Comparison: Best Eb Stone Fish Emulsion With Kelp (Updated | Nov 30th)

Think about the size of your garden and how frequently you plan to fertilize; a quart is ideal for small containers or occasional use, while a gallon offers better value for larger beds and regular applications. Also compare the concentration and recommended dilution rates, as larger containers may have slightly different mixing instructions. Finally, check if the product includes additional ingredients like fulvic acid, which can enhance nutrient uptake.

Most of the emulsions have a balanced N‑P‑K profile around 2‑3‑1, but the powder version offers a higher nitrogen ratio of 12‑2‑2 for aggressive foliage growth. The liquid concentrates with kelp typically provide a more moderate blend that supports both vegetative and reproductive stages. Review the label for exact ratios to match your plant’s growth phase.

Fish emulsions naturally have a strong smell, but some products, like the Alaska Fish Emulsion, are deodorized with natural wintergreen to reduce the odor. Powdered formulas, such as the 12‑2‑2 fish emulsion powder, also emit less scent because the fish material is dried. If indoor use is a priority, choosing a low‑odor or powder option can improve comfort.

Kelp supplies micronutrients, hormones, and trace minerals that boost root development and stress tolerance, while fulvic acid chelates nutrients, making them more readily absorbed by plant roots. Products that combine both, like the Fish Emulsion with Kelp & Fulvic Acid, often deliver faster growth and higher yields. These additives can be especially valuable for nutrient‑poor soils or high‑yield gardening.

Liquid concentrates are convenient for quick mixing and immediate application, but they usually cost more per ounce of nutrient. Powdered emulsions, such as the 12‑2‑2 fish emulsion powder, are highly concentrated and can be mixed to feed up to 100 gallons of water, offering a lower cost per application. Calculate the total amount of usable product you need for your garden size to determine the most economical choice.

Several options, including the GS Plant Foods Liquid Fish & Kelp Fertilizer and the OMRI‑listed Fish & Kelp Fertilizer, carry organic certifications that allow use in certified organic plots. Look for OMRI or other organic labeling on the packaging to ensure compliance with organic standards. Certified products also tend to avoid synthetic additives, which can be important for soil health.

For houseplants, most liquid emulsions recommend 1–2 tablespoons per gallon of water applied every 2–4 weeks. Outdoor vegetables and fruiting plants often need ¼–½ cup per gallon of water, while lawns may require 2–4 ounces per gallon to cover larger areas. Always start with the lowest recommended dilution and adjust based on plant response.

Store liquid emulsions in a cool, dark place with the lid tightly sealed to prevent oxidation and odor loss; many products remain potent for up to a year. Powdered fish fertilizers should be kept in airtight containers to avoid moisture absorption, which can cause clumping. Proper storage ensures the nutrients stay stable and ready for each feeding cycle.
