    Frequently asked questions about Perlite
    Yes, Perlite is a complete hydrologic substrate in it's own right.
    The difference is very slight. We do not think that Perlite is necessary, as we use very airy peat in our potting soils. Some growers instinctively prefer to use potting soils with Perlite. Soil mixed with Perlite tends to hold moisture for longer. This can be an advantage if you grow at high temperatures or with a high light intensity.
