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.
| SumaGrow | Water | |
| Start | Mean height: 5.9 inches
SD 0.2 |
Mean height: 6.5 inches
SD 0.5 |
| End | Mean height: 12.6 inches
SD: 4.3 |
Mean height: 9.3
SD: 2.3 |
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.
