:0 u had a random mushroom grow in ur soil? sounds like something a bit odd in ur grow room. u got good ventilation and temperature and all that? I had a little weed (non-psychoactive )grow in my pot but a mushroom seems strange.

if the flies come from the soil that is definitely very disgusting. Looks like u are gonnna have to sit around clapping flies with ur hands. KILL THEM!!! or they could just be harmless....
