    The product is in stock

    We have been designing and building energy and water efficient hydroponic systems, blending plant foods and biostimulants for over 25 years... AND we know how to use them to grow thriving crops.

    American Hydroponics (AmHydro) is an enterprise run by a group of individuals who have financial and lifestyle ambitions that are tied to its success. The company will continue to be known for its innovation by leading the industry with easy-to-access, high-performance horticultural products, greenhouse supplies, resource conservative equipment and knowledge as well as unique products and knowledge that no one else in the industry has.


    Some facts about how hydroponic nutrients are made:

    Liquid nutrients that are found in every hydroponic gardening store are made by dissolving mineral powders in water to make concentrates. A hobby grower pays a premium to buy these colored liquid concentrates, as they are ready-to-use. Some hobby growers think, "the cooler the label, the ‘better’ the nutrient". Not necessarily!  The fact is, ALL nutrients will grow plants or manufacturers wouldn’t spend $ or jump all the registration hurdles to sell them. Many manufacturers focus on feed schedule complexities so growers must buy all the various parts to do well. Is that all really necessary to grow thriving plants? For a hobby grower, it may be… for a farmer, it’s a different story.

    Increasing Your Profit

    If you are a farmer, you’re in business. You sell what you grow for a profit. To increase your profit, you either increase your prices or decrease your expenses. If markets become too saturated, it may not be wise to increase your prices and yet remain competitive. Your only other option is to decrease your expenses.

    One way to do that is to mix your own nutrients for less than 1/3 the cost. A leading liquid nutrient costs around $.38 per gallon of working solution. Mixing your own costs you around $.11 per gallon of working solution.

    Most commercial growers do not buy liquid hydroponic nutrients, they mix their own with their own water. They must achieve the greatest volume of ‘working solution’ for the least cost with out sacrificing plant performance.

    Evolution Solution

    The Evolution Solution commercial hydroponic nutrient line from AmHydro is formulated specifically for commercial growers. Time-tested (since 1984) crop-specific nutrient formulas in 2-part powder form are in use by 100’s of commercial growers world-wide. If you are a commercial grower and are still using premixed liquids, you may want to change gears and save some money. Once you see how easy it is to mix and apply your own nutrients, your costs will drop and crop performance will not miss a beat.

He learned under the tutelage of Grenville Stocker, who is one of New Zealand's top agricultural chemists/horticulturists.  Michael then became one of the key players responsible for bringing NFT to North America and establishing it as one of the foremost techniques-of-choice in the commercial horticulture industry.

    Michael has written numerous articles for trade journals to promote the use of hydroponic technology, as well as documenting his travels abroad, including Practical Hydroponics & Greenhouses, Growing Edge, Urban Garden, among others.  He was featured in a 2007 episode of the television show California Heartland, a program that chronicles interesting and newsworthy stories in the state's agricultural arenas. In 2004, Michael was awarded the prestigious Green Entrepreneur of the Year Award from Governor Arnold Schwarzenegger, recognizing his significant contributions to the industry and their positive effect on our ecology.

    Michael studied plant physiology, biology and botany at Humboldt State University in California, and has continuously attended many symposiums and industry seminars worldwide.

    He is a member of numerous ecological and horticultural organizations, including the Progressive Gardening Trade Association, Hydroponic Society of America, Union of Concerned Scientists, Natural Resource Defense Council, NorthCoast Environmental Center, as well as Cal Trout and Trout Unlimited.  Additionally, Michael serves on the Scientific Advisory Board of Sky Vegetables. Michael was also a founding director of the Hydroponic Merchants Association.

    Donvieve Udell

    Vice President, Greenhouse Manager, Artist Educator

    Donvieve Udell is Vice President and has sat continuously on the Board of Directors as a founding member since the company's inception in 1984.

    Donvieve is responsible for greenhouse operations in our experimental greenhouses. In 1995, she trained alongside her husband Michael Christian in Australia and New Zealand to learn the Nutrient Film Technique. Her need to express her artistic side is unquenchable, as she continues to teach others and travel worldwide. Concurrent with her work at Amhydro, Donvieve also enjoyed nine years as Education Director for the Ink People Center for the Arts in Eureka, California.

She earned a Master's of Fine Arts degree in Theater Arts from Humboldt State University, California, where she continues to serve as an Instructor and Guest Artist. She also instructs art students in several other schools in California and Oregon.

    She writes, "Art is the breath that keeps me inspired and excited about life. Growing up on the eastern beaches, I developed an intense relationship with nature. As I grew and traveled, so did my curiosity about faraway places and different people. I formed a great appreciation for the art of primitive and exotic cultures.

    Art is an expression of many cultures and their connection to nature, from which our world is now being disconnected in many ways. Disassociation from our primordial being, and attempted dominance over nature, are global challenges. Yet beyond the sadness of this thought, there is hope through nature's constant beauty and mystical environments.

    In honoring our environment, my utmost concern is to be committed and conscious of how I impact it by what I create. I have taken the opportunity to work in the Amhydro greenhouses to fulfill my commitment to nature by growing food that is healthy and nourishing."
