Well my 4*4 tent swings from 50-56% my 4*2 swings from 60-80%. But I just added a mini-dehum to the 4*2 should help the night swings.
Humidifier stays off even when timer starts giving it power.

Does your humidifier have a sensor? If so, then set it ten or fifteen points below the dehuey setting. If not, just turn the thing off. Your plants should be doing the humidifying anyway.

Yes, a 90cfm fan sucks out. And two fans inside tent.
No sensor. I wish, it would definitely simplify all this. I've only had the humidifier for 2 days, I'm going to test some things out. But the second one raised my hum 8% in my 4*4. I'll have to check my night humidity though. Make sure it's not too high.

I grow in my bedroom so climate is a little tricky. But i have been thinking of ways to improve it. Would you recommend a portable ac or humidifier. I have a 50 pint dehum in my bedroom it keeps the humidity from getting to high. Only thing is it gets 82-85 in my tent with 50% RH, that makes everything dry out and the leaves burn on the edges. So I added the mini-humidifiers in my tents, they are small about $30 each. You think I would do better with a real humidifier, or get a portable ac?

You're working way too hard at this.
Increase airflow through your tent.
Reduce nutrient strength.

Is this what's in the tent? What's the total wattage?

4*4 tent lights are ~450W total, 4*2 tent ~ 275W total

I've been where the wild things are. Jungle humid as shit. The foothills coming out of it. People growing lots of plants.
Air movement and a lot of it. Think baby hurricane. The plants can take a lot except for being directly beat on relentlessly. Move the air.

"Insensible loss from the skin cannot be eliminated. Daily loss is about 400 mls in an adult. Insensible loss from the respiratory tract is also about 400 mls/day in an unstressed adult."
Retired RN. I think of this shit because it does matter. You must exchange air. Air movement and air exchange are more important in design than lights to me. Electrical capacity first obviously but as to design it's air.
Failure to do so in a professional legal grow here caused widespread hermies in a strain. Seeds appeared and posts on Facebook. Egos hurt and 3 growers fired which sucked because the head guy of the 3 had bugged since the start of their first winter that humidity was out of control. The fix in Alaska? -48 at night average last winter? 0 for a daytime high? It would be too expensive.
Out the door for them, 300 frigging flowering plants discarded with all the necessary state tracking in METRC . All because of air flow. Not lighting .

You lose almost a liter a day into the atmosphere from skin and breathing alone. Cooking adds more. Showers. Hot water for the dishes.

Only AK has homes that are so tight that RH doesn't have the chance to dissipate.
Colorado gets cold but the RH is so low that excess moisture just isn't a problem.

Exactly and my experience here screams "No!" when guys start talking sealed rooms for CO2. The humidity control alone is a nightmare

Interesting. I've had few such issues.

One really large legal here lost an entire 300 plant crop of one strain that hermied from inability to control humidity. Three buildings, 35,000 square feet under lights but only 1 building with humidity issues. That one

Fuck me. I have the tech that would enable them to kill that kind of RH all winter without either doing air exchange or running a compressor at all.
But as you said above, it was a management failure to listen to their growers.

They had already spent tons of money. These are the same people who had HPS , swapped it out for CMH and then before a single crop came in swapped them back out for HPS. They should have just doubled the CMH if anything. In my opinion.
