Hygrozyme HYSHIELD Natural Plant Protectant - 4L

Support Plant Defences Through Every Stage - 4L

Plants under stress from pests, heat, cold or dry conditions can lose growth and vigour. Hygrozyme HYSHIELD Natural Plant Protectant uses chitosan, a derivative of chitin, to stimulate the plant's own immune response so it is better prepared for those pressures. Its high molecular weight chitosan acts as a slow-release capsule that supports the plant over the grow cycle.

The 4L bottle suits growers who apply a protectant regularly across several plants or a small to mid-sized indoor room. It gives enough volume to build a routine without committing to a larger container.

Key Features & Benefits

• Chitosan active ingredient — stimulates the plant's natural defence response.
• Slow-release action — high molecular weight chitosan offers long-lasting support through the grow cycle.
• Root zone and foliage coverage — builds a protective layer that strengthens with repeated application.
• Stress resilience — helps plants cope with cold, heat and drought conditions by reducing transpiration.
• Recycled source material — the chitosan is extracted from crustacean shells that would otherwise be discarded.

Who Should Use Hygrozyme HYSHIELD

Home gardeners and licensed commercial growers who want to support plant health during vegetative growth and flowering will find it useful, in soil, coco and hydroponic systems alike.

Frequently Asked Questions

Q: What is HYSHIELD made from?
A: Its active ingredient is chitosan, a derivative of the naturally occurring compound chitin. The chitosan is extracted from recycled crustacean shells.

Q: How does it work?
A: It stimulates the plant's immune system so the plant moves into a protective state. The high molecular weight chitosan releases slowly, supporting the plant over time.

Q: Can I use it in hydroponic systems?
A: It is intended for the root zone and foliage. Check the label for application method and rates for your system before use.

Q: How much do I use?
A: Follow the dilution and frequency directions on the bottle label. Repeated applications are described as strengthening the protective effect.

Q: What is chitosan?
A: Chitosan is a compound derived from chitin, a natural material found in crustacean shells. In plant care it is used to trigger the plant's own defence responses.

Q: Is it a replacement for good cultivation practices?
A: No. It supports plant resilience, but it works best alongside proper nutrition, climate control and hygiene. Check local rules on registration and use for your area.
