Silicon (Si)

Marijuana Horticulture

by Jorge Cervantes

Silicon is readily available in most soils, water, and as far as I know, it does not cause cannabis any complications due to deficiencies or excesses.

Silicon is absorbed by the plants as silicic acid. Silicon assists in keeping iron and manganese levels consistent. It is found mainly in the epidermal cell walls where it collects in the form of hydrated amorphous silica. It also accumulates in the walls of other cells. Adequate and soluble silicon guarantees stronger cell walls that resist pest attacks and increase heat and drought tolerance.

A lack of silicon has been proven to decrease yields of some fruits and cause new leaves to deform.

Pests and diseases have a difficult time penetrating the plants that are sprayed with a silicon-based repellent / insecticide.
