Misting Control System - Professional Evaporative Balance Arm Leaf Sensor & Irrigation Controller

Misting Control System - Professional Evaporative Balance Arm Leaf Sensor & Irrigation Controller

The Misting Control System is a premium, industrial-grade horticultural solution engineered for the high-precision management of greenhouse humidity and propagation environments. This intelligent system operates on the sophisticated balance arm principle of evaporation, utilising a highly responsive mechanical balance arm sensor widely known in the commercial nursery industry as an electronic leaf. Rather than running on a rigid, inaccurate digital timer, this specialised sensor reacts directly to real-time atmospheric moisture loss. As water evaporates from the screen of the balanced arm, the mechanism tips upward, instantly activating the low-voltage water solenoid valve to launch a misting cycle. This demand-based irrigation ensures your plants receive critical hydration exactly when weather shifts dictate it.

Crafted to excel in demanding nursery environments, the system completely removes the guesswork from misting frequencies during erratic seasonal weather. The robust mechanical architecture acts as a living proxy for your crop canopy, responding dynamically to fluctuations in wind speed, ambient temperature, and solar radiation. By automating the misting intervals based on actual environmental evaporation rates, growers can maintain a continuous, pristine microclimate that radically accelerates rooting percentages while preventing the media over-saturation and root rot commonly caused by blind time-clock scheduling.

Best For: High-precision propagation of cuttings, automated humidity control in commercial greenhouses, demand-based seedling irrigation, and maintaining optimal leaf moisture for tropical plant collections without waterlogging the media.

Key Features:

• Evaporative Balance Arm Leaf Sensor: Features a highly sensitive mechanical electronic leaf that naturally mirrors true leaf transpiration and evaporation rates, ensuring misting cycles only trigger when atmospheric humidity drops.
• High-Reliability 24V Solenoid Valve: Equipped with a professional-grade 20mm water solenoid designed for clean, instant shut-off and long-term durability under high-frequency cycling conditions.
• Safe Low-Voltage Operation: Powered via an isolated 24VAC 930mA control transformer, ensuring an exceptionally safe electrical environment in wet, high-humidity greenhouse settings.
• Modular Plug-and-Play Setup: Supplied complete with a polarised dual-socket power board and all necessary pre-wired leads, allowing for immediate installation with no complex electrical work required.
• Industrial Water Efficiency: Significantly minimises water waste and nutrient runoff by delivering targeted moisture pulses only when environmental changes demand it.

Horticultural Application Profiles

• Cutting Propagation: Maintaining the constant, thin leaf film of water required to halt transpiration stress and dehydration in unrooted clones before they push lateral roots.
• Evaporative Greenhouse Cooling: Utilising the automated mist pulses to quickly depress ambient air temperatures and manage vapor pressure deficits (VPD) during peak summer afternoons.
• High-Light Germination Benches: Ensuring delicate seedling trays or coco plugs never suffer from dry surface crusting in high-airflow, intensely lit propagation zones.

Installation & Plumbing Notes:

• Ready to Use: Simply secure the controller to your benching, plug into a standard power outlet, and splice the 20mm solenoid inline with your incoming water supply line.
• Plumbing Hardware: The base system price includes the complete controller and solenoid kit. Water piping and specific misting nozzles are sold separately.
• Compatible Nozzle Metrics (Available Separately): For optimal system performance, pair with mist heads, which offer a wide 1.2m mist spread and a precision flow rate of 61 Litres per hour when run at 30 psi.

Usage Tip & Sensor Calibration: For absolute tracking precision, mount the balance arm sensor directly alongside your actual plant trays at the exact same height and lighting angle. This ensures the mechanical leaf sensor experiences the identical wind, heat, and light conditions as your true crop canopy, triggering misting intervals that are perfectly harmonised with your plants' true evaporation needs. Keep the screen clean of salt or nutrient crusting by wiping it down gently with fresh water once a month.

Oversized Item Delivery Options

Oversized, heavy, and structural goods ship via specialist freight. Freight is calculated at checkout from estimated packaged volumetric or physical weight. Carrier depot audits may adjust the rate — if the increase exceeds 10%, we will contact you before processing.

Available options include:

✔ Delivery to your closest depot for pickup — default method
✔ Direct delivery — requires an operational forklift on site unless Tailgate Delivery has been specifically requested and quoted (contact us — this cannot be selected at checkout)
✔ Tailgate hydraulic lift delivery — must be specifically requested; contact us for a quote (not available as a checkout option; extra fees apply; required if you do not have a forklift)
✔ Forklift loading at our warehouse (no extra charge if you arrange your own freight)
✔ Direct truck delivery (available in Victoria)

Important Notes:

• Shipping costs vary by location and method
• Any carton or consignment over 25–30kg (or over 200cm) must be palletised
• Without a specifically requested and paid Tailgate Delivery quote, palletised freight requires a forklift on site — otherwise the carrier will redirect to the nearest depot
• Bulky and oversized items cannot be delivered to a PO Box — provide a physical street address
• Failed deliveries, locked gates, unattended sites, or incorrect business/forklift declarations may incur carrier redelivery, demurrage, and restocking fees as set out in our Terms & Conditions

Business Delivery:

• Selecting a business/commercial delivery rate warrants that the address has an operational forklift and certified operator during business hours
• If the carrier cannot unload, the consignment may be redirected to a depot and secondary fees may apply
• Additional fees may apply for failed delivery attempts due to lack of appropriate unloading equipment

See our Terms & Conditions (Article 8) for full freight and delivery rules.

Important Note on Availability & Shipping

Our warehouse is a logistics hub, not a retail showroom. Listing a product online does not mean it is stored at our Thomastown warehouse — many lines ship from supplier hubs (split fulfilment may apply).

How lead times work:

• Product page ETA: The Estimated Time of Arrival (ETA) / lead-time badge shown on the product page at checkout is the agreed delivery timeframe for that order under Australian Consumer Law.
• Metro baselines: Advertised ETAs apply to standard metropolitan zones. Regional and remote addresses may take longer and may attract surcharges.
• Peak seasons: Orders in March–May, August–October, EOFY (June), Black Friday/Cyber Monday (November), and Christmas/New Year (December–January) may automatically add a 2–4 week buffer beyond the product page ETA.
• Supplier-dependent / backordered items: If stock is delayed, we will notify you with a revised ETA. You then have 7 days to accept the new timeframe or cancel for a full refund.
• Adloheat: Custom-made products from Adloheat (Pakenham, VIC) may take 4–12 weeks depending on the order.

Full fulfilment, cancellation, and freight rules are in our Terms & Conditions.

Biosecurity & Interstate Shipping Restrictions

Due to strict state biosecurity regulations, we are unable to ship some products to certain states and territories:

• Potting Mixes cannot be shipped to Western Australia (WA), the Northern Territory (NT), or Tasmania (TAS).
• Seeds cannot be shipped to Western Australia (WA).

Orders placed for these items to restricted states will be cancelled and refunded. It is the customer's responsibility to ensure that the items being ordered can lawfully be delivered to their state or territory.
