Dyna-Gro is an American plant nutrition brand established in 1983, specializing in concentrated liquid fertilizers and supplements for hydroponics, soil, and soilless cultivation. Originally developed around hydroponic nutrient research, its formulations provide balanced macro- and micronutrients to support plant growth, flowering, and overall health. The brand is recognized for its complete mineral nutrition approach, incorporating essential nutrients into easy-to-use liquid concentrates rather than requiring growers to combine multiple fertilizers. Dyna-Gro has served home gardeners, greenhouse growers, and professional horticulturists for decades, with its nutrient formulations now marketed under the SUPERthrive brand.
