Gro Master, Inc.

Marvin Wastell founded Gro Master, Inc. in 1982 to bring his expertise in nutrition, consultation and formulas to livestock and poultry producers. In the late 1980s, Marvin met Jonathan Kleinsasser from Crystal Spring Colony, who convinced him to try selling a newly patented wet/dry hog feeder in the United States.  The rest, as they say, is history.
