Made with a unique cold process that protects all the vitamins, amino acids and enzymes, Neptune’s Harvest retains the micro and macro nutrients naturally found in fish. Plus the seaweed increases plant resistance to early frost, heat and lack of moisture. Because fish and seaweed build the natural sugar in fruits and vegetables, growers report increased yields and improved shelf life. Also great for house plants, outdoor plants, flowers and seed germination. A compost enhancer, too. OMRI listed.
