A greenhouse thermometer that records maximum and minimum temperatures is essential when providing adequate ventilation, overwintering in a greenhouse or planning out what frost protection you will need.

Why Use a Hygrometer?

A hygrometer is a device that allows you to monitor humidity levels. High levels of humidity can be detrimental to a plant’s health by encouraging the build-up of fungal plant disease. By monitoring and tracking the humidity with a digital hygrometer, you can ensure appropriate and timely ventilation is in place and ensure healthy growth.

It is important to monitor the temperature of your growing environment to ensure you can adapt to the weather and keep your plants healthy and happy.

Making the most of your Thermometers

To make the most of your home, greenhouse or garden thermometer, monitor and record the variation in temperatures on a daily basis. By using a digital max/min thermometer, you can track the highest and lowest temperatures within a set period of time. By recording this information, you can anticipate likely variations in temperature and plan accordingly.

When positioning your thermometer, make sure you place it in the best place for monitoring the conditions your plant will experience. Raised areas will tend to experience slightly warm temperatures and shaded areas may experience cooler temperatures.  It is always worth considering the use of multiple thermometers to get a better understanding of your growing environment.
