As an alternative verticulture (vertical farming), plants are housed in ceramic 3D-printed multilevel towers. The system integrates solar-powered atomizers to recycle and deliver nutrient-rich water to the roots of the plants. Micro-droplets of water are periodically circulated in a low-pressure and closed loop configuration to create a rich misted environment inside the towers conducive to the plants’ growth. Within this innovative approach, which leverages the aeroponic concept, plant roots are suspended in the air inside ceramic 3D printed enclosures, receiving periodic sprays of a nutrient-dense solution. While technically the roots of the plants are openly hung in the air inside the hollow ceramic 3D-printed growing champers, the leaves are exposed to the indoor/outdoor ambient environment for a better photosynthetic response.
ClayPonic V1 enables year-round cultivation with minimal water and nutrient consumption by maximizing plant nutrition assimilation and accelerating growth. The deployability merit of the model facilitates its placement and integration into the built environment in urban centers and around human settlements, reducing transportation costs and bolstering local economies. The verticultural configuration of the model and its soil-free nature significantly reduces risks of soil-borne diseases, pathogens, and pests. This revolutionary approach to farming efficiency improves agricultural practices and reduces dependence on chemical pesticides and herbicides, promoting eco-friendly farming principles.
Water culture and working air concept: water circulation and nutrient uptake
Additive Manufacturing Technology, the industrial application of 3D printing, has spurred materials explorations, leading to the development of clay hydroponic farming systems. The computer and printer make it possible to use “particles of light, jets of water, and bits of data” to transform dust into utilitarian outcomes and products. Such transformation involves high means of technical innovation in additive manufacturing and mundane materials such as clay, engaging opposing ends of the technological spectrum. Such a practical fabrication process comprises successive incremental deposition of clay paste, layer by layer, directly driven from 3-dimensional data.
This seamless manufacturing workflow, which spans digital fabrication and machine craft, made it possible to efficiently produce custom, intricate, and modular multilevel ceramic substrates capable of accommodating plant growth. The rapid prototyping capabilities of the technology make it more adaptable, allowing for effective custom adjustments to meet the requirements and circumstances of clay hydroponics. Localization of production and material sourcing, in alignment with the sustainable additive manufacturing practices, addresses issues of supply chain and contributes to the affordability and adoption of farming technology.

ClayPonic V1 takes advantage of a novel, inexpensive, and locally harvested clay as a prime material for fabrication. Clay is low-cost, widely available, and environmentally benign with little to no ecological footprint. A key advantage of the material in juxtaposition with additive manufacturing lies in the unparalleled design and production flexibility. Perhaps the most favorable attributes that align with clay’s potential benefits for plant growth and development is its physical, chemical, hydraulic, and geological composition properties. The slow absorption and release of water by ceramic helps maintain a level of moisture in the rhizosphere, preventing both waterlogging and drying. This reduces water circulation frequencies and over-reliance on atomizers. Its aeration porosity helps to oxygenate plants’ root zones. Furthermore, clay’s ability to enhance plants’ nutrient uptake is superior to that of other commonly used materials in hydroponics.
Introducing 3D printed ceramics as growing mediums along with the working air maintains a high rate of photosynthesis by managing oxygen levels in the air and around the plants. This condition, coupled with the uniformity of nutrient concentration in the water droplets and pH values accelerates plants growth. The presence of minerals inherent in the clay body can supplement nutrient deficiencies in the soil, contributing to improved crop quality and resilience against environmental stressors. The comparative advantages of clay, in general, over commonly used plastic and other mediums in supporting plant growth warrant exploration regarding their impact on nutrient and oxygen delivery as well as photosynthetic performance.

The introduction of the system as a meditative space amplifies its impact, inviting individuals to engage with nature in a contemplative and immersive manner. Clay 3D Printed Hydroponics offers a wide spectrum of therapeutic experiences by communicating to the soul, mind, and spirit of our bodies through multitudes of sensations: sighting, hearing, smelling, touching, and tasting – the five human senses. From the moment individuals encounter the system, whether in an educational setting or a public space and horticulture garden, they are fully involved in a sensory experience that transcends mere food production.
Visual engagement emerges as a key element of this urban farming model. The vertical configuration of the garden optimizes space and creates a captivating showcase of ceramic elegance and lush greenery. By including a range of plant types including ornamentals and edibles, the pavilion caters to our aesthetic sensibilities while also promoting both biodiversity and food choices. The system not only stimulates touch sensory but also dictates physical engagement through transplanting and harvesting. The system offers olfactory stimulation through the cultivation of fragrant plants. When people engage with the garden, they can smell the scents of herbs and flowers, enhancing their journey and heightening their sensory experience, creating a stronger bond with nature. The auditory dimension allows people to enjoy the musical sounds of water trickling through the ceramic structures. Such spiritual sound not only enhances the ambiance of space, but also acts as a gentle nudge and reminder about the system’s dependence on water — a valuable resource that needs careful handling and preservation.
Clay 3D Printed Hydroponics was deployed as a pivotal pilot project in the Atlanta Metropolitan Area (Fig. 7,8,9). The pilot comprises 100 modular units assembled into variant 20 towers. From June to August 2023, where average temperature, humidity, and rainfall were 77 Fahrenheit, 73%, and 4 inches respectively, 600 seedlings were transplanted and flourished under the system and these conditions. The pilot yielded over 160 pounds of fresh vegetables crucially supplied to local food pantries in the Atlanta Metro Area. The yield, which includes a harvest of cabbage, chard, green sorrel, arugula, lettuce, bibb lettuce, and kale, contributed to feeding over 500 homeless individuals. This pilot project marks a significant stride towards addressing food insecurity as it achieved exceptional performance metrics, notably saving up to 90% of water compared to traditional soil-based cultivation methods, while also requiring 50% less time for cultivation cycle.
