Plant Mechanics Super Si is a premium, ultra-concentrated silicon additive formulated with mono-silicic acid and bioactive amino acids to support plant strength, resilience, and productivity. It delivers silicon in its most bioavailable form, ortho-silicic acid, ensuring rapid uptake without affecting solution pH. This makes it ideal for high-performance growers who demand results across soil, coco, and hydroponic systems.
Silicon plays a crucial role in cell wall structure and plant signalling. Super Si strengthens cell integrity, reduces internodal stretch, and promotes upright, vigorous growth even under high-stress conditions. It is especially beneficial in high-output lighting environments or during peak flowering when structural support and stress tolerance are essential. With its pH-stable delivery and nano-particle formula, Super Si delivers all the benefits of silicon without clogging systems or disrupting nutrient balance.
