      Humboldts Secret

      Humboldts Secret Supplies begins with the story of Ben. He was known for producing the best flowers in Southern California. Ben saw a need in the nutrient additive marketplace. He wanted to make an additive so good that it could be used as an All-In-One additive, consolidating multiple additives into one. After a lot of hard work he developed Golden Tree. The name made sense, because any tree that got a taste of it would turn to gold for the grower.

      Since Golden Tree, HSS has emerged as one of the major plant nutrient manufacturers and suppliers to hydroponic/agricultural distributors in the United States. We are waiting to hear from you. Become a friend of ours today.
