As the title says, we have mold growing across all surfaces in the basement currently. Long story short, we live in Tennessee and it's been so hot and humid, we have been running the AC nonstop. There's no insulation below the floor, and so the unfinished basement gets nice and cool, causing moisture to condense rapidly under there and has caused mold to appear on the wood surfaces. 

Looking for a short term solution to keep this from getting worse, and a long term solution to keep it away. 1,400 square foot home built in 2022, first owners. Lowest point is a foot tall, highest is 14 feet, for air volume reference. 

Neighbors told me to shut the basement vents to the outside, but we live on a hill and there is so much moisture seeping through the soil underneath and straight through the cinder block foundation, it would get in anyway and then become fully stagnant air. 

Do I shut all but two vents, and plumb a dehumidifier straight through one, to let it vent positive pressure out the other side?

Am I fighting a losing battle with the foundation how it is? Don't have money to pay for encapsulation, and not sure if it would be a good idea anyway, as it would just trap moisture under the barrier. There is a heavy tarp covering the dirt up to the edges, but it's obviously not meant for this. I've repeatedly fought off mice (nested in and ate the HVAC) and hordes of bugs, so almost all gaps are gone. 

I've attached photos. Please help. Need a DIY solution if at all possible due to minimal funds. No idea which flair to stick this under.
