^Try again when your not stoned, i got him. Mould forms if the weed is wet and in a plastic baggie or similar for bout 4 or 5 days. Happened to a mates weed, left it in a baggie when we went to amsterdam. Looks like white fuzz, like on a peach except whiter. He dried and smoked it, potency was poor to say the least and smelt off, but it did look a better after he dried it. Still look shitty but hey
