How Shogun Sumo Active Boost Works

The team at Shogun set out with a simple, yet highly ambitious brief: to create the most effective nutrient range on the market for a price that's affordable to every grower. It was a task that required extensive research and development, but after numerous side-by-side tests and detailed analysis of other leading plant nutrition products, they've managed to deliver a range that sits proudly alongside the very finest high-end nutrient lines, and at a fraction of the cost. Connoisseur growers often select flagship nutrients from various companies and combine them to create their ideal nutrient regimen. With Shogun, you can achieve the same effect by simply sticking to their complete range, knowing that each component product has been formulated to compete with the very best alternatives available.

Shogun Sumo Boost took 3 years to develop. One of the ingredients that makes it stand out from the crowd is something called triacontanol at the ideal concentration of 0.05%. Triacontanol is a naturally occuring phytohormone that is found in most plant matter. Blended with other great natural ingredients like fulvic acid, humates, cytokinins, fucoidan, betaine, amino acids, vitamins and polysaccharides, Sumo Boost does your plants a whole world of good! It increases CO2 assimilation, plant respiration, essential oil production, upregulates gene expression, downregulates stress and increases metabolism. It begins to work after just 2 hours after application. Our customers say that they see a huge difference in their plants after just 1 to 4 days. It also has a very positive effect during the vegetative stage. Active Boost differs from regular Sumo Boost, in that it is formulated specifically for amazing results in hydroponics systems, such as flood & drains, recirculating drippers and deep water culture (bubbler) buckets.

Sumo Active Boost is a flowering additive that can be used as a foliar spray or administered through roots. It triggers an explosive upsurge in your plants' metabolism, stimulating essential oil production and adding up to 10% to the final weight! The increased level of oil production also means that you'll have an end product with a much greater depth of flavour. Its powerful bio-stimulators even ensure that your plants develop a healthy resistance to attacks from pathogenic fungi and bacteria by strengthening their immune system during the most critical period of their life cycle.

How To Use

How to Use Shogun Sumo Active Boost

Please note: Sumo Active Boost should be changed out of your reservoir at least every 2 weeks for optimum performance

Shogun Sumo Active Boost can be applied not just in the flowering phase but also during the vegetative stage for increased growth. Stop using it just before you start the final flush (generally 1-2 weeks before harvest). Make up your base nutrient as usual and add it at a rate of 1-2ml per litre of nutrient solution. Check pH and EC levels to ensure that they sit within optimal ranges for your chosen plant species and the stage in its life cycle.

It can also be applied as a foliar feed. Fill your sprayer, add 2ml of Boost per litre of water and pH the solution to around 6.0. Spray directly onto leaves when the lights are off, leaving plenty of time for them to dry out before the lights switch back on again (otherwise you may risk burning). Do this once a week.

As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one.
