Each plant species has its own precise limits, but most seeds grow best at the temperatures listed above. If it’s too cold and the sprouts will grow very slowly or not at all. If it’s too warm, sprout growth can stagnate and, in the worst case scenario, excessive temperatures can allow harmful microbes to grow on the sprouts. For food safety, the temperature of the sprouts must be kept low enough.
It makes sense to grow sprouts, because within a few days the nutritional value of the seeds becomes much more favourable to humans. Sprouts are rich in nutrients that are important for humans, so it is advisable to grow and add them to your diet. Growing sprouts can be done in a small space and in the dark, so anyone can grow their own food at home even if they don’t have a greenhouse. In addition, growing sprouts is an inexpensive and energy-efficient way to add fresh and nutrient-rich food to your diet.
Measure the temperature at which sprouts develop with the RuuviTag and you can make sure that the temperature is high enough, especially in winter. In the summer, the sprout growth environment can become too warm and the sprouts can spoil and cause food poisoning. With a RuuviTag, you can continuously measure the temperature at which sprouts are growing and receive alerts on your phone if the conditions are not optimal.
How do you grow sprouts at home?
- Keep the seeds in a jar filled with water for 8 to 12 hours.
- Strain the water out of the jar so that the seeds remain moist in the jar. This is best done by attaching filter paper or a similarly fine enough filter to the mouth of the jar and leaving the jar upside down for a sufficiently long time.
- Allow the sprouts to grow out of direct sunlight at a temperature of 20 °C to 24 °C or 68 °F to 75°F. Rinse the sprouts a few times a day. Make sure that the sprouts dry out sufficiently after rinsing to allow them to take in oxygen from the air.
- The germination time of the sprouts varies depending on the type of seed, but they are usually ready to eat after 3 to 5 days. You can store them in the refrigerator for a few days Remember to rinse the sprouts every day.

RuuviTag is a Bluetooth sensor that monitors environmental conditions and sends the data directly to your mobile device. The Ruuvi Station mobile app allows you to view real-time accurate measurements and historical graphs. The app also provides customisable alerts to notify you of critical conditions, such as a melting freezer, excessively high bedroom temperatures that could disrupt sleep, or elevated humidity levels in your basement.
