Instructors of the Aquaponics Master Class®

Rebecca Nelson and John Pade

Industry Leaders, Company Founders

Rebecca Nelson and John Pade have extensive experience in aquaponics and controlled environment agriculture.  They provide information, share experience, answer questions and personally interact with all Master Class attendees.

For Rebecca Nelson and John Pade, aquaponics and controlled environment agriculture is not a passing fancy, it is not a get-rich quick scheme and it is not new. It is a passion and it is their life’s work.

They are invited speakers at conferences around the world and they are well known for their common-sense approach and practical methods, designs and philosophies.
