Dutch Master provides high quality hydroponic nutrients and additives. It is produced using pharmaceutical grade chemicals to prevent the heavy metal concentrations found in other chemical based nutrients due to impurities in the base chemicals. Dutch Master is developed under the supervision of a well respected doctor of plant physiology and biochemistry. Born in 1998 through the need of a guaranteed, high quality range of hydroponic nutrients and additives. I had a vision and implemented the vision through to a final product. My design brief was simple! Use the best available chemicals, with the best available water and mix it all using the best available equipment and the latest, state of the art technologies! Designed by our inhouse, full time Doctor with a PhD in Plant Physiology and Bio-Chemistry. This man was previously a head lecturer at a world renown University. We have always had the best Plant Sciences people designing the end product for you! Obviously, we continue to make our products better and better through constant testing and trials in conjunction with leading Universities around the world to keep Dutch Master at the cutting edge of technology.
