Samurai Terra Grow. By Shogun. 

There’s something profoundly satisfying about watching a plant roar into life during its vegetative phase - leaves pushing out like solar panels, stems thickening like biceps, and roots tearing through soil like a caffeine-crazed mole. And now, thanks to Shogun Samurai Terra Grow, that entire process just got faster, stronger, and more scientifically supercharged. Designed for growers who don’t do half measures, this is the go-to veg nutrient for anyone serious about setting up their plants for outrageous yields later on.

Boost Yields by 8%. 

At the core of Shogun Samurai Terra Grow lies its not-so-secret weapon: SmartZen technology. Not just a catchy name, SmartZen is the horticultural equivalent of nitrous oxide. Developed by actual scientists, not armchair enthusiasts, SmartZen does two critical things - it boosts nutrient uptake, and it ramps up photosynthesis. That means more green, more growth, and more potential packed into every inch of plant matter. The result? Up to 8% bigger yields, backed by data, not guesswork. If you’ve ever wished your plants would get on with it and grow already, Terra Grow is the stuff you’ve been looking for.

Amino Acids & B Vitamins.

But Terra Grow isn’t just about brute growth. It’s a calming force too, especially where young, vulnerable plants are concerned. Seedlings and freshly transplanted cuttings can go into meltdown at the first sign of stress - wilting, yellowing, or just collapsing like a poorly-assembled camping chair. Shogun Samurai Terra Grow has your back here, offering a stress-busting formula laced with amino acids and B vitamins that stabilise your plants and get them through their awkward adolescence without a tantrum. It’s a spa treatment in a bottle - one that toughens up your plants while soothing their nerves.

Nutrient-Dense for Huge Harvests.

Of course, it’s not just what’s in Terra Grow that counts - it’s how well it’s built for the job. With a precise 2.2-1.0-5.0 NPK ratio and a suite of seven micronutrients (including iron, sulphur, and magnesium), Shogun Samurai Terra Grow delivers balanced, powerful nutrition specifically calibrated for soil substrates. Iron and magnesium drive chlorophyll production, keeping your plants green and hungry for light. Sulphur keeps protein synthesis humming, helping your plants build strong cell structures from the inside out. It’s nutrient-dense without being overbearing - like feeding your plants steak instead of junk food.

Dialled in For Heavy Weight. 

Another major win for Shogun Samurai Terra Grow is its adaptability. Whether you’re working with chalky hard water or gloriously soft stuff straight from the mountains, this formula is dialled in for performance. You’ll find precise dosage guidance depending on your water type, and the product’s pH stability ensures your nutrient mix won’t swing wildly into dangerous territory. It’s also compatible with any bloom boosters or additives you might be running, meaning Terra Grow plays nicely with the rest of your nutrient programme without clogging systems or causing salt build-up. This is clean feeding, designed for clean results.

Made in Great Britain.

Finally, Shogun Samurai Terra Grow isn’t just another product on a crowded shelf - it’s the foundation of a growing system engineered by the UK’s top horticultural minds. Independently tested, proudly British-made, and available in a range of sizes to suit the home hobbyist or the industrial-scale farmer, it’s a nutrient built for real-world growers. Pair it with its flowering companion, Shogun Samurai Terra Bloom, and you’ve got yourself a nutrient duo that doesn't just talk a good game - it grows one.
