Spray-N-Grow treated plants were also healthier, more vibrant, more stress resistant and had a better developed root system. 

All plots in Dr. Nightingale’s tests received the same fertilizer, insecticides, water, etc. Spray-N-Grow application was the only difference. According to Dr. Nightingale “fruit and vegetables produced by Spray-N-Grow treated plants were tastier, sweeter and more succulent.” The bell peppers from the treated plants had thicker walls and a sweeter flavor than the control plants. 

Spray-N-Grow increased the sugar content on all plants tested – apples, grapes, and even tomatoes. Spray-N-Grow also caused most crops to mature early – some by as much as 2 to 3 weeks. Growers in Texas and Florida reported picking Spray-N-Grow treated squash 14 days before the control squash was ready. 

Growers, researchers and agriculture businesses are also using and testing Spray-N-Grow on: hops, potatoes, eggplants, onions, garlic, mint, asparagus, etc.
