Tiny bubbles, big results: Nanobubble technology

Any time new technology comes into play in controlled environment agriculture (CEA), growers tend to balance optimism with skepticism. It’s an industry where the adage “seeing is believing” often applies. That attitude puts nanobubble technology at a distinct disadvantage.

Typically defined as measuring between 70 and 120 nanometers in diameter, nanobubbles can’t be seen with the naked eye. With one nanometer (nm) equal to just one billionth of a meter, nanobubbles are 2,500 times smaller than a grain of salt. But the visible results experienced by nanobubble researchers and CEA growers put these tiny workhorses in the limelight.
