TRIAL SUMMARY

• Spray-N-Grow increased yield by weight 121.0%
• Spray-N-Grow increased average head weight 51.7%
• Spray-N-Grow increased marketable heads 30.0%
• Spray-N-Grow treated crop had earlier crop establishment and earlier head development
• 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 also improved shelf life – an important consideration for any commercial hydroponic producer.”
