The ideal growing medium
The ideal growing medium for Hydroponics are, as follows.
- hardened expanded clay
- neoprene discs
Are some of the non-organic mediums or non-mineral soils, used in hydroponics.
What is the difference between soil and soilless medium?
The difference between soil and non-soil mediums is their ability to hold water and oxygen, and their ability to hold onto nutrient ions and supply them to the plant roots as the plants call for them.
When growing plants in soil(s), it’s usually be grown either in containers or out in the field. Realistically, the best setting for growing in a soil-based medium is outdoors. Soilless growing conserves water, it conserves land, and requires less pesticides that increase a farm’s risk of runoff.
Cation exchange capacity, is the ability of a growing medium to hold nutrients on call, for the roots to uptake. The CEC of each medium will affect the pH, for maximum nutrient uptake.
