The following results are from a study which was conducted by Dave Ringuette, a Professor at University Hawaii Windward Community College. He studied the effects of a SumaGrow (SG) product on Cacao. The only difference in the plant treatment was the SG product.

The SumaGrow treated plants had a mean height of 12.6, while the control plants had a mean height of 9.3 inches, so SumaGrow increased the mean height by 35.5%

Professor Ringuette noted the water only plants had approximately 15% more mealy bug and beetle damage.
