That element is silica, which is the second most abundant element in the earth’s crust (oxygen is the most prevalent), but guess what? Silica is missing from hydroponics root zones and fertilizers.
This is a cause of concern because your plants desperately need silica. They evolved to intake it so it becomes part of their cell walls.
That’s important because cells are the building blocks of your plants and cell walls are the structural features that determine the strength of your plants’ stems, leaves, flowers, floral structures and metabolism.
Not only do your plants accumulate silicon to build their cells, they also store it as foundational support between cells.
In fact, your plants contain as much as 10% of their weight as silica.
There’s a catch, however-silica isn’t supplied at all in most hydroponics fertilizers or root zone media, and even if it is, it usually isn’t the right type or amount of silica to maximize silica’s benefits.
