Hygrozyme HYSHIELD Natural Plant Protectant - 20 L

Support Plant Defenses From Root Zone to Foliage - 20 L

Stress from heat, cold, drought and pests can slow plants down mid-cycle. Hygrozyme HYSHIELD is a natural protectant built around chitosan, a compound derived from chitin, which prompts a plant's own defensive responses. The manufacturer describes a high molecular weight chitosan that works as a slow-release layer for the root zone and foliage and builds with repeated application.

This 20 L container suits growers who treat many plants or run frequent applications across vegetative growth and flowering. It gives a regular indoor grower or a commercial operation a larger supply than a trial bottle.

Key Features & Benefits

• Chitosan active ingredient — works with the plant's own immune responses instead of acting as a conventional treatment.
• Slow-release, high molecular weight formulation — offers lasting support across the grow cycle.
• Root zone and foliage coverage — protects both areas and strengthens with repeated use.
• Sourced from recycled crustacean shells — uses material that would otherwise be discarded.
• Large 20 L format — means fewer reorders for bigger cultivation spaces.

Who Should Use Hygrozyme HYSHIELD

Choose it if you run indoor, greenhouse or hydroponic cultivation and want a plant-support supplement for your routine. It fits growers who apply it regularly and need volume.

Frequently Asked Questions

Q: What is HYSHIELD made from?
A: Its active ingredient is chitosan, a derivative of chitin. The manufacturer extracts it from recycled crustacean shells.

Q: What does chitosan do for plants?
A: Chitosan signals the plant to enter a protective mode, much as it would when under attack. This supports its natural defenses and resilience.

Q: Can I use it in hydroponic systems?
A: The manufacturer describes support for the root zone and foliage. Check the label for application methods and rates that suit your system.

Q: Is it legal everywhere?
A: Registration varies by location. Confirm that the product is permitted where you grow before you buy.

Q: How large is the package?
A: The packaged unit measures 16.2 x 16.2 x 18 in and weighs 50 lb when shipped.

Q: Will it raise my yield?
A: Results depend on your crop, environment and routine. HYSHIELD supports plant health, but it does not promise a particular outcome.
