With such a wet environment, using a fan not designed for it may present a significant electrical hazard. Are you able to provide a ground fault protection outlet to supply the tent appliances?

Indoor grow tent! Swedish snus variety Tofta!

I can use anything that it is a plug in device so I guess so but first option is to remove the conditions for condensation.
I like to have both belt and braces so I may pick one up and plug it in.
When the fog from the humidifier evaporates it takes heat from the environment so the conditions for condensation only happen when the mist is being pulled through the fan and the endothermic reaction cools down the fan cage to point of condensation.
This is not typical and I think I have found a solution for the problem, I am moving the humidifier and changing direction of the fog to start with.
Electricity safety is allways a concern, before I hanged the fan upside down it was not safe but now it is.
The most important safety step is to not have any electrical wires or tools at the bottom of the tent, those should allways be raised from the ground.
In other words, the problem was that the humidifier and the fan was too close to eachother, if I manage to spread the endothermic reaction out over a larger area the problem will literally evaporate.

I had to lower the humidifier to normal/medium setting.
I have limited options with my $30 humidifier with just three different settings but I accept the challenge.
I must use medium/normal setting.
DIY solutions are fun to operate and I don't say no to a good deal.
Here is a fun comparison!
Outdoor:
Weather: Overcast 0°C (32°F)
Humidity: 80%
Light intensity: 5000 Lux at noon
Plant: Snowdrop
Indoor:
Temperature at flower height: 28°C (82.4°F)
Humidity at flower height: 60.5%
Light intensity at flower height: 180'000 Lux
Plant: Tobacco
Conclusion:
Indoor growing is more fun during winter but the Snowdrop is a cool little plant!
Tobacco flowers can tolerate very high intensity light produced by Samsung lm301b diodes.

Just curious but what is the ambient temp inside the home but outside the tent?
What are those white flowers? They are very hardy for cold weather and snow.

I have it warm in my apartment, still got the heaters going but winter is allmost over now.
It is 22-23°C (about 73°F).
It is about five degrees celsius warmer in the tent than in the room.
I think it is good.
I subtract about five degrees from the temperature at flower height to compare the temperature to HPS grow lights that emit much more infrared radiation (heat).
Also the sun emit a lot of infrared radiation, the LED light do not heat the skin nearly as much as the sun does a sunny day so to adjust for the lack of infrared heat I like to have a higher temperature in the grow tent.
You can read more about the comparison between LED and HPS lights and leaf temperature here:

It is called snowdrop.
Galanthus nivalis - Wikipedia
I find it fascinating how the seeds germinate at exactly the same time, it is almost like if they communicate with eachother.
Cool little plant growing in my neighborhood.
Here are all the temperature measurements I need. Room temperature, flower height & extracted air when light at max intensity and all fans running.
Room temperature: 22.3°C (72°F)
Flower height temperature: 28.3°C (83°F)
Air extraction temperature: 27.0°C (80.6°F)
Flower height temperature is room temperature +5°C or +11°F if lights are on max and all fans are running. It is as expected.
With a variable speed controller on the extraction fan I could change the difference between room temperature and grow tent temperature but not by much and then I would also want to adjust the humidifier accordingly, preferable with an integrated hygrostat.
Such a setup is very neat, especially if one need darkness in the tent because then the humidifier will automatically adjust to the lower temperature at night.
There is allways the possibility to upgrade later and I think it is a good challenge for the blog to get away with stuff from the hardware store.
I call this a success, there are room for improvement but everything works and I can lower the temperature in the tent by switching off the heaters in the apartment.
I doubt my apartment will be much warmer during summer but it depends where one lives.
For the summer one may need more ventilation or to take a summer break from indoor growing.
The humidifier cost $30 and the extraction fan cost $20, both from the same hardware store.
Compare that to a fan with variable speed $120 and humidifier with integrated hygrostat $60.
Sorry the blog is a mess and I repeat some things. I am a novice and improving my blog skills that is why.

Look how close to the light the flower grow!
The flower is less than two inches below the light. The light meter max out at 250'000 Lux.
One flower is deformed, must be the light intensity, not good.
I tucked it to the side. Flowers don't need a lot of light.

Now the flowers are tied to the wall by a red rope.
The deformed flower was actually a twin with one normal and one deformed flower. It is not a big deal, it is just some light burn, things like that happen in an indoor grow. The freak is removed.
Everything is nice and tidy again. Trial & Error.

Sorry to hear about your father. I miss mine. We had our differences in my younger years, but reconciled as we both got older and maybe wiser.It is a nice introduction to DIY-crosses for us casual pollen chuckers.
I am so happy that fair trade tobacco took me in and let me do a grow blog here.
I will try my best to return the favour.
I will soon get my fathers savings, he passed away in covid-19. I miss him so much and want to spend the money on my hobbies that is growing, being outdoors and taking photographs.
It is such a pleasure to grow legal tobacco, it was always a pain to not be allowed to talk about my hobbies, I just love to grow stuff and to grow tobacco is so much more fun than to grow illegal plants..
I know we are not allowed to talk about illegal plants but I consider it is obvious where my indoor grow skills come from, we all have our backpacks and mine is that I like to grow medicinal plants.
I consider tobacco a medicinal plant that is more fun to grow cause I like beautiful flowers and tobacco has so beautiful flowers. My other passion is to grow flowers, violets is my favourite.
That is known as fasciation (in plants), and is often caused by environmental stressors. In certain genetic variants, fasciation may be more common.

Very good that you reconciled my friend!
They are still with us I think.
It was a relief when the doctors decided to switch off the machines, my father died the ventilator death because of covid-19.
My father was a fly fisherman, I am so thankful for all the fishing trips he brought me on.
It is thanks to him that I feel home in the forest.
This is my father when he was young, the salmon is 11.2 kg (24.7 lbs) and caught by fly fishing in a norwegian stream. He became 71 years old.
Fasciation exactly!
Glad to know a new word.
It is also called light stress, too much light.
Different species react in different ways.
250'000 Lux is two times the sun light so it means that tobacco flowers can take a lot of light but not too much.
I consider 250'000 lux above the maximum level the tobacco plant can tolerate, I will tuck away the flowers in the future.
This is how I learn, Trial & Error and Ad-hoc.
The next grow I know better where the limits are.
I never panic about anything in the grow, I just learn new things for the next grow.
This is just how I operate, by curiosity and trial & error.
I am glad to share my mistakes in a grow blog here.
Together we will learn more than one alone.

The post linked below shows a fasciated leaf on an Oriental (resembling Izmir Ozbas) unknown variety from ARS-GRIN. [i.e. ARS-GRIN had not been able to identify it. Their curator sent me the seed for a grow-out and detailed description.] The blossoms of this plant also developed fasciation.
