I did actually consider a/c for when it was closed to dehumidify, but I'd prefer a more passive solution.
Do you have any pics of your setup?

Nothing clever to see on my setup, it's just a cheap tin shed that 'leaks' air a lot. The roof used to leak water but I fixed that and gave it an double skin insulating effect with a silverised car Tarpaulin which puts an airgap between the roof and the tarp. I may add some foam insulation next time, the tarp should last about 3-4 years and it is cheap and easy to replace.
I'm lucky in that the Ob sits inside it's own small fenced off area which provides a big degree of side shading and the aspect is southerly which is where all the cool clear breezes come from. The only wall that gets much sun is top half of the north wall and the roof. East, West and South get almost none.
I've heard it suggested that planting bushes on the sunny sides to shade the uninsulated walls will help as well. As you say if you can do it for free all to the good.
Airvents in lower sth walls with gauze filters to keep crawlies out might be a good start.
