A good indoor potting mix is usually a mixture of peat moss/Cocopeat, vermiculite, and perlite. This potting mixture retains moisture very well and allows air to circulate through the roots, but they tend to dry out very quickly. Since they do not contain any nutrients, you must provide your plants with a consistent supply of fertilizer.
An outdoor condition best potting mix has 50% garden soil mixed with 50% organic matter like cow dunk compost or vermicompost. This provides good drainage to the soil and soft soil which allows roots to grow properly. Also, it is rich in nutrients.
Cocopeat is made from coconut husk. It is naturally anti-fungal, making it an excellent choice to start seed and indoor potting mixture.
Cocopeat is an excellent medium that can hold the moisture in the pot but does not allow the water to stand in the pot. resulting in protection from root rot.
Perlite is a natural mineral, extracted from the glass. It is simply a form of glass but without sharp edges.
It is used in Potting mix to improve aeration and improving soil texture, keeping it loose, well-draining.
Perlite and Cocopeat in 1:1 ratio is the best for indoor potting mix.
