Research Findings:
  • Spray-N-Grow increased yield by weight 19%
  • Spray-N-Grow increased numbers of fruit 9%
  • Spray-N-Grow fruit was larger
  • Spray-N-Grow plants had fruit set before control
  • Spray-N-Grow plants were stronger & had a noticeably thicker stem diameter
  • Spray-N-Grow increased brix 8.6%
  • Spray-N-Grow tomatoes did not experience softening tissue, and end of shelf period was determined by “water loss” whereas untreated fruit often developed soft brown areas & overall softening
  • Taste panel (30 members) …76% claimed the Spray-N-Grow tomatoes tasted sweeter than the control
Comments by Dr. Morgan:
"It appears that Spray-N-Grow affects many plant processes, which in turn influence fruit yield and quality. Spray-N-Grow was shown in this trial to be effective in increasing hydroponic tomato fruit yields and quality."
