Dr. Caterina Allera, in her experience as a researcher in the field of soilless cultivation at CREA (Italian Council for Agricultural Research), has explored various cultivation techniques in natural and artificial substrates, which are of great interest due to their higher productivity compared to traditional farming methods. Her research led her to conclude that the complexity of these cultivation systems primarily arises from the interaction between the growing substrate and the nutrient solution provided to the plants.
Currently used substrates retain water and mineral salts, which accumulate in the porous matrix. A high concentration of salts at the root level is harmful to plants, making it essential to conduct complex monitoring to prevent crop damage. Additionally, the porous matrix promotes fungal diseases, necessitating sterilization systems.
These challenges inspired the development of MEAPLANT Innovation, a breakthrough concept that envisions a cultivation substrate capable of retaining the nutrient solution in the form of droplets without absorbing them. This innovation simplifies soilless cultivation techniques by eliminating the complications associated with traditional substrates.
But how can a substrate retain water without absorbing it? The answer came from nature itself—the way water droplets remain suspended on a spider’s web after rainfall provided the inspiration for MEAPLANT’s revolutionary new substrate

Dr. Caterina Allera, in her experience as a researcher in the field of soilless cultivation at CREA (Italian Council for Agricultural Research), explored various cultivation techniques using both natural and artificial substrates, which are of great interest due to their higher productivity compared to traditional farming methods.
Her research led her to conclude that the complexity of these cultivation systems primarily arises from the interaction between the growing substrate and the nutrient solution supplied to the plants.
Currently used substrates retain water and mineral salts, which accumulate within the porous matrix. High salt concentrations at the root level are harmful to plants, making complex monitoring systems necessary to prevent crop damage.
These challenges inspired the development of Meaplant Innovation — a breakthrough concept based on a cultivation substrate capable of retaining nutrient solution droplets without absorbing them.
But how can a substrate retain water without absorbing it?
The answer came directly from nature itself: the way water droplets remain suspended on a spider’s web after rainfall became the inspiration behind Meaplant Innovation’s revolutionary new substrate.
Meaplant Innovation combines advanced soilless cultivation technology with practical everyday use, making cultivation simpler, cleaner and more accessible everywhere.
A patented soilless cultivation system based on an innovative hydrophobic and inert substrate, designed to retain water through surface tension while supporting strong plant growth.
The Complexity of Nature within the Simplicity of Meaplant Innovation

Meaplant Innovation is based on physical mechanisms observed in nature and studied in droplet dynamics, microfluidics, fiber networks and water-retention systems.
Just as droplets can remain suspended on spider webs, natural fibers or hydrophobic surfaces, the Meaplant substrate uses a network of chemically inert threads to retain nutrient solution droplets through the balance between surface tension, fiber geometry and gravity.
The substrate is positioned horizontally with respect to the sprinklers. Because droplets fall from a very short distance, their impact velocity is low, favoring capture by the mesh of crossed hydrophobic threads.
As droplets increase in size and mass, equilibrium is naturally lost: gravity exceeds retention and the excess solution drains back into the tank. This helps reduce the risk of overwatering while keeping water and mineral salts available to the roots.
Simplified representation of the physical equilibrium that allows droplets to remain suspended within interconnected fibers.
These publications do not describe Meaplant directly, but they document physical mechanisms that help explain fiber-based droplet retention: suspension, capture, water collection, impact behavior and controlled detachment.
Bent fibers can retain larger droplets than simple horizontal fibers, supporting the role of geometry in droplet suspension.
Droplets interacting with thin horizontal fibers can remain suspended or detach depending on droplet size, velocity and the balance between retention forces and gravity.
Structured networks show how geometry, fiber arrangement and surface interactions influence water capture, retention and controlled drainage.
A falling droplet can remain attached, detach or split depending on impact velocity, droplet size and fiber thickness. This makes the physics of droplet capture and release visible and immediately understandable.
FLOW-3D simulations visually demonstrate how droplets interact with interconnected fibers: they impact the structure, become captured inside the mesh, spread through the network and finally drain when mass and gravity overcome retention.
Meaplant Innovation applies these physical mechanisms inside a practical soilless cultivation system: a substrate made of hydrophobic, inert threads where droplets remain suspended, roots access water and nutrients, and excess solution returns naturally to the tank.

Where natural physics
becomes cultivation technology.
The drops of water supplied by an irrigation system are suspended on a lattice of threads forming our innovative cultivation substrate, just as water droplets remain suspended on a spider’s web after the rain. The droplets remain fully available to plant roots without the accumulation of mineral salts inside the substrate.
Meaplant Innovation is the only system designed to allow everyone, everywhere, to cultivate a real vegetable garden through an extremely simple cultivation process. Users only need to periodically add water and mineral salts into the tank and activate the irrigation timer, without complex monitoring or continuous maintenance during plant growth.
Meaplant Innovation can also represent an important solution for improving food security in arid regions, areas affected by water scarcity, and densely populated metropolitan environments vulnerable during emergency situations.
Many natural phenomena involve suspended water droplets: dew forming on spider webs, the capture of droplets on cactus spines, or the movement of droplets along plant fibres. These mechanisms have been studied for technological applications ranging from medical microfluidics to fog-harvesting systems used in desert regions.
Meaplant Innovation is the first cultivation system to apply these physical principles in order to make soilless cultivation simpler, more efficient, and accessible to everyone.
Our cultivation substrate is composed of a network of hydrophobic and chemically inert materials. Water and mineral solution droplets supplied through the irrigation system remain suspended on the mesh thanks to the balance between surface tension and gravity.
The videos below demonstrate how droplets supplied by the irrigation system are captured within a mesh of interwoven threads, just as they are inside the Meaplant Innovation substrate. As droplets increase in mass, equilibrium is lost and the solution naturally precipitates back into the tank.

The drops of water, supplied by an irrigation system, are suspended on a lattice of threads forming our innovative cultivation substrate, as you can look on a spider’web after the rain. The drops are completely available for the plant’ roots without accumulation of mineral salts inside the substrate.
MEAPLANT INNOVATION is the only system that allows you to cultivate a real vegetable garden for everyone, everywhere, due to its simplicity of use: it is only necessary to periodically add water and mineral salts into the tank and turn on the irrigation timer, without any particular checks and wait for the plant growth. MEAPLANT can also be an important solution to guarantee food safety in arid areas, with water scarcity and also in large metropolises due to their vulnerability in case of emergency.
Many phenomena in Nature involve trapped drops of water: the formation of dew drops on a spider’s web, the capture of drops of water on the spines of cacti or the movement of droplets on plant fibres. These phenomena have been studied and explored for various technological applications: from microfluidics for medical and electronic equipment, to harvest nets of the water drops from fog in the desert areas. MEAPLANT’s innovation for the first time in history has applied these physical principles to make soilless cultivation simple, efficient and suitable for everyone.
Our growing substrate is made up of a network of hydrophobic and chemically inert substances. The drops of water and mineral salts, fed by an irrigation system, remain suspended on the wires thanks to the balance established between the surface tension of the drops and their weight.
the videos below show how the drops supplied by an irrigation system are captured by a mesh of interwoven threads as happens in our growing substrate. When the drops increase in mass and become greater, they lost their equilibrium and precipitate inside the tank.
