digital greenhouse thermometer hygrometer monitor

A greenhouse thermometer is a must-have accessory. You’re going to want to follow up on the temperature rises and falls inside your greenhouse. Especially during summer and winter it’s important to know when to lower the temperature or when to heat your greenhouse. The ideal temperature in your greenhouse is determined by the plants you are growing. Make sure you do some research on the perfect temperature for your crops.

Take a look at this video that explains the optimal greenhouse conditions:

Temperature might be the first factor you need to monitor, but humidity is a close second. It’s important to know the amount of water vapor in the air as some plants will need a more or less humid environment to grow optimally.

Luckily both of these are easy to measure, all you need is a digital greenhouse thermometer and hygrometer!

Digital greenhouse thermometers and hygrometers

When you want basic greenhouse temperature monitoring, we recommend you to buy a wireless min/max digital thermometer. This greenhouse thermometer will tell you the minimum and maximum temperature of a certain timeframe (usually 24 hours). This allows you to keep a close eye on the temperature inside your greenhouse. Depending on your climate, there’s a huge difference between a sunny day and a chilly summer night. That’s why a good insight in the highest and lowest temperature is essential.

While you can go for a traditional, analog model, we suggest you go for the more advanced digital thermometer. It will make your life so much easier. While a traditional thermometer might be cheaper, we feel it’s definitely worth the slightly larger investment to go for a digital model.

Another big benefit of the digital thermometer is that it’s usually combined with a hygrometer, so you won’t have to invest in two separate measuring devices. You will quickly see the current temperature and humidity  into one display. It just takes a daily check to see whether the conditions in your greenhouse are ideally for your veggies and plants to grow. The good news is that these digital greenhouse thermometers are very affordable. You’ll find a basic one for around $20, so there’s really no good reason not to invest in one!
