🌱 SHOGUN Sumo Active Boost Flowering Bio-Stimulant — Guide and Product Information
SHOGUN Sumo Active Boost is a specialised bio-stimulant developed for growers using active hydroponic systems who want a bloom booster that remains stable in the reservoir. It contains the same active ingredients as standard Sumo Boost, but is formulated with a unique emulsion technology to help prevent fermentation in tanks for up to 14 days.
Used correctly from the start of flowering through to harvest, it is designed to encourage a strong flowering response while helping plants make efficient use of water, light and nutrients. It can also be used as a targeted foliar spray at key stages of bloom.
🌿 Why Choose SHOGUN Sumo Active Boost?
This product is aimed at growers running recirculating or active hydroponic setups who need a flowering stimulant that works reliably in a tank environment. It is intended to support growth, photosynthesis, enzyme activity and water uptake during the flowering phase, while also contributing to improved aroma, taste and overall crop finish through enhanced secondary metabolite and essential oil production.
- ✔ Heavyweight bio-stimulant for flowering plants
- ✔ Formulated for active hydroponic reservoir use
- ✔ Supports flowering development and plant efficiency
- ✔ Helps improve quality characteristics such as aroma and taste
📦 Available Options and Sizes
SHOGUN Sumo Active Boost is available in three size options, making it suitable for everything from smaller hobby reservoirs to larger hydroponic systems.
- ✔ 1L
- ✔ 5L
