PK Warrior 9/18. By Shogun. 

Let’s not pretend there aren’t a million bloom boosters out there, each promising you harvests the size of beach balls. But SHOGUN PK Warrior 9/18 doesn’t need to shout from the rooftops. It just works. Developed by the same team of horticultural heroes who brought us some of the most respected hydroponic innovations in the UK – and driven by the ever-impressive Dr. Callie Seaman – this is a serious piece of grow room artillery. From the smallest grow tents to full-blown agricultural facilities, PK Warrior 9/18 has one job: supercharge flowering, pack on weight, and do it scientifically.

For Warrior Flowers. 

The secret sauce lies in the name – the 9/18 ratio. While everyone else is still faffing around with a 13/14 mix, SHOGUN have dared to be different. Why? Because your base nutrients already contain enough phosphorus to sink a battleship. What they’re usually lacking is potassium – the sugar-stimulating, weight-building powerhouse that gives your flowers their final punch. SHOGUN PK Warrior 9/18 shifts the balance with a precision dose of phosphorus and a double tap of potassium, delivering immediate bioavailability through high-grade agro-minerals and organic acids. The result? Plants that don’t just flower – they erupt.

Dense Floral Clusters.

This isn’t some “use-it-for-a-week-and-hope” formula either. The clever scientists behind PK Warrior have calibrated it for longer use during the mid-to-late flowering window – from week four right up to the final flush. This longer application window isn’t just convenient – it’s productive. Plants experience a second wind, surging forward in their reproductive phase rather than fizzling out. You’ll notice this in the thickening calyxes, denser floral clusters, and a visible jump in final yield weight. When paired with SHOGUN Sumo Boost, things get positively outrageous.

Richer Flavours. Bigger Aroma.

And while most companies would stop there and slap a sticker on the bottle, SHOGUN went further. PK Warrior 9/18 includes 6.8% sulphur – the often-forgotten fourth nutrient. This isn’t just a filler. Sulphur drives amino acid formation, boosts metabolic function, and enhances the taste and smell of your flowers. Without it, nitrogen uptake slows, plant processes stumble, and results suffer. With it, you get stronger cell walls, richer flavours, and the kind of vibrancy that turns heads.

SmartZen Technology. 

There’s also the not-so-small matter of SmartZEN, SHOGUN’s proprietary nutrient delivery technology. This patented system enhances chlorophyll density, improves root hair development, and helps plants manage abiotic stress – meaning they’re healthier, hardier, and more efficient across the board. It’s not fluff. It’s tested, third-party verified, and exclusive to SHOGUN in the UK and Europe. You literally won’t find it anywhere else.

Made In Great Britain.

Versatility is the cherry on top. Whether you’re growing in soil, coco, or hydro, SHOGUN PK Warrior 9/18 fits seamlessly into your regimen. A low application rate of 0.5–1.0ml per litre means a single bottle stretches far, making it incredibly cost-effective. And because it’s manufactured in Great Britain under strict quality control, you know you’re not getting some back-shed brew with a fancy label.

Not Just Another Bottle.

If you’re serious about yield, density, and doing things properly – no guesswork, no gimmicks – SHOGUN PK Warrior 9/18 is an essential tool in your nutrient arsenal. It’s scientific, it’s powerful, and it’s built by people who understand the game from root to fruit.
