Growth Technology Rootzone 1L

Root health drives everything that happens above ground. A well-developed root system takes up water and nutrients more efficiently, recovers from stress faster, and provides the structural foundation for productive vegetative and reproductive growth throughout the entire crop cycle. GT Rootzone is an organic-based biostimulant developed over five years and more than 100 trials, formulated to support healthy root development and root zone activity from propagation through to the end of the grow.

The formulation combines marine extracts, amino acids, thiamine, fulvic acid, and potassium in a concentrated blend that works across several mechanisms simultaneously. Marine extracts supply natural plant growth hormones, particularly cytokinins and auxins, that directly stimulate root initiation and proliferation. Amino acids reduce the metabolic energy the plant needs to synthesise proteins, freeing up resources for root and shoot development. Thiamine (vitamin B1) supports root growth and stress tolerance, particularly in transplants and cuttings under establishment stress. Fulvic acid improves nutrient uptake efficiency and bioavailability at the root surface, while potassium supports the enzyme activity and water regulation that underpin healthy root function. Together the blend also contributes to improved resistance to pest and disease pressure by fortifying cell structure and supporting the plant's natural defence responses.

Highly concentrated: use at 0.5 ml per litre for cuttings and seedlings, increasing to 1 ml per litre for established plants. Apply at every watering throughout the full growth cycle, year-round. Use alongside your regular nutrient programme rather than as a replacement. At the standard dose, a 1L bottle treats up to 1000 litres of solution.
