Introducing ProGuard Air Sanitizer for Grow Rooms

Mold & Mildew Prevention for Hydroponics

If you’ve ever grown indoors, you’ve likely battled molds and mildews that can quickly compromise an entire crop and jeopardize microbial testing. To meet growers’ demand for cleaner, safer environments, GrowersHouse now offers three ProGuard air sanitizers from Innovative Solutions. These indoor air purifiers are available to international buyers and to growers in 49 U.S. states (not available in California). Below, we explain how ProGuard works, why air sanitation is now core to best practices, and which model fits your space.

Why Grow Rooms Need Air Sanitation

Air sanitization prevents the onset and spread of powdery mildew and other molds that thrive in the high-humidity conditions common to hydroponic and controlled-environment agriculture. Because powdery mildew is notoriously difficult to eradicate once established, proactive prevention is essential. A grow room ionizer or air sanitizer reduces airborne and surface-borne pathogen pressure before it can impact photosynthesis, nutrient uptake, and overall plant vigor—helping crops meet stringent microbial testing standards at harvest.

Key Facts About Molds & Mildews (Especially Powdery Mildew)

  • Powdery mildew (white/gray growth) is caused by multiple fungi and spreads rapidly across plants and spaces.

  • Spores hitchhike via ventilation, exhaust, pets, tools, clothing, and personnel—any moving vector can transport them.

  • Dormant spores remain invisible until conditions align; powdery mildew often has a 4–7 day post-inoculation window before symptoms appear.

  • Infection suppresses photosynthesis, reducing energy capture and nutrient use efficiency across seedlings, clones, veg, and flowering plants.

  • Many fungicides that could suppress mildew are restricted or can degrade bud quality and safety.

  • Contaminated crops are unsafe to consume and likely to fail regulatory mold/microbial testing.

The Latest in Grow Room Air Sanitizers

Modern grow room air sanitizers “clean” the environment by removing or neutralizing airborne pathogens and spores. The most effective solutions—such as ProGuard—use UV-driven photocatalytic processes to convert moisture molecules into a low-level ionized vapor that actively kills pathogens. Unlike systems that release harsh chemicals or ozone, this approach focuses on creating an active, distributed sanitizing effect that works in the air and on surfaces.

The ProGuard Difference

ProGuard from Innovative Solutions uses Active Sanitization Distribution to deliver sanitizing agents throughout the environment, targeting pathogens at their source. Through photocatalytic oxidation, UV energy and a proprietary catalyst transform air moisture into a mild hydrogen peroxide vapor that actively kills up to 99.9% of pathogens in high-density, high-humidity commercial grow rooms. The outcome is a cleaner environment that supports plant health and helps crops pass microbial testing.

Models & Coverage (120V/240V)

  • ProGuard Defender DXM 100 with MCI — Proactive air & surface sanitation for high-load spaces (grow rooms and drying rooms). Covers up to 500 sf / 7,000 cf. Wall or ceiling mount. ~25 W power draw.

  • ProGuard Defender DXM 50 with MCI — A compact unit for smaller grow rooms up to 500 sf / 7,000 cf, as well as corridors, trim rooms, or processing rooms. ~25 W power draw.

  • ProGuard DXM Mini — Built for spaces up to 250 sf / 3,500 cf, ideal for small grow rooms, dry rooms, and hallways. ~14 W power draw.

Benefits for Hydroponic Growers

For hydroponic systems, where environmental control is the backbone of productivity, reducing pathogen load directly protects plant surfaces, nutrient film interfaces, and canopy microclimates. By lowering the baseline risk, ProGuard systems help preserve canopy photosynthetic efficiency, stabilize transpiration and VPD strategies, and safeguard quality during critical flowering and drying phases. Most importantly, proactive air sanitation improves the likelihood of passing microbial testing—protecting revenue and reputation.

Protect Your Crop with ProGuard

Considering the cost of a single crop loss, an indoor air sanitizer is a straightforward ROI decision. Many commercial growers recover the investment in a single mildew-free run. If you want to avoid reliance on fungicides and the stress of invisible, dormant spores, it’s time to fine-tune the last part of your environment: the air itself.
