Frequently Asked Questions
Q: Is Tidal Grow® SeaPhos® a fish hydrolysate fertilizer or a fish emulsion fertilizer?
A: Neither. Tidal Grow® SeaPhos® is a cold-processed seafood hydrolysate fertilizer made by upcycling a variety of fish and other seafood byproducts, such as fishbone and crab shell. Most fish fertilizer products on the market today only include fish byproducts in their formulations.
Q: What is the difference between a hydrolysate fertilizer and an emulsion fertilizer?
A: Fish emulsions can be heat-treated and lose many essential nutrients, but hydrolysates tend to retain all the natural compounds from the fish and other seafood, like amino acids, peptides, lipids, and enzymes, making them more bioavailable. Our proprietary cold process always preserves the full nutrient profile, offering a reliable solution for improving soil and plant health.
Q: Will Tidal Grow® SeaPhos® mix and stay suspended with other inputs?
A: Tidal Grow® SeaPhos® should not be mixed with other mineral fertilizers but can easily be mixed with Tidal Grow® Oceanic®.
Q: Can Tidal Grow® SeaPhos® supply all my phosphorus need?
A: While many growers supplement their existing fertilizer program with Tidal Grow® SeaPhos®, some growers successfully use it as their primary phosphorus source. We suggest you work with an agronomist or a Tidal Grow AgriScience representative for specific application rates and timing recommendations to best fit your operation.
Q: Can I apply Tidal Grow® SeaPhos® with a streamer bar?
A: Yes, growers can successfully use Tidal Grow® SeaPhos® with streamer bars on various row crops.
Q: Can I draw from a tank or tote of Tidal Grow® SeaPhos® without agitation?
A: Just like with many other crop inputs, you need to agitate Tidal Grow® SeaPhos® to keep the valuable nutrients, such as oils and proteins, in suspension before drawing from the tank or tote. We recommend agitating it at least once a month to maintain its quality.
Q: Why do I see a separation of the oils in Tidal Grow® SeaPhos®?
A: Separation is normal and expected because Tidal Grow® SeaPhos® is full of oils and omega-3s that feed beneficial fungi to help improve soil quality through expanded hyphal networks. If storing for an extended amount of time, agitate it monthly, and during the application period, agitate daily to prevent clogging screens and nozzles. For more information, refer to our Mixing Success document.
Q: Will Tidal Grow® SeaPhos® flow through normal high-speed planters? What about high-speed ground rigs and sprayers?
A: Yes, Tidal Grow® SeaPhos® can flow through normal high-speed planters, high-speed ground rigs, and sprayers, but some equipment adjustments are necessary to prevent plugging issues. Inline orifices and screens should be oversized by 40% or more, and pump screens should be between 50-80 mesh. Additionally, reducing pressure and ensuring proper tank agitation is critical. For more details, refer to our Mixing Success document.
Q: Will Tidal Grow® SeaPhos® freeze during the winter?
A: We typically do not see Tidal Grow® SeaPhos® freeze into a solid block, but it may become slow and slightly thicker in cold temperatures. We do not recommend applying Tidal Grow® SeaPhos® when it’s in this cold, viscous state, as it can affect flowability and cause issues with application equipment.
Q: Is there an ideal order for mixing Tidal Grow® SeaPhos® in with other inputs?
A: Similar to other crop inputs, we recommend a specific mixing order when blending with other products. Below are the steps and order we recommend: 1.) Prepare Acidified Mix Water: Use your choice of acid to adjust the mix water pH to 4-5, 2.) Agitate the Mix Water: Ensure the water is well-agitated, 3.) Add Products: Introduce your intended blend of products, starting with the lowest pH (most acidic) and moving up to the highest pH (least acidic). For more details, refer to our Mixing Success document, and always perform a jar test before mixing large volumes.
Q: Does Tidal Grow® SeaPhos® contain chitin?
A: No, Tidal Grow® SeaPhos® does not contain significant levels of chitin.
Q: Does Tidal Grow® SeaPhos® contain chitosan?
A: No, Tidal Grow® SeaPhos® does not contain measurable chitosan. However, our seed treatments, crop protection, and plant health products do contain precisely formulated chitosan.
Q: Are there specific shipping requirements for Tidal Grow® SeaPhos® that I need to know about?
A: Tidal Grow® SeaPhos® is registered to be shipped and sold in the main 48 states of the U.S. and Canada. While Tidal Grow® SeaPhos® is not considered to be a hazardous material, it’s still important to follow all shipping and transportation laws that apply to your business. Tidal Grow® SeaPhos® can be delivered by tanker truck or 265-gallon totes.
Q: Is Tidal Grow® SeaPhos® the same product as Pacific Gro SeaPhos?
A: Yes, Tidal Grow® AgriScience acquired Pacific Gro and all its products, including SeaPhos®. There have not been any changes to the product, manufacturing or formulation.

This episode of Cutting the Curve explores the persistent challenges and emerging solutions in nitrogen management for row crop producers. Host Damian Mason is joined by Trey Cutts and Galynn Beer from Tidal Grow to discuss how traditional practices like fall-applied anhydrous ammonia contribute to nitrogen inefficiency and loss. They introduce alignN, a foliar-applied nitrogen technology designed to improve timing, uptake efficiency, and flexibility. Backed by field trials—including at Mason's own farm—alignN offers a practical tool to align nitrogen delivery with crop demand, reduce overall application rates, and enhance ROI, particularly in a volatile economic environment.
Protect Precious Nitrogen Investments with Tidal Grow® alignN® at the Right Place, Time, Rate, and Source Every grower knows the frustration: you invest in nitrogen, only to watch a big portion of it disappear before the crop can use it. Between run-off, translocation, and missed timing, a significant portion of applied nitrogen gets wasted—and with […]
2026 is teeing up to be a challenging year for grain producers due to declining commodity prices and higher input costs, with growers seeking novel solutions like Tidal Grow’s AlignN fertiliser to save money
Tidal Grow AgriScience, a division of Tidal Vision Products Inc., announces today the launch of its intelligent leaf delivery technology innovation, align Technology, a first-of-its-kind foliar applied nitrogen designed to help growers maximize yields while significantly reducing nitrogen waste. Formulated precisely for broadacre crops, like corn, wheat, cotton, and canola, alignN 18-0-0 delivers encapsulated urea nitrogen directly onto and into the leaf, where it is absorbed for maximum uptake and metabolism.
Trey Cutts, Vice President of Commercial Ag Science at Tidal Grow, shares how intelligent leaf delivery technology is helping growers simplify nitrogen management, boost effectiveness, and align with 4R nutrient stewardship practices for the future.
In this episode of The Intentional Agribusiness Leader Podcast, host Mark Jewell sits down with Dr. Trey Cutts, VP of Commercial Ag Science at Tidal Grow Agroscience.
