Hey all, going to be starting my first indoor grow soon and I've been probably just overthinking it, but does anyone that uses fabric pots set them on anything inside the overflow pan? I was thinking about putting them on a cooling rack that you'd use for cookies and stuff to keep them from sitting in water. Didnt know if anyone has had problems with mold/mildew from sitting directly in pan. Plus I figured it'd give it some more airflow as well. Thoughts?
