Frequently Asked Questions

What is Fish Fertilizer 2-4-1 made from?

Fresh North Atlantic fish, processed to retain natural proteins and oils. That processing is also what's behind the product's lack of unpleasant odor.

Does it have a strong fish odor?

No, it's processed specifically to leave no unpleasant odor after application. That's a common concern with fish-based fertilizers that this formulation addresses directly.

Is the nitrogen readily available to plants?

Yes, the nitrogen in this fertilizer is readily available for plant consumption. That means less of a lag between application and visible uptake compared to slower-release nitrogen sources.

How is this different from Fish & Seaweed Fertilizer 2-3-1?

This 2-4-1 product is fish hydrolysate alone with a higher phosphorus ratio, while the 2-3-1 blend adds seaweed for extra trace minerals. Growers wanting just the fish-based nutrient profile should choose this product.

Which case size should I choose?

The 18oz and 36oz cases of 12 suit smaller-scale or retail use, while the 1gal case of 4 suits growers mixing larger batches less frequently. All three concentrates dilute at the same ratio.
