I did read it but just because you tried it doesnt mean it shouldnt work. Greenhouse growers dont give up once a outside condition reaches a certain level. They just use better equipment to compete with fighting conditions. Some greenhouse growers run their room through winters with heaters.
With respect to humidity and temperature that you asked, there are two main types of humidity measurements. Absolute humidity and Relative humidity. When temperature increases, the amount of water that can possibly be held increases because the space between molecules increases (lower pressure). When a enviroment with a specific amount of water has a temperature increase of 40°F the amount of water that can be held increases by 500%. But the overall water (absolute humidity) is the same, you only changed the space available for water to occupy. Again relative humidity is not linear like temperature, it is a relative percentage of the amount of water in the air compared to the maximum possible at that specific temperature and pressure.
What i would do personally is run a dehumidifer and ac in the room (i calculated your room at 1200 feet squared with a requirement of around 6 gpd, your dehumidifer seems to be on par with that). and seal your grow tent with a exhaust system (which you already have). When a pressure system with either positive or negative (it doesnt matter if static pressure is ideal) pressure is running, air is being replaced continuously so what happens outside happens inside. Trying to heat or cool or dehumidify inside while this is running is like trying to fly a kite against the wind. Greenhouse growers will deactivate or cycle their ventilation when operating these other systems. Leaving it on would vent any heat/cooling, dehumid or humid air.
Now i know you have already tried this so beer (gulp) with me. You used a dehmudifier, which worked, Great!. But the grow tent humidity stayed high. Well this could be because of either high evaporative sources from the tent such like the water growing system you have, or perhaps your venting system is not working properly or well enough. Or perhaps a combination of both. You also tried the dehumidifer inside, but like i have said, this is pointless as your venting out dry air and bringing in humid air from outside the tent.
So you have a solution that worked, you just have to find a way to get that solution to where you need it. If the ventilation system replaces the air fast enough you should have a humidity similar to outside the tent.
Things to try.
#Turn that ventilation system off and run the dehumidifer inside the tent, sealed.
#Keep the ventilation system running but try improve it with more powerful fans.
#Try turn your circulation fans off, having them on decreases negative pressure as it opposes the force of the fans.
#See if you can find a problem with the ventilation system that could be preventing it from replacing the air fast enough.
