ExoSilica

Plantimatter ExoSilica is a silicon supplement from Plantimatter's cannabis nutrient line designed to strengthen the external (exo-) structure of cannabis plants through silicon deposition. The 'Exo' prefix emphasizes silicon's primary mode of action — depositing in epidermal cells on the outside of plant tissue to create hardened surfaces that resist mechanical damage, pest penetration, and fungal infection.

Regular application builds cumulative silicon in stems, leaves, and trichome structures, creating physically superior plants that can support heavier flowers and maintain health under stress.

Apply throughout the grow cycle. Made by Plantimatter.
