OMRI-listed organic liquid kelp made from cold-processed Ascophyllum nodosum sourced from the clean North Atlantic waters of Norway provides a concentrated dose of natural growth hormones, including cytokinins and auxins, alongside over 60 trace minerals such as iron, zinc, magnesium, and sulfur. This highly dilutable fertilizer transforms into up to 800 gallons of nutrient solution per gallon of concentrate, helping plants establish stronger root structures, withstand drought or frost stress, and produce brighter green foliage through enhanced chlorophyll activity. Ideal for both outdoor crops and indoor environments, the extract supports faster seed germination and prolongs flowering cycles to maximize harvest volumes for vegetables, fruits, herbs, and ornamental species alike.

Dilute 1.5 to 2 ounces per gallon for weekly foliar sprays, apply 2 to 4 ounces per gallon for soil drenches at the plant base, or mix 1 teaspoon per gallon into hydroponic reservoirs; results improve significantly when applied early morning or late afternoon to align with open stomata and prevent wash-off or midday evaporation. Compatible with various fertilizers, this kelp extract amplifies nutrient uptake efficiency while remaining safe for pets, pollinators, waterways, and all edible plants, including roses, tomatoes, blueberries, azaleas, and pothos. Gardeners seeking added nitrogen support may also consider GS Plant Foods Fish & Kelp Liquid Blend, which pairs these beneficial microbes and NPK 2-3-1 sources with the same Norwegian seaweed extract to create a comprehensive root and growth booster.
