Today, we observed our indoor compost. We believe the compost is ready to use in the garden because we noticed that it was really dark, and the biodegradable materials have decomposed and turned into soil. We also noticed that the compost critters have gotten bigger. When we felt of the soil, it was moist and cool. Normally, compost is warmer because the microorganisms are breaking down the materials and turning it into organic fertilizer. Now can use it in the garden as a fertilizer and start a new indoor compost!
