I took a sample from the dirt in one of my houseplants. I chose this because I want to see what kind of molds may be growing in the dirt (this house plants leaves sometimes turn yellow). I also wanted to compare this dirt sample with a dirt sample that I took from outside the house. I expect that this will have a medium to high amount of mold growth because I have had this plant for a long time and the dirt has likely had many chances to collect molds from the air.
