Here’s the truth about
your fish fertiliser.
Most fish tonic is cooked above 80°C — and the heat strips out the parts that make fish worth using. Seafuel is never heated. A true cold-processed hydrolysate, so all of it stays in the bottle.
A fish input is only as good as what survives the process.
Fish and kelp are packed with the compounds plants respond to — amino acids, growth hormones, oils and living biology. But most products cook that raw material at high heat to strip and sell the oil. What reaches your plant is the thin, simplified leftover. Seafuel keeps the whole payload intact, so the plant actually gets what fish and kelp were supposed to deliver.
Intact kelp hormones trigger the plant to push more shoots, more flowering sites and finish faster — the outcomes growers actually get paid for.
Living microbes and fulvic acid build soil biology and unlock locked-up minerals, giving you stronger roots, better structure and more resilient plants.
At 0.5–1 ml per litre, a single bottle does the work of a shelf full of separate additives — far less cost per litre than running four products.
Same fish. Completely different process.
There are two ways to turn fish into fertiliser. The difference is heat — and heat decides what actually survives to reach your plant.
The industry’s most common method. Fish waste is boiled to extract and sell the oil. That same heat cooks off proteins, hormones and biology — leaving a thin, simplified product. Typically made from leftover heads and frames, so it’s lower in the phosphorus and calcium held in the bone.
Whole Southern Blue Fin Tuna, enzyme-digested cold. Nothing is cooked off, nothing is stripped out. You keep the full amino acid profile, omega oils, kelp hormones, minerals and living microbes — everything the plant can actually use.
A true hydrolysate — not an emulsion. We keep what others cook off.
Three sources. Hundreds of compounds.
Each source carries a full payload. Here’s what each one actually does inside the plant.
Amino acids are the building blocks of protein — the plant absorbs them directly and skips the energy cost of making them from scratch, so more energy goes into growth. The omega oils act as natural wetting agents. Because it’s whole-fish and cold-processed, you also get the phosphorus and calcium from the bone that thin emulsions lose in cooking.
These are plant growth hormones — the actual signals that tell a plant what to do. Auxins drive root development. Cytokinins trigger cell division and new shoots. Gibberellins push stem and flower-site development. This is the mechanism behind more spikes, faster timing and higher flowering-site counts. Heat destroys these hormones; cold extraction keeps them working.
Fulvic acid is a natural chelator — it bonds to minerals like calcium, iron and zinc and shuttles them straight through the cell wall. Its molecules are small enough to enter the plant directly, so nutrients that would otherwise sit locked in the soil actually get used. Because it works in both acid and alkaline conditions, Seafuel performs in any medium or system.
Plus 10 vitamins & natural antibiotics — all in one bottle.
A little goes a long way.
| Hydro / recirculating | 0.5 ml / L |
| Soil / run-to-waste | 0.5–1 ml / L |
| Worm tea / organic | 10–20 ml / L |
| Foliar spray | 25 ml / 10 L |
Run the whole cycle. Stop only at flush. Don’t reduce your base fertiliser — Seafuel works alongside it.
Complete. Not complicated.
Fish, kelp and fulvic acid — cold-composted, kept alive, in one bottle. Give it a run against your current input and watch the difference in your own room.
