You need an inline fan that's connected to the tents ductwork, venting that humidity out then pulling in fresh air from outside.
Lights out temp 15c is good.
Lights on I hope your temps are higher.
If you stay at 90% RH at 15c, your going to be finding bud rot, get that under control right away and confirm the reading of 90% RH is correct by placing your hydrometer outside of the tent or in a jar with a humidity pack that standardizes it to 62%
Best of luck

Oh man.. 90 % RH is not good.. that 15c isn’t terrible. Can you get a dehumidifier? Or can you get a heater in there? Just a space heater in the area will pump the temp up and that in turn will drop that humidity a bit..
definitely gotta figure something out cuz thats way too high

This case I would try to introduce some heat into that tent. Should help dry things out a bit. If you can get it to around 20-23 degrees at night would be ok.
Or you add a dehumidifier. 90 is really high. You wanna be at like 45-55 RH.
Good luck friend 🤙

Low humidity issueTents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.

Ventilation set upI just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?Setup. Ventilation

Won't Oscillate AnymoreI was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.

Air flow methodI removed the hood from the home AC to run cold air directly into the grow tent with a 4 inch duct at the bottom. I have an inline fan to push hot air out to balance out the air pressure at the top.
Is this a good idea or should I just have a fan inside with no in or out?
