Sumo Boost. By Shogun. 

If you've ever grown a plant indoors and watched it keel over for no apparent reason, there’s a good chance the culprit was hiding beneath the surface – literally. Dead roots, leftover debris, and a clogged root zone are a bit like trying to build a skyscraper on top of a swamp. Enter Shogun Zenzym – the unsung hero of root-zone hygiene. Developed by the horticultural masterminds at Shogun, this British-made, multi-enzyme formula is designed by actual scientists (the proper sort, not blokes in sheds), including Dr. Callie Seaman, and tested independently to ensure it doesn’t just claim to work – it actually does.

Enables Root Expansion. 

Now, dead roots aren’t just useless; they’re actively hostile. They clog up the substrate, limit oxygen flow, and provide the perfect home for pathogens with bad intentions. Shogun Zenzym tackles this root-zone gunk like a biochemical SWAT team. Using a precise blend of cellulase, xylanase, pectinase, and glucanase – enzymes that sound like they belong in a space shuttle but actually come from years of biochemical research – Zenzym disassembles dead plant material at the molecular level. The result? Fresh space for root expansion, improved airflow, and the kind of pristine root environment that lets your plants stretch out and thrive like they’ve just had a spa weekend.

Increased Nutrient Uptake.

But there’s more to Shogun Zenzym than just housekeeping. This is not some one-trick pony – it’s a metabolic magician. While it's pulverising the leftover root debris, it’s also performing hydrolysis – a process that breaks the nutrient bonds in that dead material and releases them back into the substrate. This turns formerly locked-away nutrition into accessible minerals and sugars. Essentially, it recycles plant matter into usable fuel, without you needing to add more fertiliser. Think of it as converting yesterday’s waste into tomorrow’s growth – clean, efficient, and far more satisfying than pouring money into more additives.

A Resilience to Disease.

The benefits don’t stop at the roots. With Shogun Zenzym, you’re also feeding the good guys – the beneficial bacteria living in your substrate. These microbial allies thrive on the sugars Zenzym releases, boosting their ability to colonise roots and defend against nasties like pythium. If your indoor grow space has ever fallen victim to root rot or poor nutrient uptake, chances are those little microbes weren’t happy. Zenzym changes that. It fosters a living, breathing, biologically vibrant root zone that’s far more resilient to stress and infection.

Freshens Your Substrate Like New. 

Shogun Zenzym also happens to be indispensable if you're reusing your media. Whether you’re in coco, soil, hydro or running active drip systems, Zenzym refreshes your substrate like new. No more binning bags of old medium after every cycle. It breaks down the lingering biological junk and turns it into food. This isn't just cost-effective; it's also better for the planet. And for those with recirculating systems, there’s the added bonus that Zenzym actively prevents the formation of biofilms, keeping your pipes and drippers free-flowing and functional.

Powerful Biostimulant.

Most importantly, Shogun Zenzym is not a nutrient – it’s a biostimulant. It complements your regular feed schedule rather than complicating it. Use it at just 2.5ml per litre from veg through to final flush and watch your substrate come alive – sometimes literally. Keep your solution’s pH under 7, maintain a warm environment post-application, and the enzymes will do the rest.

Maximum Efficiency. Maimum Yeild.

If you’re aiming for a productive, low-maintenance grow with maximum efficiency, there’s absolutely no reason not to make Shogun Zenzym a staple in your nutrient arsenal. Because no one has time to battle invisible rot when they could be watching their plants rocket upwards instead.
