Do I have to use a Growing Medium? |
|
Using a growing medium is not entirely necessary in hydroponics, but utilizing a grow medium maintains a reserve of nutrient solution in the root zone along with a percentage of air pore space. This can act as a buffer and save crops from failure. The growing systems which rely on grow media are Drip Systems and Ebb & Flow Systems. These systems are most frequently used by hobby and beginning growers as they are more forgiving and provide excellent results.
