Nakajima-style fine bubble equipment for facility horticulture

What are the reasons fine bubbles are effective in hydroponics?

Fine bubbles (micro and nano bubbles) are a technology that fundamentally improves the root zone environment of plants in hydroponics, including soilless cultivation, drip cultivation, and NFT (nutrient film technique) cultivation. 1) Stabilization of oxygen supply in the root zone Fine bubbles maintain **high concentrations of dissolved oxygen (DO)** in water for extended periods, making it less likely for roots to suffer from oxygen deficiency and suppressing root rot. This is particularly effective during high-temperature periods and in recirculating systems. 2) Improved nutrient absorption efficiency Microbubbles come into contact with the root surface, promoting nutrient absorption through the activation of root hairs. Growth remains stable without increasing electrical conductivity (EC). 3) Root health and disease suppression Maintaining healthy white roots prevents anaerobic conditions in the root zone, creating an environment where pathogens are less likely to proliferate. 4) Growth promotion and yield stability Initial growth is rapid, reducing growth variability and stabilizing yield and quality.
