Abstract

The systems and methods herein are directed to a porous ceramic material coated with nano particles, thereby achieving a filtration and absorption environment for a plant growth medium. The plant growth medium is released in a non-toxic state for consumption by plants residing within the porous ceramic material coated with nano particles. The pores are arranged as to store and subsequently release the plant growth medium in a non-toxic state, which is consumed by the one or more plants. The plants are consuming healthier plant growth medium, and thereby grow to be taller and healthier.

Claims (12)

1. A method of growing plants, comprising:

coating porous ceramic material with nanoparticles, the porous ceramic material having a plurality of pores and one or more cavities, the one or more cavities being enclosed by all sides except a top thereof by the porous ceramic material;

placing the porous ceramic material coated with nanoparticles into a plant containment unit;

placing a liquid plant growth medium into the plant containment unit, thereby the plant growth medium contacts an outer surface of the porous ceramic material coated with nanoparticles;

placing one or more plants into the one or more cavities of the porous ceramic material;

absorbing the plant growth medium into the pores of the porous ceramic material coated with nanoparticles, thereby causing the plant growth medium to be exposed to the nanoparticles;

filtering the plant growth medium from the outer surface of the porous ceramic material through the porous ceramic material coated with nanoparticles, thereby removing contaminants from the plant growth medium and enriching the plant growth medium with growth inducing content by exposure to the nanoparticles;

releasing the plant growth medium, filtered and enriched with the growth inducing content, from the pores into the one or more cavities, thereby contacting root systems of the one or more plants; and

wherein the nanoparticles comprise silver, magnesium, and carbon.

2. The method of claim 1 , wherein the porous ceramic material is constructed of at least one of: silicon (Si), zirconium oxide (ZrO 2 ), and aluminum oxide (Al 2 O 3 ).

3. The method of claim 1 , wherein the plurality of pores comprises pores each ranging between 0.20 micrometers to 1.00 micrometer.

4. The method of claim 1 , wherein filtering the plant growth medium comprises sequestering growth hindering contents from plant growth medium in the pores.
