Description
Shogun Sumo Boost is a premium bloom stimulator from Shogun Fertilisers, formulated to maximise flower density, weight and resin production during the peak bloom phase of the growing cycle. We have been recommending Shogun Fertilisers to UK growers since 2017 as a British-developed premium nutrient brand that has earned a strong reputation for product quality and effectiveness in high-performance UK grow rooms.
Sumo-Strength Bloom Performance
Shogun Sumo Boost combines an elevated PK ratio with Shogun’s proprietary SmartZen technology — a blend of amino acids, plant hormone precursors and natural biostimulants that promote exceptional flower mass accumulation during the peak cell expansion phase of flowering. The SmartZen component is designed to optimise the efficiency of every watt of light and every milligram of mineral nutrient your plants receive during flowering, directing more of your growing programme’s inputs toward flower production rather than vegetative maintenance.
Unlike simple PK products that address only the mineral component of bloom nutrition, Sumo Boost simultaneously stimulates the hormonal and biochemical pathways that drive flower development at the cellular level. This multi-mechanism approach — minerals plus biological stimulus — consistently produces denser, heavier flowers with improved trichome coverage compared to mineral-only PK supplementation at equivalent doses.
Feeding Schedule Integration
Introduce Sumo Boost from week two of flowering through to week six, or one week before your final flush. Apply at the manufacturer’s recommended dose alongside Shogun’s base nutrients — Shogun Coco or Shogun Hydro — for a matched Shogun programme. Compatible with other premium nutrient brands as a standalone bloom booster within any existing feeding schedule.
Pairs with Shogun Silicon for improved trichome structural integrity during bloom, and Shogun Dragon Force as a late-flowering finisher. A well-regarded and effective bloom additive from one of the UK’s most respected grow room nutrient brands.
