My first experience with SumaGroulx was in the spring of 2012. By the time I heard about SumaGroulx I had already planted most of my High Tunnel into salad greens.(Lettuce, Spinach, Radishes) On strictly a trial basis I decided to use the product on these crops. Two weeks later I was amazed at the health of the plants along with the growth and color. I was so pleased with the production of these crops that I used SumaGroulx on Tomatoes, Peppers, Com, and Hay. Due to the higher level of production on all the crops using SumaGroulx last year, the decision was made to apply SumaGroulx to the entire farm in 2013.
