Hi, we are growing in a 10x10 grow tent. Humidifier is running most of the time to keep room at about 85%. A central duct is blowing air down from the top of the room 24/7. We didn't realize that the heater in the room that the tent is in, was not working , so the temp in the tent got down into the mid 40's a few nights. We purchased oysters in bags of sterilized straw. Some of the clusters developed orange spots in them. is this an infection? Could it have been caused by excessive humidity? Some of the clusters had water collecting on the caps. Not all of the bags developed this....maybe about 2/3 did.
