How do you cool and dehumidify your tents?

I grow in an uninsulated attic using insulated tents and air ducted from within the house. Stays at a constant 70-75 degrees year round.

Where i live (mountains) i can just set my ac infinity and thats it. Keeps stable rh and temps rarely go above 90. Even when they do once the sun sets everything cools quickly so theyre never too hot for more than a few hours. I think the best thing you can do is find genetics that are adapted to your environment, makes the rest a lot more forgiving.

I lived in Colorado when I was younger. I remember you could soak a bath towel and throw it in a dark corner of the basement and the towel would be dry in an hour.

[2x2] portable ac and dehumidifier during summer ( tent vents to room ac vents out side while cooling down the room dehumidifier in lung room too) during winter i use an oil heater and a humidifier out side of the tent as well. Winter my temps are mid70f to low 80f and summer my temps seem to be slightly cooler at 67-75.

I manage my lung room and let the ac infinity controller dial in the tent

Central air and humidifier. Our RH is SUPER low so I always have a humidifier going in the tent. The only time I use a heater is in the winter, because we keep our place around 68°.

I live in the mid-west. It's 100 out today. High humidity in the summer, low in the winter. I have the AC on in the house and it's nice and cool but does not do a lot to lower the humidity. I decided a month ago that I'm going to stop growing in the summer when the humidity is so high and only grow in the winter when it's low. Even with the AC on it is hard to get the humidity down. I run a 450 watt light so the AC is already working hard enough to deal with that generated heat. Adding the heat from a dehumidifier would only make the temp worse. I have had some problems with mold.
In the winter, the humidity is low, the temp is easy to control and the heat from the lights helps heat the house. I'll run a humidifier if I need to up the humidity.

FYI portable or window AC units dehumidify air as they cool it
i duct a portable AC directly into my tent, and run a duct from the tent to the intake on the AC to create a closed loop
it works really well, but its 1100 Kwh so mighty expensive to run in the summer

I had to use my central air and dehumidifier as well this grow. Definitely switching to fall/winter grows for now on. I had to keep a big oscillating fan circulating inside of my grow room, outside the tent. I close up the tent about halfway, that allows the ac to work and humidifier without overworking both. I also had three fans inside the tent blowing 24/7

Thankfully my condo makes it so easy. My tents are usually 27-28 lights on and 19-21 light off. Just have to use a humidifier during the beginning of sprouting and early veg. No humidifier it stays around 45-50.

Growing in the winter is hard where I live because of how dry it is that time of year, usually just use an ac and dehumidifier until really late in the fall. Once it gets really cold and dry it makes it hard for me to keep the humidity up in the 60s
that shouldnt be an issue at all
im in Canada and winter grows are amazing, for veg you can set your fans really low to keep the RH up, then for flower when you need cool, dry air, turn the fans up
I get my best runs in the winter. Just put a humidifier in. One that takes a filter and just blows cool air out. Not a mist. I’ve had bad luck with the mist kind. Granted I’m not as far up north as you.
