Description
Shogun Silicon is a professional potassium silicate supplement from Shogun Fertilisers, providing bioavailable silicon that strengthens plant cell walls, improves structural integrity and enhances resistance to environmental stress, pests and disease throughout the growing cycle. We have been recommending Shogun Fertilisers to UK growers since 2017 as a British-developed premium nutrient brand with a strong reputation for product quality and formulation precision.
How Silicon Builds Stronger, More Resilient Plants
Silicon is absorbed through the roots and incorporated into cell walls and the epidermal cuticle layer of leaves and stems, creating a physical barrier that improves resistance on multiple fronts simultaneously. The thickened cell wall structure increases stem strength and branch load-bearing capacity — an important benefit during flowering when heavy flower development can cause stem bending or breakage without mechanical support. The reinforced leaf cuticle resists penetration by sucking insects including spider mites and thrips, and the same physical barrier limits the penetration depth of fungal hyphae attempting to establish powdery mildew infections on leaf surfaces.
Shogun Silicon uses a potassium silicate formulation providing silicon in the monosilicic acid form that plants can absorb directly through roots, combined with the Shogun SmartZen technology that improves the bioavailability and translocation of silicon to the tissues where it is most needed. Regular application from early vegetative growth through to mid-flowering builds progressively stronger plant architecture that becomes visible in the overall robustness of the canopy.
Application Guidelines
Add Shogun Silicon to your reservoir or feed water before adding base nutrients — silicon is strongly alkaline and should be diluted in water first to stabilise pH before the rest of your feeding programme is mixed. Apply at 0.5–1ml per litre throughout vegetative growth and into the first half of flowering. Discontinue in the final three to four weeks of bloom. Monitor pH carefully after adding silicon as it raises pH significantly at higher doses.
Compatible with the complete Shogun nutrient range. Pairs with Shogun Samurai base nutrients, Sumo Boost and Dragon Force for a complete Shogun growing programme.
