I need help w my prop box !! I made this prop box about two weeks ago - it’s sphagnum moss soaked in water and Super Thrive and a small glass of water to help with humidity. First pic is when I made it, second pic is today. There seems to be some mold growing on some of the plants - I’m worried it may be too humid AND I’m worried that the mold will spread. My plan is to take out the glass of water and any visible mold. Any thoughts/advice ??
