Passive hydroponics is a way of growing plants without soil. Instead of planting the plants in the ground, we put them in a special container that holds water and nutrients for the plants to absorb. Passive hydroponics is a type of hydroponics that doesn't use any pumps or electricity to circulate water or nutrients.
The plants sit in a container filled with a type of growing media, such as perlite, coconut coir, or vermiculite, which helps them to stand upright. The plants' roots grow into the media, absorbing water and nutrients from the solution below.
The nutrient solution that the plant needs to survive is poured into the container, and it is usually made up of water mixed with a special kind of fertilizer that has all the essential nutrients the plant needs to grow. The nutrient solution is then absorbed by the growing media and the roots of the plant.
Passive hydroponics is a low-maintenance way of gardening because the plants only need to be watered once a week. The plants also don't need to be constantly checked for pests or diseases because they aren't coming into contact with soil, which can often harbor harmful organisms.
In summary, passive hydroponics allows plants to grow without soil by using a special container filled with a growing medium that irrigates the plant with water and nutrients. It's an easy and low-maintenance approach to gardening.
