Know before you buy
HYSHIELD uses Chitosan, a natural compound derived from crustacean shells, to trigger the plant's own immune response. By 'tricking' the plant into thinking it is under attack, it proactively strengthens its defenses against pests and pathogens.
Yes, it is designed for continuous use from the seedling stage all the way through to harvest. Regular application ensures your plants maintain a heightened state of resilience throughout their life cycle.
Yes, HYSHIELD improves a plant's overall vitality, which helps it better withstand fluctuations in temperature and other environmental stressors.
It is neither in the traditional sense; it is an immune system stimulant. While it helps deter pests and pathogens, its primary function is to boost the plant's natural health and yield rather than acting as a direct chemical treatment.
Because the formula is a liquid concentrate that is not water-soluble, you should follow the specific dilution and application instructions provided on the product label to ensure it is properly distributed for your plants.
