Part II: How to Prevent & Control Grow Room Pests in Hydroponics
Just like using sun cream before stepping outside, pest prevention is always easier (and cheaper) than the cure. Once pests are inside your grow room, your plants, yields, and hard work are at risk. While no method guarantees 100% prevention, with a few simple tools and regular checks, you can significantly lower the chances of infestation and maintain a healthy grow.

1. Use Grow Room Accessories for Early Detection
- Sticky Fly Traps - Inexpensive, effective, and ideal for catching flying insects like fungus gnats early.
- Bug Barriers – Stop pests at the source by covering intake fans and ducting.
-
Pocket Microscope – Accurately identify tiny insects like spider mites to choose the right treatment.
2. Disease & Pest Control Products
There’s no one-size-fits-all solution. Depending on your pest problem, these targeted options can help:
-
Guard ‘N’ Aid for Thrip – Kills all stages of thrips, safe for indoor and outdoor crops.
-
Spray & Grow Spider Mite Protection - Natural spray safe throughout growth.
-
Silver Bullet Mist - Kills 99.99% of bacteria and sterilises grow areas.
Be cautious when using oil-based sprays around beneficial insects.
3. Use Fumers & Vapourisers for Whole-Room Coverage
Sometimes a more aggressive treatment is needed for hard-to-reach pests:
-
Fortefog Fumers – Permethrin-based smoke bombs available in multiple sizes.
-
Sulphume Evaporator – Controls fungal spores and flying pests using sulphur vapour. Note: Stop 2–3 weeks before harvest.
4. Biological Pest Control – Live Predators
For a completely natural pest control strategy, consider beneficial bugs:
-
Hypoaspis for Fungus Gnats – Soil-dwelling mites that target larvae.
-
Phytoseiulus for Spider Mites – Swift, effective red spider mite predators.
-
Amblyseius for Thrips – Prey on thrips and young mites, supplied in breeder sachets.
5. Control Pythium (Root Rot)
High temps mean high risk for root diseases like Pythium. Protect your roots using:
-
Root Rot X – Quickly kills bacteria and removes established biofilm in a single treatment
-
Hailea Water Chiller – Keeps nutrient reservoirs cool and oxygen-rich.
