The Garden King Digital Hygrometer with Probe is a practical temperature and humidity monitor for grow rooms, grow tents, propagation areas, greenhouses and other controlled growing environments, with an external temperature probe for monitoring a second location.
Temperature and relative humidity are two of the most important environmental measurements for indoor growers. This digital thermo-hygrometer provides an easy-to-read display of current conditions while also recording minimum and maximum readings, helping growers understand how their environment changes between checks.
Unlike the standard Garden King Hygrometer, this model includes a wired external temperature probe. This allows the main display to remain in one position while temperature is measured at another, making it particularly useful for comparing different parts of a grow room or monitoring an area that is difficult to view directly.
The combination of temperature, relative humidity and min/max memory makes this a simple but valuable tool for checking the performance of extraction fans, heaters, humidifiers, dehumidifiers and other environmental-control equipment.
Why choose the Garden King Hygrometer with Probe?
- Temperature monitoring - quickly check temperature within the growing environment.
- Relative humidity monitoring - displays humidity alongside temperature for a clearer picture of environmental conditions.
- External temperature probe - monitor temperature at a second position away from the main display.
- Minimum temperature memory - identify how cool the environment became between checks.
- Maximum temperature memory - detect temperature peaks that may otherwise go unnoticed.
- Min/max humidity memory - helps reveal periods of excessive or unusually low relative humidity.
- Large digital display - clear readings for quick environmental checks.
- Useful day and night monitoring - review environmental extremes after lighting and ventilation cycles have changed.
- Ideal for grow rooms and grow tents - straightforward monitoring without a complicated control system.
- Useful throughout the crop cycle - suitable for propagation, vegetative growth and flowering or fruiting environments.
What does the external probe do?
The external probe provides an additional temperature measurement away from the main hygrometer. This makes the probe version particularly useful where temperature needs to be checked at a specific location while the display remains somewhere convenient and easy to read.
For example, the main unit can be positioned where it measures general room conditions while the probe is placed at canopy level, in a propagation area or another location where temperature is particularly important.
It is important to note that the external probe is used for temperature measurement. Relative humidity is measured by the main hygrometer unit.
Monitor temperature & humidity together
Temperature and relative humidity interact continuously within a growing environment. As temperature changes, relative humidity can change even when the actual amount of moisture in the air remains similar.
Monitoring both measurements therefore gives growers a much clearer picture of environmental conditions than temperature monitoring alone.
This information can be used when adjusting extraction, circulation, heating, humidification and dehumidification equipment, helping maintain a more consistent environment around the crop.
Min/max memory reveals what happens when you are away
A current temperature or humidity reading only shows conditions at the exact moment you check the display. The minimum and maximum memory function provides additional information about environmental extremes that occurred since the readings were last reset.
This is especially valuable in grow rooms because environmental conditions can change substantially between the light and dark periods.
Temperatures may climb during peak lighting periods, while humidity can increase as the room cools after lights-out. Reviewing the recorded minimum and maximum readings makes these changes much easier to identify.
Where should I position the hygrometer?
Position the main Garden King Hygrometer where it can measure representative conditions within the growing environment. For crop monitoring, a position around plant canopy height is generally useful.
Avoid placing the main unit directly in front of an intake, immediately beside a humidifier or dehumidifier, directly beneath intense lighting or against a hot or cold surface. These positions can produce readings that do not accurately represent the wider growing environment.
The external probe can then be positioned at a second point where additional temperature information is useful.
Useful applications for the external temperature probe
The addition of a remote probe makes this model more flexible than a basic all-in-one thermo-hygrometer.
- Compare temperature at canopy level with the location of the main display.
- Monitor a propagation area while keeping the display easily accessible.
- Check temperature in a different section of a grow tent or grow room.
- Investigate suspected hot or cold spots.
- Compare conditions close to an intake with the wider room environment.
- Position the display outside a difficult-to-access monitoring point while leaving the probe inside.
Garden King Hygrometer with probe or without probe?
| With Probe | Includes an external temperature probe, allowing temperature to be monitored at a second position away from the main display. |
|---|---|
| Without Probe | Simple all-in-one monitoring of temperature and relative humidity at the location of the main unit. |
For straightforward room monitoring, either version can provide the essential temperature and humidity information growers need. Choose the probe version when the additional remote temperature measurement would be useful.
Ideal for grow rooms & grow tents
Environmental monitoring removes much of the guesswork from indoor growing. Without reliable temperature and humidity measurements, it can be difficult to know whether extraction, heating or humidity-control equipment is actually maintaining the intended conditions.
The Garden King Hygrometer provides immediate information from the digital display, while the min/max memory helps identify environmental changes that occurred when the grow room was unattended.
The external temperature probe adds another useful data point, allowing growers to compare temperatures at different positions and identify potential environmental inconsistencies.
Useful from propagation to flowering
Temperature and humidity remain important throughout the growing cycle, although the preferred conditions and environmental challenges change as plants develop.
Young plants and cuttings can be particularly sensitive to moisture loss, while larger established crops can release considerable quantities of water vapour through transpiration.
Monitoring environmental conditions throughout the crop cycle allows ventilation, heating and humidity-control equipment to be adjusted as plant size and environmental demand change.

Garden King Digital Hygrometer with Probe FAQs
Does this Garden King Hygrometer come with a probe?
Yes. This version includes a wired external temperature probe.
Does the external probe measure humidity?
No. The external probe is for temperature measurement. Relative humidity is measured by the main hygrometer unit.
Does it record minimum and maximum readings?
Yes. Min/max memory helps identify environmental extremes that occur between checks.
Why do I need a hygrometer in a grow room?
A hygrometer allows you to measure relative humidity rather than estimating it, while the temperature readings help assess the overall growing environment.
Where should I put the hygrometer in a grow tent?
For general crop monitoring, position the main unit in a representative location around canopy height and away from direct intake airflow or intense radiant heat.
Where should I put the external temperature probe?
Place the probe where a second temperature measurement would be useful, such as another part of the canopy, a propagation area or a suspected hot or cold spot.
Can I compare two temperatures with this hygrometer?
Yes. The probe version allows temperature at the main unit and temperature at the external probe position to be monitored, making it useful for comparing different areas.
