Aqua One Digital Thermometer ST-3

Keeping track of your soil temperature is a key aspect of growing health plants from seed or cuttings. A temperature that is too hot can ruin a crop.  The temperature for vegetable plants should be 19°C - 24°C, with the exception of chilli seeds that like 30°C.

These are also ideal for measuring the temperature of fish tanks and your hydroponic water reservoir.
