Certain types of plywood are a magnet for mold growth. The natural oils in the wood (like birch) plus certain types of glues that contain organic compounds are the perfect environment for mold to thrive. From my understanding, marine-grade plywoods are more resistant to mold growth, and of course, you could paint the plywood with mold-inhibiting paint. This is a supply chain issue that needs addressed at the source (supplier level). There are well known charts that define safe operating environments for temperature and humidity. If you go outside these bounds, its easy to calculate the number of days until an object develops mold. https://energyhandyman.com/knowledge-library/mold-chart-for-temperature-and-humidity-monitors/ https://energyhandyman.com/knowledge-library/mold-chart-for-...
