Thanks for all the info. Should a mono tub with fresh mushrooms have a smell? There was a very faint smell when I sniffed it at full colonization, hardly noticeable. Today I sniffed my tub and it had an odour that was noticeable. Its not a gross smell or anything. I'm hoping its the smell of mushrooms, but I don't know what they're supposed to smell like. I'm not good at describing smells so I can't really articulate it. The shrooms look healthy though.
Could it be hazardous to smell a contaminated tub?
