I am a long-time gardener who enjoys plants of all kinds. I use my own products to support the health and growth of both my terrestrial and aquatic plants.  My knowledge of plant nutrients and their uses comes through growing aquatic and terrestrial plants. This experience is backed by university-level chemistry and biology courses.

I am the second generation to help manage this business. I was lucky to be taught the love of gardening by both my grandmothers and my mother.  My paternal grandmother grew heirloom roses, succulents, and crafted bonsai. My paternal grandmother was a passionate rose gardener.  From my mother I learned about aquatic plants. I have earned degrees in science, mathematics, engineering, and physics.
