MFL MarMac students in both the high school and elementary school are learning more about hydroponics thanks to a $2,000 McElroy Grant.
Third grade teacher Jennifer Wilwert and high school agriculture teacher Sarah Wille applied for the grant together, for a project entitled “Introducing Hydroponics to Future Farmers,” after learning they both had an interest in sharing the unique plant-growing method with their students.
“Hydroponics is growing plants without the use of soil,” Wille explained.
Instead, aerated water circulates around the plants’ roots and liquid fertilizer provides the nutrients they would otherwise receive from soil.
