Get an inkbird to control the humidifier. What do you have for an exhaust fan?

No!
Here's a problem I have developing with humidity. It's about 7°F outside and condensation is starting to develop on an upstairs window.
I can't wreck the window sills to keep a few plant in the basement. If this has to be the case tell me now, I have to eject.
No exhaust fan right now, trying to keep the humidity in the tent.

I hear that, it's 1 degree and falling here. I popped a hole in an exterior wall and ran my exhaust to a dryer vent. You really want to have air exchange, even if you are dumping it into another room.

I thought your tent was in the basement. Is the little humidifier in your tent really affecting the humidity upstairs? Like have you measured Rh upstairs?
If I open a vent on the top of the tent all the humidity will exchange out in 10 minutes. No fan needed. Then the humidifier will have to be on 100% of the time to keep humidity up in the tent but the humidity will get sucked out onto the upstairs windows. Within a day all my windows will be fogged, window sills wet with clumped paper towel.
And the tent air will still be down to 29% RH.
I think the tent needs to be closed until the plants get larger.

Ok
The air in my house will never get humid because all the moisture will condensate on the cold, subzero metal around door air leaks, window air leaks, dryer vent air leaks. I showed the pic of condensation on the window.
I'll create an envirment for mold in this house if I keep humidity pumping.

You vent outside like I said...I have 2 tents in the basement, both vent outside. No condensation, outside it's 1 and falling, inside its 70.
How much is your heat bills?

I split wood for a few weeks in the summer and fill up an oil tank 1 time for supplemental heat. I either cut trees down myself around March or trade a 1/4 pound for a truck load of logs.
A different paradigm. I was also thinking if other growers have more heat generating equipment that could offset the vent to outside. Or a market. LOL

Hmmm, I was just wondering how much difference there is in the humidity of your entire house when you have the humidifier on vs off. Like it makes a big difference inside the tent, but your entire house is a much larger volume and the water vapor would be much more spread out. A 40% increase in the tent might equal a 1-2% increase up by that window.
Fwiw, some of the windows in my house are old and do that in the winter, but we rarely get into the single digits F where I'm at...

The tent is in an open basement with uninsulated concrete walls and floor. I placed the thermostat outside the tent for 15 minutes. Temp is 62F RH 27%.
Venting to outside means supplemental heat down there. At this point I'd say the tent needs a room built around it.

You need better environmental controls. An ac infinity controller 67 or 69 helps with this. You can set various parameters that will speed up and slow down the air extraction, can control your humidifier, etc etc. This will help keep it in a better zone.
I don't see it that way. The cubic feet in the tent area is (5 x 5 x 6.5) 162. Venting to outside means blowing heat and humidity through the tent out the pipe. Heat and wet will be always on. at the supply port of the tent.
There's no economical way to get the overall basement temp up.

Ok.
I'm in a basement. In a 5x5, running a light at like 80%, and I maintain low 80s once the lights are on....my fan doesn't turn off, it just varies the speed.
Current temp 0 feels like - 9.
My Veg tent runs a little lower as it's a 3x3 with a single Diablo board running at 138 watts. I have a small 2x2 heat mat in that one as well.
