3. Spray-N-Grow fruit was larger

4. Spray-N-Grow plants had fruit set 3-4 days before control

5. Spray-N-Grow plants were stronger and had noticeably thicker stem diameter

6. Spray-N-Grow plants produced a significantly higher number of fruit in the desirable size grades of 80-180 grams

7. Spray-N-Grow increased brix 8.1%

8. 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 and overall softening

9. 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 in a positive manner.”

“Foliar fertilisation with Spray-N-Grow can result in not only improved fruit quality, but also an increase in yields within the same crop – an important consideration for any commercial hydroponic producer.”

We guarantee that your Spray-N-Grow treated crops will produce more than your control plot of the same size and type. Conduct your own trial. Treat both plots the same (fertilizer, water, pesticides, etc.) with the only variable being Spray-N-Grow. Follow all mixing and application directions. At harvest you’ll see the difference! If you are not satisfied, we’ll send a prompt refund.

No questions asked.
