TRIAL SUMMARY
1. Spray-N-Grow increased yield by weight 121.0%
2. Spray-N-Grow increased average head weight 51.7%
3. Spray-N-Grow increased marketable heads 30.0%
4. Spray-N-Grow treated crop had earlier crop establishment and earlier head development
5. Spray-N-Grow treated heads were of better marketable quality after 10 day storage period
Comments by Dr. Morgan
“Foliar fertilization with Spray-N-Grow can result in not only more rapid plant establishment and earlier growth with greater final head weight (yield), but improved shelf life – an important consideration for any hydroponic producer.”
