Plant Mechanics

Plant Mechanics Super Si

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.

FloraMax

FloraMax Flowering Enhancer

FloraMax Flowering Enhancer is a comprehensive bloom-phase additive formulated to simplify and elevate flowering performance. Combining the power of phosphorus and potassium with calcium, magnesium, and iron, it delivers a balanced nutrient matrix designed to fuel heavy floral development, improve structural integrity, and support nutrient uptake efficiency during peak metabolic activity. This unique 3-in-1 solution replaces the need for separate PK boosters, Cal-Mag supplements, and pH stabilisers. By improving the buffering capacity of your nutrient solution; often by up to 500%, Flowering Enhancer keeps pH locked in the optimal range, preventing lockouts, fluctuations, and system instability. This is especially valuable in hard water conditions, coco media, or when running recirculating hydroponic systems. In addition to promoting denser flowers and stronger stems, Flowering Enhancer also targets common deficiency symptoms such as leaf yellowing, curling, petiole purpling, and poor fruit set. Its clean-running formula integrates effortlessly with all nutrient lines and growing systems, whether hand-watered or automated, soil-based or hydroponic.
