Themometers & Hygrometers for Hydroponics

Hydro Experts stocks a wide range of thermometers and hygrometers to monitor temperature, humidity and other growing conditions for indoor plants, mushrooms, and rare plants. Our digital thermometers and hygrometers offer precise readings to ensure your plants and crops have an optimal environment. 

For continuous monitoring, check out our data-logging thermometers and hygrometers. Wireless models like the Sensorpush HT1, HT.W and HTP.xw use Bluetooth to transmit data to your phone or PC. We also offer gateway options like the Sensorpush G1 to aggregate data from multiple sensors. 

For mushroom grow rooms and indoor greenhouses, look at professional monitoring systems like the Pulse One and Pulse Pro Monitors. These systems track humidity, temperature, light levels and more over time to show trends so you can make adjustments before issues arise. 

Outdoor thermometers are available for monitoring conditions outside your grow area. Many models feature both indoor and outdoor thermometers in one unit for easy comparison. 

Whether you need basic thermometers for spot checks or advanced monitoring systems, Hydro Experts has the precise instruments and data loggers to optimize growing conditions for your indoor plants, mushrooms and crops. Give us a call or visit our online store today!

What is a Hygrometer?

A hygrometer is an instrument used to measure humidity. So in basic terms, it's a humidity gauge.  Humidity is the amount of water vapour in the air. Water vapour is the gaseous state of water and is invisible.

There are a variety of different types of temperature & Humidity meters on the market, including both digital and analog models. Analog hygrometers use a hair or thread that expands or contracts based on the air's humidity.

Digital hygrometers use sensors to measure humidity and typically display a numerical readout. The SensorPush Wireless Thermometer/Hygrometer is our personal favourite because it's a digital hygrometer that uses sensors to measure humidity and displays a numerical readout.

What sets the SensorPush apart from other digital hygrometers is its accuracy. The company boasts +/- 2% relative humidity and +/- 0.5 degrees Celsius. We've also found that the SensorPush is very user-friendly. The device comes with a free app that you can use to track the readings from your hygrometer(s).

Why do you need to stay on top of humidity & temperate in hydroponics?

If you're growing plants in a hydroponic system, then you know that temperature and humidity can have a big impact on plant health. That's why it's important to keep an eye on both of these environmental factors using a digital hygrometer/thermometer.

Temperature plays a crucial role in plant growth. Too hot or too cold and your plants will suffer. That's why it's important to have a digital hygrometer/thermometer combo device in your grow room so that you can keep an eye on both the temperature and humidity.

Humidity is also an important factor in plant growth. Too much humidity can lead to problems like mould and mildew, while too little humidity can cause the leaves of your plants to dry out. Again, a digital hygrometer/thermometer combo device will help you keep an eye on the temperature and humidity to ensure your plants are getting the right amount of both.

So if you're looking for a way to better monitor the temperature and humidity in your grow room, then consider investing in a digital hygrometer/thermometer combo device. It's an essential tool for any serious hydroponic gardener.
