Collection: Shogun

Shogun Fertilisers delivers precision-engineered plant nutrition for every stage of growth — from the first tender roots to the final week of ripening. Formulated by expert plant scientists with carefully balanced NPK ratios and powered by proprietary SmartZEN bio-technology, the Shogun range is built for growers who want measurable, repeatable results.

The full collection spans every stage and every growing medium. Start young plants right with Shogun Start and Katana Roots for strong root development. Fuel vegetative and flowering growth with the Samurai Coco, Samurai Hydro and Samurai Terra lines — complete base nutrients tailored to your chosen medium. Push flowering into overdrive with PK Warrior 9/18, a high-strength phosphorus-potassium booster engineered to outperform old-fashioned PK ratios, and finish strong with Dragon Force for the ripening phase. Support the whole grow with Shogun Silicon for structural strength, Shogun Calmag to prevent deficiencies, Zenzym for root and substrate health, Sumo Active Boost for maximum floral response, and Geisha Foliar for targeted foliar feeding.

Every product is designed to work in synergy — dial in your exact feeding schedule with the Shogun Feedchart Calculator, and follow a nutrient programme trusted by over 1,000 documented growers worldwide, with a 9.7/10 average rating and 400+ verified reviews. Whether you're growing in soil, coco or hydro, Shogun Fertilisers gives you concentrated, high-performance nutrition at every stage — no fillers, no guesswork, just results.
