  • Humic acid is a notoriously useful ingredient in organic agriculture. Derived from ancient leonardite, this ingredient is known to help breakdown complex nutrient structures for greater plant assimilation.

  • Don’t settle for pseudo-organic inputs! This CERTIFIED organic nutrient line is approved by CDFA, OMRI, WSDA & CleanGreen!

  • Serving as a food-source to grow and strengthen soil microbial communities, adding this into your garden will drastically improve a plant’s ability to uptake nutrients when they need it.

Long ago, before man walked the earth, a strange landscape of pre-historic plants and animals both lived and died under a primordial sun. Layer after layer, their decomposing remains re-united with the earth from which they came. These concentrations of naturally occurring acids transformed as the centuries passed into rich deposits known as “leonardite”. Growth Science harnesses this wonderful gift of nature by providing humic acid derived from leonardite into a product we proudly call… Humic Tonic.
