    Putting your Plant's Health First

    Your plants overall health is the most critical part of your grow. If your plants immune system isn’t strong and healthy your crops yields will be significantly reduced.

    HYSHIELD™ tricks plants into thinking they are being attacked by pests and, as a result of this perceived infestation, the plant’s immune system goes into protective mode.

    These natural defense mechanisms not only stimulates the plant immune system but also keeps pathogens and pests at bay.

    Our unique formula when applied to crops as a foliar spray or drench, can increase your plant’s resilience to survive in high heat and cold stress environments.

    Designed to be compatible with water-soluble nutrients & supplement programs, HYSHIELD™ can help boost your yield and enhances conditions for better plant growth.

    Effective in all Growing Media & Growth StagesEnhanced Flowers and Fruit Reduces Transpiration Without Lower Crop Output Improves Plant Survival in High Heat & Cold EnvironmentsSupports Nutrient UptakeManufactured in a facility whose quality management is certified ISO 9001:2015

    HYSHIELD™ Ingredients

    HYSHIELD’s™ unique formula is derived from exoskeletons of crustaceans. Chitosan, the active ingredient in HYSHIELD™, is extracted from crab shells, which are a by-product of the crab fisheries.

    Chitosan as a derivate of the naturally occurring compound Chitin, when given to plants helps activate the plant’s natural defense mechanisms fighting any potential diseases, pests and pathogens.

    HYSHIELD™ has been created with an environmentally sustainable approach in mind using crab and shrimp shells that would otherwise be discarded in landfills.
    Our innovative formula provides the necessary boost your plants require.

    Application Rate:

    FOLIAR APPLICATION: Dilute 0.12 – 0.25 oz per gallon (1 mL – 2 mL per L) of water and spray with lights turned off on foliage 3-5 times per week.

    HYDROPONICS/SOIL/AND OTHER GROWING MEDIUMS: Mix 0.12 – 0.25 oz per gallon (1 mL – 2 mL per L) of water or nutrient solution. Recommended to be used with every watering or as determined by your feeding schedule. (Only use with water soluble nutrients)
