Ultra fast acting silicon nutrient - for all plants in all settings Scientifically proven effects (1): Increased strength, growth rates and yield. Increased root mass, leaf size and brix content. Improved resistance to pests, disease and environmental stress: read the evidence here. Works by: Supporting natural plant growth and defences, and by improving nutrient and water usage. Application rates: 0.3ml/10L weekly in solution and 0.5ml/L as a fortnightly foliar spray. Environmental contribution: Increases yield per unit input and can reduce or eliminate the need for fungicides and pesticides. Extremely concentrated formulation dramatically reduces shipping weight, volume and packaging. Grow-Genius mono-silicic is made in the UK with silicon from Scotland, minimising product miles. GG mono is readily biodegradable: 95 % over 28 days (method: OECD Test Guideline 301F).
