I live in an apartment and my air flow and quality is terrible, I cannot keep white mold from growing on my soil after every watering. I’ve tried cinnamon, I’ve used water mixed with a bit of hydrogen peroxide, and I’ve let water sit out for 24 hrs before watering. I use a moisture meter and let my plants (maranta, pothos, Peperomia, snake) get as dry as is recommended and then wait two-three more days before watering bc of my terrible air. I move them near an open window when I can, but I live in Chicago area and can’t do that in the coming winter months. Any advice, what I can buy or do to help with this problem? Any tips appreciated, I love my plants and want to keep them alive and healthy!!
