Hygrozyme Hyshield Natural Plant Protectant

Plants under stress from pests, heat, cold, or drought don't just struggle in the moment — that stress compounds over the grow cycle, cutting into potential yield and potency. HYSHIELD is an all-natural plant protectant that stimulates the plant's own immune system rather than masking stress after the fact. Its active ingredient, chitosan, is derived from chitin extracted from recycled crustacean shells that would otherwise be discarded in landfills, giving the product an environmentally sustainable sourcing story alongside its performance.

HYSHIELD uses a high molecular weight chitosan that acts as a slow-release capsule, delivering long-lasting support throughout the entire grow cycle. Applied to the root zone and foliage, it builds an invisible protective shield that strengthens with every subsequent application, rather than wearing off between doses. Growers use it to support flower development, essential oil production, and thicker stalks capable of holding up a larger canopy, all while staying compatible with existing nutrient and supplement programs.

HYSHIELD meets all registration requirements for sale and use in Canada (CFIA approved) and in multiple U.S. states, and is manufactured in an ISO 9001 certified production facility for consistent quality in every bottle. It's available in 1L, 4L, 10L, and 20L sizes.
