A material or substance that is chemically inactive or unreactive, meaning it does not naturally contain nutrients or interact with other substances in a way that would change its chemical composition. In cannabis cultivation, inert growing mediums like Rockwool, coco coir, and perlite do not provide any inherent nutrients to plants and rely on external nutrient solutions for feeding. Inert media allow for complete control over nutrient levels and pH, which is ideal for hydroponic or soilless growing systems.

In the Wild — Example
Perlite is inert which is why it improves drainage without introducing any unwanted nutrients to the mix.
