Shogun Sumo Boost: The Breeder’s Secret for Reproductive Vigor
Successful breeding isn't just about pollen hitting the pistil; it’s about the health and vitality of the reproductive organs. Shogun Sumo Boost is the heavyweight bio-stimulant that ensures your parent plants are performing at their absolute genetic peak.
Based on the natural compound Triacontanol, this formula does more than just swell fruit; it triggers a powerful, targeted flowering response. For breeders, this means more robust flowers, higher pollen production, and the energy reserves needed for developing healthy, viable seeds.
Please note that we currently do not have 1L, 5L, 10L or 25L bottles in stock at our nursery. This is a special order item and requires a 7-10 day processing time before your order is dispatched.
The Science of Seed Production
Maximized Genetic Expression: To select the best phenotype, you need to see the plant's true potential. Sumo Boost up-regulates genes associated with photosynthesis and photorespiration, allowing your parent plants to express their traits fully.
Reproductive Energy: Seed production is energy-intensive. By stimulating cell division and increasing chlorophyll content, this booster helps your plants to support a heavy seed set without exhausting themselves.
Stress Protection: Breeding grow tents can get crowded or run harder. Modified amino acids in the formula act like cytokinins (anti-stressors), protecting your prized plants from heat and abiotic stress during the critical pollination window.
Why It’s a Game Changer for Breeders
Better Seed Viability: Sumo Boost increases the concentrations of Calcium, Magnesium, and Potassium specifically in fruit and flowers.
Enzyme Activity: It stimulates enzyme activity and protein synthesis, which are the building blocks of life required for successful fertilisation and seed maturation.
Revive Stalled Projects: It can be used to stimulate growth in stressed or under-performing crops to get your breeding project back on track.
How To Use
Root Feed: Add 1-2ml per litre to your reservoir or watering can as soon as the flowering cycle starts. Continue throughout the seed-setting phase until harvest.
Foliar Application: Mix 2ml per litre (pH 5-7) and spray leaves. Apply once when flowering starts, and again 28 days later.
Important: Preservation MattersDo not use Shogun Sumo Boost with Hydrogen Peroxide (H2O2), as it will degrade the organic bio-stimulants.
How to use
Do not use with hydrogen peroxide.
Root feed at 1 to 2ml per litre from the start of flowering
Continue through the seed-setting phase until harvest
For a foliar spray, mix 2ml per litre at pH 5 to 7 and spray the leaves
Apply the foliar spray once when flowering starts and again 28 days later
