Pacific Gro Sea Phos (now transitioning to the Tidal Grow brand) is a highly bio-active liquid phosphorus fertilizer that supports root development, flowering, fruiting and reproductive growth through the growing cycle. The formulation is unchanged; only the branding is moving to Tidal Grow.
Made from salmon and fish bone and stabilized with phosphoric acid, it delivers plant-available phosphorus in a biologically active liquid form. Its cold-processed manufacturing method preserves natural compounds and biological activity that are often lost in conventional heat-processed fertilizers.
Key things we want you to know
Best timing: Early season for roots, during flowering for fruit and flower set, and late season in orchards, vineyards and berries.
Dilution: 10:1 to 30:1 for general use. Never less than 50:1 for foliar sprays.
Shipping: Bottles cannot be sealed airtight. Minor seepage in transit is normal and does not affect quality.
Certifications: OMRI Listed, CDFA Certified Organic Input Material

Shipping Notice
This product cannot be sealed in an airtight container because of natural pressure buildup during storage and transit. Bottles are packed in protective bags, but minor seepage during shipping is normal and does not affect product quality.
Production Process
Sea Phos is produced from salmon and fish bone seafood processing residuals through a cold-process digestion system. No high-heat evaporation methods are used, which helps maintain a broader range of naturally occurring compounds. The finished product is screened to 150 mesh for compatibility with irrigation systems and sprayers.
