    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.
