Rhino Skin - one of the best sources of silica
Silica is the second most abundant element in the earth’s crust (oxygen is the most prevalent), but it is missing from hydroponic root zones and fertilisers. That is a cause of concern because your plants desperately need silica. They have evolved to take it in 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.
But most hydroponics manufacturers have found it difficult if not impossible to effectively deliver silica to your crops. Silica is the main element in sand. It is very thick and solid. It doesn’t easily dissolve in water. It isn’t easily taken into plants. The scientists who created Advanced Nutrients Rhino Skin knew all this before they started the product design and testing process. That’s why they experimented with many different types of silica, as well as different concentrations and manufacturing methods.
They found that the form of potassium silicate used in Rhino Skin produced the highest crop silicate percentages.
