HEALTHIER BUDS, FRUITS & FLOWERS
Sonic Bloom
Sonic Bloom is a liquid phosphorus and potassium-based fertiliser, scientifically designed to promote healthy buds, flowers, and fruit. Its rapidly absorbable nutrients help boost photosynthesis and improve yields for lawns, gardens, and vegetable patches.
Potassium Boost for Flowering and Fruit Development
UltraGrow Sonic Bloom is a potent liquid fertiliser, combining phosphorus and potassium to boost flowering and fruiting. Its fast-absorbing nutrients fuel plants, improving size, quality, and yield in gardens, lawns, and vegetable patches.
Apply Sonic Bloom just before flowering and every two weeks during bloom to support critical growth stages. This formula promotes faster bud development, stronger blooms, and better chlorophyll production, while maximizing photosynthesis for healthy, vibrant plants.
Ideal for flowers or vegetable patches, Sonic Bloom ensures early blooms, higher yields, and efficient nutrient uptake to drive vigorous plant growth.

How to Apply Sonic Bloom

INSTRUCTIONS
- Shake the liquid kelp well before diluting.
- Use within 72 hours of mixing.
- Store in a cool location.
- Minimum dilution rate: 1:50 = 1ml to 50ml of water.
