I started to notice a dark green moss like looking stuff on my rockwool. I keep picking it off but it keeps coming back. The temp in my room is 77-84 degrees and about a 47-49% humidity. I have an aero system and the sprayers are running 24/7. The water temp isnt that high its alittle below room temp. I am running a aero system and I havent covered my whole res around so its not 100% dark would this cause moss to grow on my rockwool???
