one problem i've run into when making a shed is the flooring. unless you spend a huge amount of time+effort+materials on a foundation, water vapor tends to come up. This causes mold growth and eventually over the span of 5 to 10 years the floor will rot out of under you. (I'm in the Pacific Northwest) Does anyone have recommendations on a cheap moisture tolerant flooring? I am thinking of using Marine-Grade plywood as a subfloor on my current project.
