Mike Thurow
President, CEO & Founder

Vision is my sixth sense. With a broad knowledge of the agricultural & horticulture markets worldwide, Spectrum has been blessed with success in developing new products for our markets. The challenge is getting growers to change and measure things they never measured before. We know that producers and researchers need more data in order to make better, objective decisions. The scarcity of water worldwide and the need to protect the environment will drive our future strategy.  Spectrum is fortunate to have passionate employees who are focused on delivering exceptional customer satisfaction.

Ralph George
Director Of Sales Europe, Middle East, and Africa







My passion is bringing new technologies to farming communities in the EMEA region. As the global population dynamic increases, agriculture strives for new technologies to ensure we can feed the world based on a forecast of 9 Billion people in 2050. Growers are faced with perpetual resource constraints such as water scarcity, plant protection solutions and the lack of additional land to increase production. Having 30 years’ experience in irrigation and integrated crop agronomics, it is apparent growers require more measurement tools and methods to ‘Measure to Know’ plant and soil requirements to optimize crop production.
