I maintained a small hydroponic alfalfa sprout farm in Rockville, MD. The mission was to maintain the hydroponic sterile growing machines, adjust ballasts , change ballast. Lube and check all conveyor belts. Taking inventory of all the materials, chemicals, supplies that went into production. Sometimes I would have to deliver the sprouts all night to various stores: whole foods, giant, Keenys, Jc beanssprout, etc...
