I've had some feedback from people who don't understand the difference between aeroponics and ultraponics. I'll try to clarify my choice of ultraponics.

These two methods are derivatives of hydroponics. They involve suspending plant roots in an environment where a nutrient-rich mist is periodically delivered directly to the root zone. This design ensures that plants receive a highly oxygenated nutrient solution while maintaining optimal humidity levels. The absence of a growth medium reduces the risk of disease transmission and minimizes substrate costs. Compared with traditional cultivation, both systems reduce water consumption, and avoid soil contamination (for crops using pesticides and fertilizers).

To obtain a nutrient mist, there is either aeroponics, which uses a high-pressure pump coupled with nozzles to create the mist. This system has already proved its effectiveness, but it is often expensive and uses a lot of electricity.

Ultraponics, on the other hand, uses piezoelectric discs to create the fog. The ultrasonic spraying process consumes relatively little electricity, making it an attractive option for sustainable agriculture. And the disks are very affordable, reducing the cost of the system. But there are far fewer articles on this method. And a lot of questions like: Is the particle size sufficient for the root system?

That's why I'm working on an ultraponic system inspired by medical inhalation respirators that use mesh discs with a frequency between 100kHz and 130kHz.
