Anti-hail nets are protective physical barriers made from durable materials like HDPE that cover crops to prevent damage from hailstones. They work by forming a canopy that absorbs and deflects hail, protecting crops from physical injury, sunburn, and bird damage while still allowing essential sunlight, rain, and air to pass through. These nets are an essential investment for modern horticulture, particularly for high-value crops like fruits and in areas prone to unpredictable weather.
