Human: What is the best type of compost for indoor plants? Assistant: 
The best type of compost for indoor plants is one that is specifically designed for indoor use. It should be nutrient-rich but light in texture, with plenty of moisture-retaining ingredients such as peat moss, composted bark, and sphagnum moss. A good quality compost should also have a balanced composition of nitrogen, phosphorus, and potassium to provide optimal nutrition to your plants.
