Sorry to hear that, I cant even imagine trying with those conditions. We get high humidity in the mornings, 78% right now, temp 57 deg. , but by afternoon its in the 30%'s and 75 to 90 deg. on average. Normally no rain between June and mid September, if so its a small amount then dry again. My problems come from late September to harvest in mid October, more rain, foggy mornings that sometimes don't clear all day.
I think you need a totally enclosed greenhouse with a big dehumidifier?, I know, what a pain.
