hey all, my new LP is doing great (eats like a marathon runner) but i underestimated Florida humidity. i havnt misted his tank even once since i got him, but its still 80% humidity and hes starting to get some white mold growth on the substrate. i scooped out as much mold as i could, and poked twice as much ventilation into the container. should that be good, or do i need to change ALL the substrate?
