What is DeFuse and what does it do?
DeFuse is a water and nutrient conditioner used to improve root-zone hygiene by suppressing pathogens, algae, and biofilm. It’s not a nutrient or systemic product—it works externally to keep roots and growing systems cleaner so your plants can feed and grow without microbial interference.
What problems does DeFuse help with?
DeFuse is commonly used to manage root rot, powdery mildew, botrytis (bud rot), algae, slime, and clogged drippers. It helps clean up the root zone and system, making it a go-to for growers facing water-borne pathogens or mildew pressure. It also supports healthier roots in “mystery droop” scenarios caused by poor root hygiene.
Can I use DeFuse in hydroponics, coco, soil, or with houseplants?
Yes—DeFuse is suitable for all major growing media including hydroponics (DWC, RDWC, NFT), coco coir, soil, and indoor plant setups. It’s also safe for seedlings and cuttings when used at a lighter dose.
What’s the correct DeFuse dosage for plants?
For young plants, use 0.5 mL per litre. For established plants, 1 mL per litre is common. For heavier issues, up to 5 mL per litre can be used short-term. Always start low and increase only if needed.
Can I use DeFuse for both prevention and treatment?
Yes. Use lower doses weekly to prevent problems, or stronger doses as a short-term treatment when facing algae, rot, or mildew. Many hydro growers add it with every reservoir change for consistent root-zone hygiene.
Can I use DeFuse as a foliar spray?
Yes—DeFuse is commonly used at 0.5 mL per litre as a foliar spray for powdery mildew or bud rot pressure. Spray when lights are off (or early morning outdoors) and avoid soaking flowers, especially in humid conditions.
Does DeFuse leave residue or burn leaves?
At the correct dilution, DeFuse is designed not to leave harmful residues. However, overdosing or spraying under intense light can stress leaves. Always spray in low-light conditions and test a small area first.
Can I use DeFuse with microbes, enzymes, or other additives?
DeFuse is antimicrobial, so it can reduce both harmful and beneficial microbes. If you're running a "living system," go light and avoid mixing with other sterilising agents. It’s generally safe with enzymes and nutrient brands when used properly.
What’s the best way to mix DeFuse into my nutrient solution?
Add nutrients first, mix well, then add DeFuse and mix again. Adjust your pH last. You can add it to an existing reservoir—just circulate thoroughly and recheck pH after.
Will DeFuse affect pH or EC?
DeFuse usually doesn’t impact EC and has minimal effect on pH, but always test your solution after adding it—especially in precision hydro setups.
How quickly does DeFuse start working?
In hydro, you may notice a cleaner smell and clearer reservoir within a few days. Long-term results like healthier roots and fewer mildew outbreaks depend on environmental factors being controlled too.
What are the most common mistakes when using DeFuse?
Overdosing, using it as a band-aid for warm water or light leaks, and trying to run a “living system” while using sterilising products. Pick a consistent approach and avoid mixing too many treatments at once.
How should I store DeFuse?
Store DeFuse in a cool, dark place with the cap sealed tight. Avoid direct sunlight or hot storage areas like sheds. If it looks or smells off, don’t use it.
What should I do if DeFuse arrives damaged?
Take clear photos of the damaged bottle and packaging immediately and contact us so we can sort it quickly. We’ll help with a replacement if needed.
Is DeFuse suitable for commercial and home grows?
Yes—DeFuse is used in both hobby and commercial grows. Pathogen control and clean systems are critical regardless of scale, and DeFuse fits well into any hygiene-focused grow plan.
