Humboldts Secret has emerged as one of the major plant nutrient manufacturers and suppliers to the hydroponic/agriculture community in the United States, with over 10 years of demonstrated excellence. The company was founded by growers, for growers, with the goal of making high-quality nutrients and delivering them at affordable prices so that you can get maximum results and succeed as growers.

Humboldts Secret's products are unique because they are all made with the finest ingredients and 100% manufactured in their California-based facility, ensuring the highest quality every time. The company is in the business of making growing simpler and easier to succeed at.

Humboldts Secret offers a wide range of products, including Starter Kit + Essentials, Macro Nutrients + Additives, Pest Control + Plant Strength, pH Up & Down, For Home, Lawn, & Garden, and Growing Accessories. Customers can visit the store to explore these product categories and find the perfect solutions for their growing needs, whether they are small or large.

One of Humboldts Secret's flagship products is the CalMag & Iron supplement. This formula is designed to specifically address any plant deficiencies that may be present, as many varieties of flowering plants require higher levels of these micronutrients. The supplement effectively corrects and remedies these micronutrient plant deficiencies, supporting nutrient uptake and absorption.

The CalMag & Iron supplement is suitable for hydroponics, soil, and container gardens, ensuring strong and healthy plants and yields. It is highly recommended for plants growing in coco substrate or reverse osmosis water, as the absorption process becomes magnified.

As the founder, Yousef Benhamida, states, "From grower to nutrient manufacturer, my goal is to make high-quality nutrients and deliver them at affordable prices so that you can get maximum results and succeed as growers." Humboldts Secret is dedicated to providing the best possible solutions for growers of all kinds, helping them achieve their goals and maximize their yields.
