When it comes to growing plants, the type of growing media you use is very important. There are many different options available, each with its own advantages and disadvantages. Let's take a look at some of the most popular types of growing media:
Soil is probably the most common type of growing media. It's natural, and the base for organic gardening. It can also contain many organic amendments and nutrients that plants need to thrive. A good soil is teeming with microorganisms that break down organic matter into plant-available nutrients. Truly living soils, like Great Lakes, is more nutrient dense and can last a whole harvest or around 90 days.
Other types of growing media can also be made from plant material. Coco coir is a great example of this type of growing media. It's made from the fibrous husks of the coconut. It has an optimal air to water ration and is practically impossible to overwater.
Clay pebbles or LECA (lightweight expanded clay aggregate) are made from fired clay. These materials are lightweight and porous, which makes them a good choice for hydroponic gardening.
One of the most popular types of hydroponic growing media is rockwool. Rockwool is made from spun basalt or volcanic glass. It's very absorbent, water-retaining and a great hydroponic growing media for fast plant growth.
Soilless growing media can refer to hydroponic growing media, like clay pebbles, perlite, vermiculite, or peat moss. Soilless media doesn't contain any soil and is used to provide a structure for plant roots to grow in. These are great choices for indoor or outdoor gardening.
