🌱 SHOGUN Sumo Boost Flowering Bio-Stimulant — Guide and Product Information
SHOGUN Sumo Boost is a specialist flowering bio-stimulant developed to help plants respond more effectively during the bloom phase. It is designed to support rapid flower development, stronger overall plant performance and improved crop quality, including aroma and taste potential through enhanced essential oil production.
This product is especially well suited to growers who hand water or mix nutrient solution for immediate use. Where nutrient solution is stored in active hydroponic systems or larger tanks for longer periods, SHOGUN advises choosing the Active version instead for greater in-tank stability.
🌿 What SHOGUN Sumo Boost Does
During flowering, plants often benefit from targeted additives that go beyond a standard base nutrient. SHOGUN Sumo Boost is formulated to stimulate key plant functions linked to flowering performance, helping support growth, photosynthesis, water uptake and enzyme activity when plants are working hard to develop flowers.
- ✔ Supports a focused flowering response from the start of bloom
- ✔ Encourages efficient plant function during demanding flowering stages
- ✔ Helps improve quality characteristics such as aroma and flavour potential
- ✔ Suitable for use alongside a wider flowering feed programme
📦 Available Options and Sizes
SHOGUN Sumo Boost is a variable product available in the following sizes:
- ✔ 1L
- ✔ 5L
- ✔ 10L
The 1L size is ideal for smaller gardens and trial use, while 5L and 10L options are practical for larger growing areas or regular flowering programmes.
💧 Suitable Applications
SHOGUN Sumo Boost can be used both as a root feed and as a targeted foliar spray during flowering. This makes it a flexible option for growers who want routine reservoir or watering can application, with the added benefit of timed foliar support.
It is recommended for hand-watered systems or where nutrient solution is mixed and used straight away. It should not be used with hydrogen peroxide. For growers running active hydroponics or larger nutrient tanks, a more stable in-tank alternative may be better suited.

🛠️ Setup and Usage Tips
For root feeding, add SHOGUN Sumo Boost at 1-2ml per litre to your nutrient reservoir or watering can from the start of the flowering cycle and continue through to harvest. If using as a foliar spray, mix at 2ml per litre and spray the leaves once when flowering begins, then repeat 28 days later. For foliar spraying, maintain a pH between 5 and 7.
Because this product is intended for immediate-use feeding programmes, it is best matched to growers who do not hold nutrient solution for long periods. Always check compatibility within your feeding schedule and avoid combining it with hydrogen peroxide.
