Cultiv8 - Digital Thermometer & Hygrometer – Precision Climate Monitoring

Cultiv8 - Digital Thermometer & Hygrometer – Precision Climate Monitoring

In a controlled grow environment, what you don't measure, you can't manage. The Cultiv8 Digital Thermometer and Hygrometer is an essential diagnostic tool designed to provide real-time visibility into your grow room’s "vitals." By tracking both indoor and outdoor temperatures alongside relative humidity, this device allows you to identify environmental stressors before they impact your yield. Featuring a plant-safe green backlight and a high-accuracy stainless steel probe, it is the professional standard for monitoring the delicate balance of heat and moisture required for high-performance horticulture.

Best For: Monitoring grow tent temperatures, tracking humidity in drying rooms, measuring reservoir or root zone temps, and identifying overnight climate spikes.

Key Features

• Dual-Zone Temperature Tracking: Simultaneously displays the ambient "indoor" temperature of the unit’s location and the "outdoor" temperature via the external probe, perfect for monitoring canopy and floor levels at once.
  • Min/Max Memory Function: Automatically records the highest and lowest temperature and humidity readings. This is critical for catching "stealth" issues like midday heat spikes or late-night humidity surges when the lights are off.
• Grow-Room Friendly Green Backlight: Equipped with a specialised green light-emitting display that allows you to check your readings during the dark cycle without interrupting the plants’ photoperiod or causing accidental hermaphroditism.
• 1.5m Stainless Steel Probe: Features a durable, water-resistant probe on a generous lead. This allows you to measure temperatures in specific micro-climates, such as inside a propagation dome, deep within the plant canopy, or at the intake vent.
• Precision Humidity Sensing: Measures relative humidity (RH%) with +/- 5% accuracy, helping you maintain the ideal Vapour Pressure Deficit (VPD) for optimal transpiration and nutrient uptake.
• Versatile Mounting Options: Built with a sturdy fold-out stand for benchtop use and a rear mounting slot for easy wall or tent-pole attachment.

Specifications

• Indoor Temp Range: -9°C to +50°C
• Outdoor (Probe) Temp Range: -50°C to +70°C
• Humidity Range: 20% to 90% RH
• Accuracy: +/- 5%
• Probe Lead Length: 1.5 Metres
• Power Requirement: 2 x AAA Batteries (Not included)

Installation & Maintenance Tips

• Strategic Placement: For the most accurate "indoor" reading, hang the unit at canopy height, but away from direct blasts from oscillating fans or HID lamps which can create false "hot spot" readings.
• The Probe Advantage: Use the stainless steel probe to monitor your root zone temperature by placing it near the base of your pots, or use it to track the temperature of your nutrient reservoir to ensure dissolved oxygen levels remain high.
• Daily Resets: Get into the habit of checking and then resetting your Min/Max readings every morning. This provides a clear 24-hour window of environmental data, allowing you to adjust your extraction fans or humidifiers accordingly.
• Battery Care: To maintain maximum accuracy and display clarity, replace the AAA batteries every 6 months, particularly in high-humidity environments.

Ideal For (Uses)

• Grow Tents & Rooms: The primary tool for managing day/night temperature differentials (Diff).
• Drying & Curing: Ensuring humidity stays within the 55-62% range to prevent mold or over-drying of your harvest.
• Propagation: Monitoring the high-humidity, stable-temp environment required for successful cloning and seedling development.
