Below are two photos of my fruit hardwood cuttings in their enclosure, one with the "hood" on and the other with the hood off.
Each day when the room temperature is close to the soil temperature, I remove the hood and check on the cuttings. Today I found an outbreak of white fluffy mold growing on one node of one of the fig cuttings. I wiped it off with a tissue and then sprayed it and the surrounding cuttings lightly with a fungicide. I also removed excess moisture from the inside of the hood to lower the humidity before putting it back on.
The fungicide I used was calcium polysulfate. Normally you would use 3 Tbsp per gallon -- I scaled this down to 3/4 tsp per cup, and then cut the dilution further to 1/2 tsp per cup. This works out to a 0.3% solution.
