Simple, easy success.

Emerald Harvest was founded in 2015 in Santa Rosa, California, by industry insiders with decades of experience. Over many years, our founders had listened to the growing community talk about what they wanted and needed from a nutrient line. So, we set out to bring growers superlative yields for significant profits at a reasonable price point while reducing the mess and fuss and waste of other nutrient lines. The result? Our science-backed, streamlined premium base nutrients and supplements for hydroponic plants.

  • Proudly based in Santa Rosa, California
  • Founded after years in the industry
  • Nutrients designed with growers in mind
