Shogun Sumo Active Boost — Triacontanol Flowering Stimulant for Active Hydroponics
Best for: Growers running NFT, DWC, flood & drain, or other recirculating hydroponic systems who want stable, fast-acting yield improvement without tank fermentation
Our thoughts
This is the hydroponic-specific answer to the hand-watering Sumo Boost. The 14-day tank stability is genuinely useful — no fermentation, no residue, no guessing. If you're running active systems and want to add something that actually works without overcomplicating your reservoir management, this is one worth considering. Triacontanol-based boosters have become proper mainstream in the grower community, and Shogun's version is properly engineered for the job.
Shogun Sumo Active Boost is a liquid flowering stimulant concentrate based on triacontanol and seaweed extract, designed specifically for active hydroponic systems. Where the original hand-watering Sumo Boost could ferment in recirculating tanks, Active Boost stays stable for up to 14 days thanks to a cutting-edge emulsion formula. It works by boosting cell division, increasing nutrient uptake, and triggering essential oil production — with growers reporting visible results within 2–4 days of application.
How it compares
Shogun Sumo Active Boost sits in the mid-premium flowering additive category, competing primarily against other triacontanol-based products and traditional phosphorus-potassium bloom boosters.
-
vs. PK boosters (Big Bud, Liquid Kool Bloom): Triacontanol works differently — it's a growth regulator, not just extra phosphorus. You get cell multiplication and stress resistance, not just heavier flowers
-
vs. other triacontanol products (British Organic Bio Organic Boost, TriaBooster): Shogun's is optimised for active systems specifically — the emulsion stops fermentation and foaming in aerated tanks
-
vs. hand-watering Sumo Boost: Same active ingredients, different stability profile. This one stays fresh in recirculating systems; the original doesn't
The key difference: it's engineered for tank life, not hand-fed pots. That matters if you're running drip, NFT, or bubbler systems.
Usage guidance
Sumo Active Boost is applied as a root feed throughout the flowering cycle, with optional foliar spraying for faster uptake.
Root feed (reservoir application)
Add 1–2ml per litre of nutrient solution as soon as flowering starts. Early weeks can run higher (1–2ml/L), tapering to 1ml/L by week 8. Stop feeding in the final week. Works in NFT, flood & drain, DWC, bubblers, and any recirculating system.
Foliar spray (leaf application)
Dilute at 2ml per litre of water and spray onto foliage once at the start of flowering, then again 28 days later. Spray early morning or late evening when stomata are open. Target pH: 5–7.
Key compatibility note
Do not mix with hydrogen peroxide. Works with any base nutrient line — it's an additive, not a replacement.

Who this is for
- Growers running active hydroponic systems (NFT, flood & drain, DWC, bubblers) who want a stable tank additive
- Anyone moving from hand-watering to recirculating systems and wanting to stick with Sumo formulas
- Growers looking to boost yields and essential oil production without complicated multi-stage feeding schedules
- Budget-conscious growers who want proven triacontanol performance at reasonable cost, not premium pricing
Not designed for soil or coco hand-watering — use the original Sumo Boost for those applications.
Our take
This is a properly engineered product for a real problem: seaweed-extract boosters that ferment and gunk up your tank lines. Shogun solved it. The triacontanol concentration is ideal, the tank life is genuine, and the results are fast enough that you'll notice the difference in plant vigour within days.
If you're running active hydro and want to add something that won't complicate your reservoir management or waste money, Sumo Active Boost is worth picking up. Good time to buy while clearance stock lasts.
