Wow, that’s some dedication! I ended up getting a portable AC unit which helps a lot. At a minimum it cuts the humidity a lot. Right now I have it running off an extension cord as faithie999 suggested and I have an electrician coming out next week to trench a new circuit (and a water line) to the detached garage.
Heat is definitely one of the biggest challenges I’m having with the project but I’m hoping that gets a little better as fall approaches.
