Grow Genius make some of the best-value plant silicon in the UK. Mono Silicic Acid is the one most growers come for: a highly concentrated, genuinely bioavailable silicon that strengthens cell walls, thickens stems and helps plants carry a heavier crop.
The range also covers Water Genius, a wetting agent that gets more out of the nutrients you already feed, Whole in One for powdery mildew, and Green Cleaner for spider mites, whitefly and thrips.
