can try and add an intake fan if you don't already have one, assumming rh is lower outside your tent. You could also try increasing the size of your exhaust fan to push the humidity out. A last option I use if I am stuck is throwing a little space heater in the tent and it will dry things up a little bit. Good luck!
