· Since a large part of silica in plants is deposited in the cell wall, cell wall polymers are the obvious suspects for facilitating silicic acid condensation and polymerization. Monosilicic acid in solutions above saturation spontaneously reacts to form oligomeric silicic acid, preferentially cyclic species.

Silica is revered as a wonder product in a few house plant groups, but then, so is SuperThrive. In reality, there are very few products that will boost your house plants by themselves. The (disappointing) truth is that house plant care requires balancing everything, and making sure your plant has EVERYTHING that it needs.

The codeposition of silica and metals (e.g., Al, Mn, Cd) in solution (in soil and the root system) and in the plant results in reduced concentrations of free, toxic level of metal ions in plants. The silica-precipitated metal ions are not easily translocated, reducing their potential toxic effects on the plant ( Richmond and Sussman, 2003 ; Ma et al., 2004 ).
