Shogun Fertilisers
Built for British water.
Formulated in Sheffield for the harder tap water most of the UK runs, so growers here need less Cal-Mag correction on top.
Nothing matches all of those filters.
Kits and bundles
Everything needed in one order.
Base feeds
The staple. Everything else goes on top of this.
Flowering boosters
Used through the second half of the cycle.
Root stimulants
For young plants, cuttings and after transplanting.
Flavour and aroma
Precursors for essential oils and pigments.
Cal-Mag and pH control
Correcting the water before the feed goes in.
Enzymes and additives
Everything that is not a base feed or a booster.
Propagation and starters
Mild feeds for seedlings and cuttings.
Shogun — British-made coco and terra feeds
Shogun Fertilisers are made in the UK, which keeps a lid on cost compared to imported Dutch or American ranges without cutting corners on the formula. Samurai Coco A&B uses SmartZen technology for the coco line and Samurai Terra Grow and Terra Bloom use AquaZen for soil and terra growers — two distinct chemistries rather than one feed stretched across media.
PK Warrior 9/18 is a straightforward late-flower PK boost, Katana Roots covers propagation and transplants, and Dragon Force, Geisha Foliar, Sumo Boost and Zenzym round out a full veg-to-harvest additive line. Shogun Silicon and CalMag are the two most commonly paired add-ons for coco growers running RO water. If you want the whole system without picking bottles individually, the Coco Multipack and Terra Multipack bundle the full range for coco or soil respectively at a lower cost per litre than buying separately.
Coco A&B is usually the strongest-value starting point for new coco growers on this site, and the SmartZen and AquaZen technology is Shogun's answer to the pH-stabilising claims made by pricier imported brands.
