  • Do I need to protect my crops?
    Crop protection is the smartest way to cultivate valuable produce. By choosing to invest in a crop protection system, you are choosing to invest in your business and reduce the risks that are out of your control. Most growers who have faced crop loss due to storms prior to harvest go on to cover their crops for future years. Research is also showing that sunburn will become a major factor during the next 10-20 years and that growing class 1 fruit will depend on anti-sun netting.
