Quick Answer Multi-function root zone conditioner suppressing pathogens and maintaining a clean rhizosphere. Activates plant immune responses rather than just treating existing contamination. Best suited to preventing root rot and biofilm before infection points establish. Ships fast from within Australia. THC Rhizo Shield is a multi-function root zone conditioner and defence solution to suppress pathogens, maintain a clean rhizosphere, and activate plant immune responses. In any grow system, the root zone is constantly exposed to bacteria, fungi, algae, and viral contaminants. Once established, these form biofilm layers and infection points that cause root rot, block nutrient uptake, and stress plants at a fundamental level. Rhizo Shield combines plant-derived bioactive compounds and microbial control agents to prevent pathogen establishment before it becomes a problem, and correct it when it does. Compatible with hydroponics, coco coir, and soil. Also effective as a foliar spray and equipment steriliser between cycles. Key Benefits Suppresses root rot (Pythium), fungal pathogens, algae, and harmful bacteria Prevents biofilm formation and organic contamination in the root zone Improves oxygen diffusion, nutrient exchange, and root surface activity Activates natural plant defence responses for improved disease resistance Multi-use: root zone, foliar application, and equipment sterilisation Non-toxic, plant-derived, and safe across all grow systems How It Works Plant-derived bioactive extracts, including phenolics, organic acids, and secondary metabolites, disrupt microbial cell membranes and inhibit the growth of fungi, bacteria, and algae at the root surface. The microbial control mechanism creates an environment hostile to harmful organisms without relying on living bacteria, breaking down organic contamination and preventing pathogen re-establishment. A cleaner root zone allows better oxygen diffusion and nutrient exchange, directly improving plant performance. Rhizo Shield also triggers induced systemic resistance, strengthening the plant's own defence mechanisms before infection takes hold. How to Use Add to your nutrient solution regularly to maintain a clean rhizosphere. Apply as a foliar spray to treat fungal outbreaks directly. Use between crop cycles for equipment and system sterilisation. Works across DWC, NFT, aeroponics, coco, and soil. Use preventatively, stopping pathogens early is far easier and less costly than correcting an outbreak mid-cycle. THC Rhizo Shield is a root zone defence system, not just a treatment. Use it to protect your crop from the ground up. Frequently Bought Together O16 Stabilised Oxygen, improves dissolved oxygen in the root zone, creating conditions hostile to anaerobic pathogens like Pythium Nefarious Rhizo Tonic, while Rhizo Shield defends the root zone, Rhizo Tonic stimulates new root growth, pairing protection with active development THC Reskue, if root damage has already occurred, pair Rhizo Shield with Reskue to defend and recover simultaneously Frequently Asked Questions How do I add THC Rhizo Shield to my feeding program? Add THC Rhizo Shield to your nutrient solution after mixing your base nutrient. Always add additives to water rather than directly to concentrated nutrient solutions. Stir well after each addition and check EC and pH before use. Start at the lower end of the recommended dose range and increase progressively, additives are potent and more is not always better. Is THC Rhizo Shield compatible with organic and mineral nutrient programs? THC Rhizo Shield is compatible with most hydroponic nutrient programs including both mineral and organic-based systems. If running a fully organic or biological program, check the formulation, some mineral additives can inhibit beneficial microbial populations. When in doubt, contact us at [email protected] for compatibility advice specific to your setup. Can I use THC Rhizo Shield in soil, coco, and hydro? Yes, THC Rhizo Shield is suitable for use across all growing mediums including soil, coco coir, perlite, rockwool, and all recirculating and run-to-waste hydroponic systems. Dose rates may vary slightly between growing systems, always follow the manufacturer's feeding chart for your specific medium. Does THC Rhizo Shield ship fast within Australia? Yes, THC Rhizo Shield ships from within Australia with fast tracked delivery Australia-wide. Most east coast orders arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.
