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.
