Believe it or not, the soil itself isn’t necessary for growing plant. You only need some of its constituents. The main reason people grow plants in soil is one, soil acts as a reservoir that retains water and other nutrients. And second it gives the much-needed support to the roots. So if you can provide these two things without using the normal soil you are good to go. Today’s article is all about various soilless media that can be equal or even better than soil in these respects.
What is Soilless Media?
A soilless medium is a single or a mix of growing media that is used to grow plants. The most important point here is that it does not include soil. Soilless media generally do not contain bacteria or fungi so they are considered as sterile media.
